Description
TECHNICAL FIELD
[0001] The present invention relates to a device for propelling and
turning a warship or a ship that can advance and turn the warship
or the ship by quickly ejecting seawater introduced through a stem
of the warship or the ship, and more particularly, to a device for
propelling and turning a warship or a ship that can enable to be an
environment-friendly warship or ship due to decrease of a CO.sub.2
discharge amount by saving much fuel while improving mobility of
the warship or the ship and that can improve convenience and
stability when docking.
BACKGROUND ART
[0002] In general, a warship or a ship is classified into an oared
vessel, a sailboat (wind force), a steamboat (mechanical power
generated by coal or oil as fuel), and a nuclear ship (mechanical
power generated by nuclear fuel) by power that moves the ship or
the warship, a name of a steamboat is used for a powerboat
propelled by mechanical power regardless of a kind, but a steamboat
of a narrow meaning indicates a ship having a reciprocating engine
or a steam turbine engine that operates with steam power, and a
motor ship having a gasoline engine, a suction-gas engine, a hot
bulb engine, and a diesel engine is distinguished as a
steamboat.
[0003] Further, in addition to such two boats, an electric
propulsion ship exists, and the electric propulsion ship is
classified into two kinds of a diesel electric propulsion ship and
a turbine electric propulsion ship by a distinction of a generator.
A nuclear ship is a steamboat that makes stream using nuclear fuel
and that rotates a steam turbine by the stream. A gas turbine ship
using a gas of a high temperature and a high pressure instead of
stream is not yet spread, except for some high speed special ship.
According to a propeller, an initial steamship was a water wheel
type paddleboat, but nowadays, a screw propeller ship is generally
used.
[0004] A small craft generally uses three blades and a general ship
generally uses four blades, but in a recent large-sized one shaft
line, a propeller of five blades having good efficiency is much
used. Four kinds of one shaft line, two shaft lines, three shaft
lines, and four shaft lines exist according to the number of a
propeller shaft. Conventionally, it was a rule that in a ship, one
shaft is used for one device, but there is a ship in which one
shaft is used for two devices. Further, by determining a rotation
of a propeller in one direction and by changing an angle of a
blade, a pitch of a propeller is changed and thus a variable-pitch
propeller that can simply perform a forward and backward movement
and stop of a ship may be used in a small craft.
[0005] A screw propeller generally has 3-7 blades, and a spiral
surface of a propeller blade pushes water, a ship advances by a
thrust occurring by a reaction thereof, and a device for propelling
and turning a common warship and ship includes a propelling device
such as a Fixed Pitch Propeller (FPP), which is a single propeller,
a Controllable Pitch Propeller (CPP), and a Contra-Rotating
Propeller (CRP) and a tandem propeller, which are a compound
propeller.
[0006] A screw propeller, which is a propulsion device of such a
conventional warship and ship has developed according to a trend of
increase in speed and size of a warship or a ship, but there is a
problem of a vibration and noise by cavitation occurring when
increasing a speed of the warship or the ship, and in this case,
the cavitation is a phenomenon occurring when a propeller having a
high load rotates with a rotation speed exceeding the threshold
rotation number, and generally, the cavitation indicates a
phenomenon that a bubble filled with vapor or air is visualized and
grew by lowering a pressure in a constant temperature.
[0007] In a propeller, which is such an existing general warship
and ship propelling device, when a load is high, cavitation easily
occurs and thus propulsion efficiency is deteriorated and a
vibration and noise occurs in the warship or the ship, and damage
by erosion and flexure of a propeller blade operates as an
obstructive factor in sailing of the warship or the ship, and for
maintenance of the propelling device, even in an urgent situation,
in a state in which the warship or the ship is stopped, maintenance
should be performed and thus there is a problem that maintenance
work efficiency is deteriorated.
[0008] In addition, in a propeller, because about 35.0 knots are
regarded as a limit of a ship speed, when a ship speed is 35.0
knots or more, due to increase of a vibration and noise, the
propeller hardly operates, except for an emergency situation.
[0009] Therefore, when an urgent situation occurs in a high speed
vessel, a fireboat, a rescue ship, a patrol craft, and a patrol
boat, there is a problem that a warship or a ship requiring a high
speed and mobility cannot perform a function thereof due to
generation of cavitation. Further, when an object that may collide
approaches in an advancing direction, there is a problem that it is
difficult for an existing propeller warship and ship to perform
quick turning and sudden stop, and when a large-sized warship or
ship anchors at a port, a revolution radius thereof is much greater
than that of a small warship and ship and thus there is a problem
that the large-sized warship or ship should anchor with help of a
ship (guide ship) having a relatively small revolution radius.

[0010] (Patent Document 1) Patent Publication No. 10-0956719, page
3, Claim 1, FIG. 1. Patent Document 1 relates to a warship or ship
propelling device registered by applying by the present applicant,
and the warship or ship propelling device including a screw
propeller that generates a propelling force by rotating by a
driving force of an engine and a steering means that transfers a
manipulation force for turning includes: a guide pipe installed at
a location lower than a surface of seawater at one side of the
warship or the ship and piped to pass through seawater in an
advancing direction; a first shaft of the screw propeller that
receives and rotates power from an engine and that is horizontally
disposed, a second shaft connected to the first shaft by gear
engagement with a bevel gear to be vertically disposed and to
rotate by interlocking and having a portion disposed within the
guide pipe, and a third shaft connected to the second shaft by gear
engagement with a bevel gear to be horizontally disposed and to
rotate by interlocking and in which a propeller is installed in an
end portion, wherein the steering means is connected to a steering
shaft by gear engagement to receive a rotation manipulation force
and to perform a forward rotation and a reverse rotation by
interlocking and includes a pipe-shaped steering pipe having a
shape that encloses the second shaft and the third shaft and
bearings that support a rotation of the second shaft and the third
shaft located within the steering pipe. A ship propelling device of
such a configuration allows propulsion and steering of a ship by
guiding water colliding with a stem portion to the screw propeller
side disposed at a stern. However, the warship or ship propelling
device applied by the present applicant has a defect that as a
screw propeller within a guide pipe is supported by bearings, a
load applying to the guide pipe increases and thus structural
stability of the guide pipe is greatly deteriorated. That is, a
guide pipe provided to obtain turning and a propulsive force of the
warship or the ship has one end coupled to a steering pipe
rotatably coupled to the bottom of the warship or the ship, and
within such a guide pipe, the screw propeller and the third shaft
are mounted by bearings and thus a load applying to the entire
guide pipe increases. Therefore, a structural defect occurs in
which a connection portion of the guide pipe and the steering pipe
is easily deformed or damaged, and a long time fatigue load is
accumulated in the guide pipe and thus there is a serious problem
that structural stability is greatly deteriorated.

propelling device registered by applying by the present applicant
in order to solve a problem of Patent Document 1, and in registered
Claim 1 thereof, the warship or ship propelling device including a
screw propeller that generates a propulsive force by receiving and
rotating a driving force from an engine includes a guide pipe
rotatably installed in a lower portion of a stern and in which a
front surface and a rear surface are opened to pass through water;
a steering shaft vertically disposed at the front side of the guide
pipe and in which an upper end portion is located within the stern
to receive rotatory power by gear engagement with a rotation shaft
and in which a driving support portion having an inserting hole in
a side portion is formed in a lower end portion and in which an
idle gear is rotatably provided at the lower side; a reinforced
iron rod having one end connected to the steering shaft exposed to
the outside of the stern and the other end connected to an outer
surface of the guide pipe disposed at a gap from the steering
shaft; a power rotation shaft having one end connected to the
engine to receive a rotation driving force and the other end having
a power rotation gear engaged with a bevel gear to one side of the
idle gear; and a driving shaft having one end inserted into the
insertion hole and in which a driving gear engaged with a bevel
gear is provided at the other side of the idle gear at one side
thereof and having the other end formed integrally with the screw
propeller while being extended to the inside of the guide pipe,
wherein the power rotation shaft and the driving shaft are
horizontally disposed to be orthogonal at both sides about the
steering shaft, and in each end portion of the power rotation shaft
and the driving shaft, a power rotation gear and a driving gear
connected by engagement with a bevel gear to an idle gear of the
steering shaft are disposed opposite, the guide pipe has a
reinforced member that connects each of both ends to an upper
portion of the steering shaft and the guide pipe so as to prevent a
rear end portion thereof from being drooped, and in a lower portion
of seawater of the stem opposite to the stern, a discharge pipe is
penetrated in a width direction, and within the discharge pipe, a
stem screw propeller that receives a driving force from the engine
to generate a thrust for turning by selectively performing a
forward rotation and a backward rotation is provided. In a
propelling device of the warship or the ship of such a
configuration, as a rotation of a guide pipe is limited, in order
to move the warship and the ship backward, because the propelling
device should inversely rotate a screw propeller, a separate gear
conversion device should be applied, and thus a structure thereof
becomes complex, there is a defect that there is difficulty in
maintenance and it is difficult to economically produce.
DETAILED DESCRIPTION OF INVENTION
Technical Problem
[0012] The present invention has been made in view of the above
problems, and provides a device for propelling and turning a
warship or a ship that can convert the resistance applying to the
stem side of the warship or the ship to a propulsive force and that
can improve the mobility and avoidance capacity of the warship or
the ship by enabling the warship or the ship to move in a lateral
direction as well as a front-rear direction.
Technical Solution
[0013] In accordance with an aspect of the present invention, a
device for propelling and turning a warship or a ship includes: a
manifold installed in a lengthwise direction in a lower portion of
the warship or the ship and that discharges water introduced into
the stem side to the stern side; a propulsion means having a lower
end portion rotatably connected to an end portion of the stern side
of the manifold and that ejects water in a side direction; and a
steering means rotatably coupled to an end portion of the stern
side of the propulsion means and that rotates the propulsion means
in a random direction through rotatory power applied from the
outside.
[0014] In accordance with another aspect of the present invention,
a device for propelling and turning a warship or a ship includes: a
manifold installed in a lengthwise direction in a lower portion of
the warship or the ship and that discharges water introduced
through a water inlet opened at the stern side to the stem side
through an upper downward inclined surface, wherein the upper
downward inclined surface is formed at a predetermined segment of
an upper end portion of the stern side; a propulsion means
rotatably connected to an upper end portion of the stern side of
the manifold and having a lower downward inclined surface formed to
correspond to a shape of an upper end portion of the stern side of
the downward inclined manifold and having a horizontal segment
formed to eject water in a horizontal direction; and a steering
means fixed to a bottom surface of the propulsion means and that
rotates the propulsion means in a random direction through rotatory
power applied from the outside.
Advantageous effects
[0015] In a device for propelling and turning a warship or a ship
according to the present invention, as a propulsion means of the
warship or the ship is rotatably provided by 360.degree., the
warship or the ship can revolve by 360.degree. in a lateral
direction as well as a front-rear direction and thus the degree of
freedom of steering of the warship or the ship can be greatly
enhanced.
[0016] Further, because a device for propelling and turning a
warship or a ship according to the present invention can solve a
limit of a propulsive force of an existing screw propeller,
economic efficiency according to high speed sailing of the warship
or the ship can be maximized, the warship or the ship can quickly
turn, and even in a sailing or anchoring state, the warship or the
ship can turn and smoothly anchor without help of a guide ship.
[0017] Particularly, because an auxiliary propulsion pipe installed
at a side surface of the warship or the ship allows a side movement
of the warship or the ship, a revolution moving performance of the
warship or the ship can be further enhanced and a revolution radius
thereof can be reduced to the minimum and thus when the auxiliary
propulsion pipe is applied to an entire warship such as an aircraft
carrier and a submarine as well as a warship or a cruiser, a quick
avoidance movement and an attack to the enemy can be performed.
[0018] These and other objects of the present application will
become more readily apparent from the detailed description given
hereinafter. It should be analyzed that generally using terms
defined in a dictionary have a meaning corresponding to that of a
context of related technology and are not analyzed as an ideal or
excessively formal meaning unless explicitly defined.

[0034] A configuration of a device for propelling and turning a
warship or a ship according to an exemplary embodiment of the
present invention will be described with reference to the
accompanying drawings.
[0035] A device 1 for propelling and turning a warship or a ship
according to an exemplary embodiment of the present invention
includes a screw propeller 6 that generates a propulsive force by
receiving and rotating a driving force from an engine 3. That is,
in order to transfer a rotation driving force, the engine 3 has a
driving shaft 4, and the screw propeller 6 is disposed orthogonal
to one end of the driving shaft 4 to rotate by a structure having a
rotation shaft 7 connected by gear engagement. Further, the
rotation shaft 7 is supported to the inside of the main pipe 11 by
a support frame having bearings (not shown). When it is
characterized in that the screw propeller 6 of such a configuration
is installed at the inside of the main pipe 11, which is one of
elements constituting the manifold 10 to be described later, the
screw propeller 6 of the present exemplary embodiment may be
executed by well-known technology.
[0036] When the warship or the ship advance, the screw propeller 6
performs a function of quickly introducing, guiding, and
transferring water colliding with the stem side into the manifold
10 and determines a propulsion speed according to a speed
thereof.
[0037] Such a configuration is substantially the same as that of a
warship and ship propelling device previously applied by an
applicant of the present invention. However, the present invention
has a characteristic that improves mobility of the warship or the
ship and that enables a stable and quick movement when docking. A
major technical characteristic of the present invention for this
purpose is the manifold 10, the propulsion means 20, and the
steering means 30.
[0038] The manifold 10 includes the main pipe 11 that introduces
water from a water inlet a located at the stem side of a ship to
guide and supply the water to the propulsion means 20 connected to
the stern side; and a plurality of auxiliary pipes 13 each having
one end connected to the main pipe 11 to receive introduced water
and that eject water through selective pipe channel opening and
that are disposed in a width direction of the warship or the ship,
and the auxiliary pipe 13 is provided in plural to move in a left
direction or a right direction of the warship or the ship, as shown
in the drawing.
[0039] Further, the auxiliary pipe 13 blocks a pipe channel by a
valve v when the warship or the ship advances and ejects water
introduced through the main pipe 11, as a valve v of a
corresponding auxiliary pipe opens a pipe channel when the warship
or the ship revolves or when the warship or the ship moves to the
side. Although not shown in the present invention, when ejecting
water through the auxiliary pipe 13, in order to enhance an
ejecting pressure, the auxiliary pipe 13 can selectively switch
water by forming a valve at the stern side of the main pipe 11.
[0040] The manifold 10 of such a configuration may be provided in
various forms, and in the present exemplary embodiment, the main
pipe 11 is installed in a lengthwise direction at the center of a
lower portion of the warship or the ship, a water inlet a is formed
to open the front side located at the stem side, and the auxiliary
pipe 13 is disposed at the left and the right of the main pipe 11
to move the warship or the ship in a width direction.
[0041] Further, as shown in FIGS. 8 and 9, the main pipe 11
constituting the manifold 10 is provided so that a thickness has a
size relatively smaller than a width while having a wide width in a
lower portion of the warship or the ship, and at the left and right
side of the main pipe 11, a plurality of auxiliary pipes 13 may be
formed.
[0042] Further, as shown in FIG. 10A, at the center of a lower
portion of the inside of the warship or the ship, at both sides in
a lengthwise direction, the main pipe 11 having a pair of branch
pipe channels 11a and 11b is provided, and a plurality of auxiliary
pipes 13 having one end connected to each of the branch pipe
channels 11a and 11b of the main pipe 11 to be disposed in a width
direction of the warship or the ship may be formed.
[0043] Further, as shown in FIG. 10B, in a lower portion of a
seawater surface of both side surfaces of an outer surface of a
belly of the warship or the ship, the main pipe 11 having a pair of
branch pipe channels 11a and 11b is provided at both sides in a
lengthwise direction of the warship or the ship, and as shown in
FIG. 11, at the center of a lower portion of the warship or the
ship, a supply pipe 12 is installed in a lengthwise direction, and
a plurality of auxiliary pipes 13 disposed in a width direction of
the warship or the ship are formed at the left and the right of the
supply pipe 12 in which the front side is opened and in which the
rear side is closed.
[0044] Alternatively, the auxiliary pipe 13 may be directly
installed in the branch pipe channels 11a and 11b.
[0045] In a presently operating and using existing warship and
ship, the main pipe 11 and the auxiliary pipe 13 may be installed
and used, as described in FIGS. 10B and 11.
[0046] Further, as shown in FIG. 11, the manifold 10 may include
the main pipe 11 installed in a lengthwise direction at the center
of a lower portion of the warship or the ship, the supply pipe 12
installed in an upper portion or a lower portion along the main
pipe 11 and in which the front side is open and in which the rear
side is closed; and a plurality of auxiliary pipes 13 disposed at
the supply pipe 12 in a width direction of the warship or the
ship.
[0047] In short, it is characterized in that the manifold 10 of the
present exemplary embodiment guides and introduces water colliding
with the stem side when the warship or the ship advances to the
main pipe 11 and generates a propulsive force by ejecting the
introduced water to the outside through the propulsion means 20 in
a high pressure through the main pipe 11 using the screw propeller
6 or generates a propulsive force that revolves the warship or the
ship or that moves the warship or the ship to the side by ejecting
the introduced water through a corresponding auxiliary pipe 13.
[0048] A lower end portion of the propulsion means 20 is rotatably
connected by 360.degree. to an end portion of the main pipe 11
located at the stern 2 side of the warship or the ship to receive
water and to eject the received water in a side direction.
[0049] Such a propulsion means 20 includes a housing 22 rotatably
connected to the main pipe 11, an ejection pipe 21 integrally
formed in a side portion of the housing 22 and having a water
outlet b that ejects the received water, and a rotation support
plate 25 that rotatably supports the bottom of the housing 22.
[0050] The housing 22 is formed in a cylindrical shape, and as
shown in the drawing, a portion of an upper end portion thereof is
inserted into one side end of the main pipe 11 and thus a lower end
portion thereof is rotatably supported. In this case, it is
preferable that the housing 22 is provided to rotate while being
prevented from being separated from the main pipe 11, and in the
present invention, as shown in the drawing, in an upper end portion
of the housing 22, a flange 24 having an extended diameter is
formed, and the main pipe 11 is prevented from being separated by
forming a through-hole (not shown) of a diameter smaller than that
of the flange 24, and the flange 24 and the housing 22 are coupled
by screw fastening and are bonded by welding. A reference numeral g
indicates a ring-shaped bearing member for smoothly rotating the
flange 24 relative to the main pipe 11.
[0051] The ejection pipe 21 is connected to one side of the housing
22 to receive water and to eject the water through a water outlet b
of one side and has a pipe shape disposed parallel to the main pipe
11. The ejection pipe 21 is formed integrally with the housing 22
to have integrally a rotation displacement by interlocking when the
housing 22 rotates.
[0052] The rotation support plate 25 is a support member that
rotatably supports the housing 22 and supports the bottom of the
housing 22. Such a rotation support plate 25 is a plate-shaped
member having one end coupled and fixed to the stern 2 and the
other end having a flat surface to support the bottom of the
housing 22, as shown in the drawing. Further, when the housing 22
rotates, the rotation support plate 25 of the present exemplary
embodiment prevents the housing 22 from moving in a horizontal
direction by protruding upward a circumferential edge portion.
[0053] In the propulsion means 20 of such a configuration, the
housing 22 receives water, having passed through the main pipe 11
of the manifold 10, and water, having passed through the housing 22
is ejected to the outside by passing through the ejection pipe 21
connected to one side thereof, and a propulsive force of the
warship or the ship is generated by such an ejection operation.
[0054] The steering means 30 includes a propulsion gear 23 formed
at an outer surface of the propulsion means 20 and a steering shaft
31 connected by gear engaging with the propulsion gear 23 to
transfer rotatory power.
[0055] The propulsion gear 23 is a gear formed at an outer surface
of the housing 22 of elements constituting the propulsion means 20
and engages with the steering gear 33.
[0056] The steering shaft 31 is a shaft element that receives a
steering force, and in the present exemplary embodiment, the
steering shaft 31 is disposed vertically to the warship or the
ship, and in a lower end portion, which is an end portion based on
the drawing, a steering gear 33 engaged with the propulsion gear 23
to transfer rotatory power is integrally formed with the propulsion
gear 23.
[0057] In the steering means 30 of such a configuration, in order
to adjust a direction of the warship or the ship, when the steering
shaft 31 rotates clockwise or counterclockwise, the steering gear
33 formed integrally with the steering shaft 31 rotates the engaged
propulsion gear 23 by interlocking, and the housing 22 and the
ejection pipe 21 formed integrally with the propulsion gear 23
adjust a propelling direction by turning.
[0058] The steering means 30 may be formed, as shown in FIG. 12.
When describing with reference to the drawing, the steering means
30 according to the present exemplary embodiment includes a
steering shaft 31' disposed in a lengthwise direction of the ship
or the warship, a worm gear 33' formed integrally with an end
portion of the steering shaft 31', and a propulsion gear 23 engaged
with the worm gear 33' and provided at an outer surface of the
housing 22 constituting the propulsion means 20. The steering means
30 of such a configuration is substantially the same as that of the
foregoing exemplary embodiment, except for a difference in which
the steering shaft 31' is horizontally disposed in a lengthwise
direction of the ship or the warship, unlike the foregoing
exemplary embodiment.
[0059] Operation of a device for propelling and turning the warship
or the ship according to an exemplary embodiment of the present
invention having the above-described configuration will be
described and a turning operation of the propulsion means 20 will
be described.
[0060] When a steering shaft 31 that receives a steering force
rotates clockwise or counterclockwise, the propulsion gear 23
engaged with the steering gear 33 of the steering shaft 31 rotates
clockwise or counterclockwise by interlocking. Therefore, as the
propulsion means 20 having the propulsion gear 23 at an outer
surface rotates clockwise or counterclockwise, the warship or the
ship is turned while being propelled by a discharge pressure of
water ejected by passing through the ejection pipe 21 of the
propulsion means 20.
[0061] For reference, FIG. 4 illustrates a state in which the
ejection pipe 21 of the propulsion means 20 that receives a
rotation manipulation force from the steering shaft 31 is disposed
in a right direction based on the drawing, and in such a state,
when water is ejected in a high pressure through the ejection pipe
21, the warship or the ship entirely rotates clockwise.
[0062] FIG. 5 illustrates a state in which the ejection pipe 21 of
the propulsion means 20 that receives a rotation manipulation force
from the steering shaft 31 is disposed toward the stem side based
on the warship or the ship, and in such a state, as water of a high
pressure ejected through the ejection pipe 21 is ejected toward a
stem of the warship or the ship, the warship or the ship moves to
the rear.
[0063] FIG. 6 illustrates a state in which the ejection pipe 21
constituting the propulsion means 20 is disposed in a left
direction based on the drawing, and in such a state, when water is
ejected in a high pressure through the ejection pipe 21, the
warship or the ship entirely rotates counterclockwise.
[0064] In FIG. 7, in a plurality of auxiliary pipes connected to
the main pipe 11 constituting the propulsion means 20, auxiliary
pipes located at the right side based on the drawing are opened,
and in a state in which auxiliary pipes located at the left side
are closed, when water is ejected in a high pressure through the
opened auxiliary pipes of the right side, the warship or the ship
entirely moves to the left side based on the drawing. In this case,
in order to enhance an effective ejection pressure of the auxiliary
pipes, it is preferable to install and switch a valve to prevent
water from being ejected through the propulsion means 20 connected
to the main pipe.
[0065] In another exemplary embodiment of the present invention, in
addition to a turning device of the warship or the ship, for a
small margin movement and turning of the warship or the ship, a
direction adjusting means may be added, and FIGS. 14 to 17
illustrate a direction adjusting means 40 of a turning device of a
warship or a ship according to an exemplary embodiment of the
present invention and a detailed configuration and operation
thereof will be described.
[0066] The direction adjusting means 40 may be added on the
manifold or at one side of a lower portion of the manifold 10 and
includes a plurality of adjusters 41, 43, and 45 formed with a
screw propeller 6 and a rotation shaft 7.
[0067] In operation of three adjusters 41, 43, and 45 within the
direction adjusting means 40 described with reference to FIGS. 14
to 17, as shown in FIG. 14, at one side of a lower portion of the
manifold 10, the adjusters 41, 43, and 45 having the screw
propeller 6 and the rotation shaft 7 are formed in a uniform gap.
In this case, as a screw propeller 6 of each of adjusters 41, 43,
and 45 of the direction adjusting means 40 of the warship or the
ship strongly eject right side water (seawater) to the left side,
the warship or the ship may entirely move by a small margin to the
right side or may turn.
[0068] As shown in FIG. 15, as the screw propeller 6 of each of the
adjusters 41, 43, and 45 of the direction adjusting means 40 of the
warship or the ship strongly eject left side water (seawater) to
the right side, the warship or the ship may entirely move by a
small margin to the left side or may turn.
[0069] FIGS. 16 to 17 illustrate a configuration for turning a
warship or a ship, and in FIG. 16, in the direction adjusting means
40 of the warship or the ship, the screw propeller 6 of the first
adjuster 41 of the stem ejects right side water (seawater) to the
left side, and the screw propeller 6 of the third adjuster 45 of
the stern strongly ejects left side water (seawater) to the right
side to turn clockwise the warship or the ship, and in this case,
in a stop state, the warship or the ship rotates clockwise, and
when sailing, the warship or the ship turns while drawing a circle
clockwise. For turning, the screw propeller 6 of the second
adjuster 43 does not drive.
[0070] Another exemplary embodiment illustrates operation of an
adjuster using when turning a warship or a ship counterclockwise,
and in FIG. 17, in a direction adjusting means 40 of the warship or
the ship, a screw propeller 6 of a first adjuster 41 of a stem
rotates left side water (seawater) to the right side, and the screw
propeller 6 of a third adjuster 45 of the stern strongly ejects
right side water (seawater) to the left side to turn
counterclockwise the warship or the ship, and in this case, in a
stop state, the screw propeller 6 rotates counterclockwise, and
when sailing, the warship or the ship turns while drawing a circle
counterclockwise. For the turning, the screw propeller 6 of the
second adjuster 43 does not drive.
[0071] FIGS. 18 and 19 are views illustrating a device for
propelling and a device for turning, respectively, a warship or a
ship according to a second exemplary embodiment of the present
invention.
[0072] Referring to FIGS. 18 and 19, a device for propelling and
turning a warship or a ship according to a second exemplary
embodiment of the present invention includes a manifold 110
installed in a lengthwise direction in a lower portion of the
warship or the ship and that discharges water introduced through a
water inlet opened to the stem side to the stern side through a
upper downward inclined surface, as the upper downward inclined
surface is formed at a predetermined segment of an upper end
portion of the stern side; a propulsion means 120 rotatably
connected by 360.degree. to a lower end portion of the stern side
of the manifold 110 and in which a lower downward inclined surface
is formed to correspond to a shape of an upper end portion of the
stern side of the downward inclined manifold 110 and in which a
horizontal segment is formed to eject water in a horizontal
direction; and a steering means 130 fixed to a bottom surface of
the propulsion means 120 and that can rotate the propulsion means
120 in a random direction through rotatory power applied from the
outside.
[0073] Here, it is preferable that at the stern side of the
manifold 110, a screw propeller 161 that generates a propulsive
force by receiving and rotating a driving force from an engine is
installed.
[0074] Further, it is preferable that the stern side of the
manifold 110 and a bottom surface of the propulsion means 120 have
a downward inclined surface to avoid, if possible, a friction of
water introduced through an opening of the manifold 110. That is,
as shown in FIG. 18, the bottom surface of the propulsion means 120
and the stern side of the manifold 110 that entirely ejects water
are formed in a streamline shape.
[0075] FIGS. 20 and 21 are views illustrating a device for
propelling and a device for turning, respectively, a warship or a
ship according to a third exemplary embodiment of the present
invention.
[0076] Referring to FIGS. 20 and 21, a propelling device of a
warship or a ship according to an exemplary embodiment of the
present invention includes an acceleration guide pipe 110a
installed in a lengthwise direction in a lower portion of the
warship or the ship and rotatably installed by 180.degree. in a
horizontal direction in an external direction of the warship or the
ship in a lower end portion of the manifold 110 that discharges
water or gas introduced into the stem side to the stern side and in
which at least four direction adjusting means are installed at a
constant gap therein; and a steering means 130 in which a lower end
portion is rotatably connected in an end portion of the stern side
of the manifold 110 and in which the propulsion means 120 formed to
eject water in a side direction to be rotatably coupled by
360.degree. to an end portion of the stern side and that can rotate
the propulsion means 120 in a random direction through rotatory
power applied from the outside.
[0077] Referring to FIG. 22, a propelling device of a warship or a
ship according to an exemplary embodiment of the present invention
includes steering means 130; 131 and 133 installed in a lengthwise
direction in a lower portion of the warship or the ship and having
a lower portion rotatably connected to an end portion of the stern
side of the manifold 110 that discharges water introduced to the
stem side to the stern side and in which the propulsion means 120
formed to eject water in a side direction is rotatably coupled to
an end portion of the stern side and that can rotate the propulsion
means 120 in a random direction by 360.degree. through rotatory
power applied from the outside; and a plurality of direction
adjusting means 113R and 113L horizontally installed at a constant
gap in an external direction of the warship or the ship at both
side surfaces of the warship or the ship so as to turn the warship
or the ship by 360.degree. or to move the warship or the ship by a
small margin to the right side or the left side.
[0078] Here, it is preferable that each direction adjusting means
113 selectively executes operation of rotating seawater to the left
side or the right side, pushing seawater to the front side or the
rear side, or stopping the warship or the ship by blocking water
from advancing with a valve v for an advancing state, an advancing
direction, turn, start, and stop of the warship or the ship
according to a location and a direction of an ejection port.
[0079] Each direction adjusting means 113 includes a plurality of
adjusters formed with a screw propeller, a rotation shaft, and a
switch valve.
[0080] FIG. 22A illustrates a state in which the warship or the
ship sails straight to the front side, and in this case, a screw
propeller of the direction adjusting means 113 generates a
propulsive force toward the rear. FIG. 22B illustrates a state in
which the warship or the ship is stopped, and in this case, because
the valve v blocks water from advancing, the screw propeller of the
direction adjusting means 113 does not operate. FIG. 22C
illustrates a state in which the warship or the ship sails straight
to the rear side, and in this case, a screw propeller of the
direction adjusting means 113 generates a propulsive force toward
the front side. FIG. 22D illustrates a state in which the warship
or the ship are stopped, and in this case, because the valve v
blocks water from advancing, the screw propeller of the direction
adjusting means 113 does not operate. FIG. 22E illustrates a state
in which the warship or the ship rotates to the right side, and in
this case, two direction adjusting means of a lower end portion of
the right side and two direction adjusting means of an upper end
portion of the left side generate a propulsive force, and two
direction adjusting means of an upper end portion of the right side
and two direction adjusting means of a lower end portion of the
left side do not operate by blocking of the valve v. Further, FIG.
22F illustrates a state in which the warship or the ship rotates to
the left side, and in this case, two direction adjusting means of a
lower end portion of the right side and two direction adjusting
means of an upper end portion of the left side do not generate a
propulsive force by blocking of the valve v and two direction
adjusting means of an upper end portion of the right side and two
direction adjusting means of a lower end portion of the left side
generate a propulsive force. Further, FIG. 22G illustrates a state
in which the warship or the ship moves to the right side and in
this case, the direction adjusting means of the right side does not
generate a propulsive force by blocking of the valve v and the
direction manipulating means of the left side generates a
propulsive force. FIG. 22H illustrates a state in which the warship
or the ship moves to the left side and in this case, the entire
direction adjusting means of the right side generates a propulsive
force by opening of a valve v and the entire direction manipulating
means of the left side does not generate a propulsive force by
blocking of a valve v. In this case, the direction manipulating
means that does not operate is returned into a belly of the ship,
and a door of a ship wall is controlled to be closed.
