Paddle aqua-glider used to propel floats, reach remote places and
objects, survey rescue in water
Abstract
Oar, ancient propulsive mean is known many hundreds years ago
and is not exchanged until now. Here is offered a new paddle
device--a paddle aqua-glider able to exchange oars partially and it
is able to expand applicability of manual paddle means much far.
The paddle aqua-glider combines ability to glide forward with
ability to rise up and to function as a paddle when backward force
(such a cord tension) applied to it. If here is no need to propel
floating mean then the paddle glider can function in fleeing mode
of operation that requires slackening and elongating the cord tied
to the glider for it keel rear edge. This allows the glider to
glide away forward freely in each cycle and to reach any desired
distanced place or object on its way delivering help or something
needed. It can also provide remote survey, rescue, hunting,
seizing, etc.

Claims
What I claim as my invention is:
1. Method using a aqua-glider as a paddle based on application of
cord connected to rear edge of the aqua-glider keel; the cord
tension orients the aqua-glider by its wing cross the cord line in
each tension cycle and it experiences impulsive forward
reaction--water resistance of aqua-glider wing treated as
propelling thrust; the aqua-glider also rises up when the cord is
taut and it glides away from gotten height to new position when the
cord is slackened.
2. Method enforcing aqua-glider to get initial height reviving
glide process and based on cyclic application of impulsive force to
the aqua-glider keel rear edge backward that overturns the
aqua-glider by its wing cross the force direction and lifts the
aqua-glider up to the initial height.
3. Aqua-glider alternatively gliding away and rising up to initial
height due to impulsive force cyclically applied backward to the
aqua-glider keel rear edge mainly with taut cord connected to it
and overturning the aqua-glider by its wing cross glide direction
as a paddle; as a result the aqua-glider is able to work in three
modes of operation: paddle mode providing cyclical impulsive thrust
for a floating mean, which a user applies the aqua-glider from
keeping constant the cord length; fleeing mode when the aqua-glider
glides away to a distanced place or object for help, surveying,
hunting or seizing; in this case the user elongates the work part
of the cord; hovering mode displaying the aqua-glider cyclic motion
about the same place without advance; each cycle the aqua-glider
returns to initial position by water surface starting glide
repetition.

STATEMENT REGARDING FEDERALLY SPONSORED R & D
[0002] The author created the invention by himself with own means
in duty free time.

BACKGROUND OF THE INVENTION
[0004] About Oars.
[0005] Until now the only oars are well known as the ancient paddle
mean driven manually.
[0006] It seems, as the oars will never vanish out off human
activity. However, the oars using requires a float to be of special
form like a boat, an oblong raft and soon usually equipped with
rowlocks. We can not use it when swimming or diving. We can not use
it when we are on ice floe. We do not know diverse usage of the
oars.
[0007] Endeavor:
[0008] Here we offer new type of paddle mean sharply changing its
capabilities and methods to use it. Also it opens new opportunities
of usage the same device in variety practical cases. The paddle
device is designed as a paddle aqua-glider linked with a user
through a cord, a cable, a string or a fishing-line.
[0009] As a glider it is able to outset itself far enough from an
user, but as a paddle it is able to stay steady similar to an
anchor when the user or a rower pulls the a cord back. Owing to
design the paddle glider raises up when the user pulls it with the
cord.
[0010] If the user does not paddle (for example stays on the shore)
he slacks away a part of the cord to give freedom to the paddle
glider, which glides far utilizing potential energy obtained at its
rising time. After multiple repetition of described process the
paddle glider gets any place on its way delivering itself as help
or something needed.
BRIEF SUMMARY OF INVENTION
[0011] The general idea of the claimed invention is usage
repeatable recombination of forces applied to the aqua-glider in
order to set it in paddle mode of operation rising it to take
potential gravity energy providing for next cycle moving forward.
The recombination of forces is accomplished by pulling and slacking
the cord attached to the paddle glider keel.
[0012] If the cord is of constant length than the user is a rower
paddling with the paddle glider relocating forward with each cycle.
If the cord increases in its length then the user is rather an
operator remotely enforcing to move forward to new location or to a
remote object to contact or interact with it.
[0013] The paddle glider can be of different size and so be used
for different purposes individually or collectively (by a group of
people).

DETAILED DESCRIPTION OF INVENTION
[0031] 1. Conception. Claim 3)
[0032] The paddle aqua-glider combines two its abilities: first, to
glide translationaly under gravity force; second, to be orient
cross its gliding, to rise up and to function as a paddle under
tension applied to it through taut cord. This type of operation is
named as paddling mode of operation. The cord length is not changed
here. If there is no necessity to paddle then paddle functioning is
not used. And we have two other modes of operation.
[0033] If after rising up the paddle glider returns to initial
position by water surface by pulling it back with the tension the
mode of operation is named as hovering mode of operation. A man
(operator) slackens but does not elongate the cord and the paddle
glider slides forward again to the same remote position. Process is
repeated and the paddle glider accomplishes closed cycle of motions
around the same place. It can be used for fishing if the paddle
glider is rigged with fishing hook and it is small enough.
[0034] If after rising up and cord slackening the paddle glider
instantly slides forward to new remote position then the mode of
operation is named as fleeing mode of operation. The man elongates
the cord by loosing it from a bobbin or a coil.
[0035] 2. Design and Description of Work for the Paddle Glider.
[0036] The paddle glider is very simple device (FIG. 1). It
consists of a foil or a wing 2 connected to a keel 4 with
attachment 3. It is not obligatory but some time it is desirable to
disconnect the wing 2 and the keel 4 in order to pack the paddle
glider when it is stored or transported. As we see (FIG. 1, FIG. 2,
FIG. 5), the keel can be removed from the nest 6 by sliding it out
predetermine unlocking it with the latch 7 fixed to the wing 2 with
the flat spring 11 (FIG. 5). Sliding directions are shown with the
arrow M. The keel holds a streamline sinker 5.
[0037] If we suppose that the glider weight is concentrated in the
sinker 5 then the glider has two basic forces: gravity G and lift L
that are balancing each other. For gliding it is needed that the
hydrodynamic pressure P force (perpendicular to the wing plane) and
the gravity force G should not be coincide and the gravity force
needs to be shifted forward as shown by FIG. 2. In this case the
glider takes forward inclination .beta. (FIG. 4) when it is
released and starts gliding.
[0038] The hydrodynamic force P is resolved into components L
(lift) and T (thrust). The lift L equilibrates the gravity force G
while the thrust T overcomes a hydrodynamic resistance force and
moves the device with velocity V2 (if the cord 8 is not taut).
[0039] A man pulling the cord 8 with the force D overturns the
paddle glider orienting it cross to the cord line 8 (FIG. 6). This
creates hydrodynamic head P. The horizontal component of it is the
desired thrust propelling the floating mean. (claim 1) This
component equilibrates horizontal component of the force D. Also
sum of vertical components of the forces P and D is the lift L
equilibrating the gravity force G. Here we see the simplest case
when the forces L and G are coincide on the line.
[0040] In paddling mode operation the tension D (FIG. 7) enforces
the glider also to rise up with velocity V1. (claim 2) Zeroing the
force D allows the glider first to speed up then to glide with some
velocity V2. The new repetition of the force D revives the
described process of the paddling mode of operation. It is clear
that the velocity V2 is greater than the velocity V of some float
propelled with the paddle aqua-glider.
[0041] 3. Theoretic Basics and Numeric Example.
[0042] The theoretic basics allows to link and to understand the
paddle glider behavior with its geometrical parameters, direction
and volume of acting forces (especially the tension D). For
consideration we have three the most important dots: O--gravity
center, C--hydrodynamic head center, A--center of tension
application. Also the very important center is the side-stabilizing
center S.
[0043] To find the center of gravity O we can hang the paddle
aqua-glider with string sequentially for the center A then for the
center C. Lines continuing the strings along the keel plane are
crossing at the gravity center O. Distances AO and CO represent
constant eccentricities E and R.
[0044] If the paddle glider moves uniformly and does not change its
angle position then it is in balance state where the vector sum of
all force moments is zero and the vector sum of all forces acting
on the paddle glider is also zero.
[0045] Sum of the forces P and D projections on the axis X is equal
zero, so we have:
P.multidot.sin .nu.-D.multidot.sin .sigma.=0. (1)
[0046] Sum of the projections of forces P and D on the vertical
axis Y, the force gravity G is equal zero:
P.multidot.cos .nu.+D.multidot.cos .sigma.-G=0. (2)
[0047] Because the angle .sigma. and drag force D are supposedly
known (easy measured) then equations 1 and 2 give an expression
finding the angle .nu. of the paddle glider inclination:
tan .nu.=D.multidot.sin .sigma./(G-D.multidot.cos .sigma.). (3)
[0048] After finding the angle .nu. we can find the force P from
the equation 1:
P=D.multidot.sin .sigma./sin .nu.. (4)
[0049] For our example .sigma.=82.5.degree., so sin .sigma.=0.99,
cos .sigma.=0.13. If G=1.5 Kg and D=5 Kg then according the
equation 3 we have tan
.nu.=0.99.multidot.5/(1.5-5.multidot.0.13)=4.2. So
.nu.=76.5.degree. or .nu.=1.337 radians and sin .nu.=0.9728. It
gives P=5.multidot.0.99/0.9728=5.088 Kg.
[0050] Now we can find also the tension deflection angle
.alpha.=.nu.+.sigma.-F. (5)
[0051] In our example F=127.degree.. So
.alpha.=82.5.degree.+76.5.degree.-- 127.degree.=32.degree.. Thus
the paddle glider picture (FIG. 8) should be turned anti clockwise
for 12.degree. additionally because it is depicted originally with
the angle .alpha.=20.degree..
[0052] 4. Collapsibility and Stabilization.
[0053] The paddle glider can be made collapsible (FIG. 1, FIG. 12).
For that its wing 2 and sinker 5 are connected (instead a keel)
with streamlined pillars 14 and hinges 13. Working state is fixed
with the stopper 15 depriving the hinges its mobility. The rear
pillar carries a plate 19 working as a side stabilizer. All others
designs uses the keel 4 also as a stabilizer.
[0054] It is very important that the side pressure center S must be
behind the gravity center O. Otherwise the paddle glider looses
orientation and right direction of gliding.
[0055] 5. Applications.
[0056] 5.1. Propulsion.
[0057] The paddle glider 17 can be used effectively as propulsive
mean in many cases where others can't. For example, rowing a boat
(FIG. 13) in narrow place or in case of emergency. By the way,
because of small size the paddle glider should be used in every
boat as a spare paddle.
[0058] It is not difficult to imagine how a swimmer or an
underwater swimmer can use the paddle glider for accelerating his
swimming. Some times it is more effective than feet flippers. Till
this moment we were powerless when we try to row on an ice floe or
on a raft. The paddle glider is the best solution for this case
(FIG. 14).
[0059] 5.2. Rescue.
[0060] A rescuer uses the paddle glider in fleeing mode operation
(FIG. 15). He repeatedly looses a cord elongating it every time
after pulling taut. When the paddle glider reaches a drowning
person the last one should seize it. The rescuer then pulls it out
off water together with the drowning person.
[0061] 5.3. Special applications.
[0062] The paddle glider can be rigged with different tools
providing additional functionality to it. It can be rigged with a
hermetic light and TV camera (FIG. 16) and be used for survey under
water spaces (FIG. 19) in criminal or industrial cases. Here the
cord should be exchanged with the thin but strong cable delivering
video signal.
[0063] The other application is a flexible remotely acting,
harpoon, hook or a gaff (FIG. 17). Repeatedly pulling the cord a
user bring the paddle glider closer to a floating object. At last
moment when the paddle glider has approached to the object beneath
of it the user should sharply pull cord enforcing the paddle glider
to turn and rise up very fast (FIG. 18). The pike 27 sticks into
the floating object (a log, a shark, a raft etc.). Now the user can
deliver it to him.
