Underwater vehicles with thruster oscillatory type
We have long-term experience in research of non-stationary
hydrodynamical modes of oscillation. The carried out
researches have allowed to establish the following qualitative differences
thruster the oscillatory type working in a
non-stationary mode, from thruster working in a mode
of stationary hydrodynamics:
1. The effective hydrodynamical area can be
in several times more, than the area drawn a wing. As a result of it, with other
things being equal, the efficiency of thruster of
oscillatory type will be more, than screw or hydro-jet type.
2. Thruster of oscillatory type, brings
indignations of the certain type in a stream which is flowing round the case of
the underwater device. Owing to it, a flow of the case occurs to a
small variable corner which under certain conditions creates
thrust. This force will reduce the general hydro dynamical
drag of the case, even up to zero (This idea was
stated by N.E.Zhukovskiy, Knoller,
Betz, Katcmauer.,
W. Shmidt and we have confirmed it experimentally). On
this process it is not required to
additional energy from thruster.
3. Using two above-stated in items 1 and 2 effects which prove only in the
certain area of non-stationary oscillations, it is
possible to create thruster oscillatory type, which
will be much more effective (more efficiency, less hydro dynamical
drag and a level of acoustic noise), than the best traditional
thruster.
4. High efficiency thruster
should be supported in navigation with the help of special
adapting control systems (such program and a control system on the basis
of the microprocessor is created by us).
Advantages of
engine-thruster complex of
oscillatory type:
- Weight reduction
of the engine and fuel, increase of speed of navigation of the device;
- Accordingly
increase of weight of a commercial cargo;
- Decrease in engine and fuel cost;
- Decrease in
cost prices of transportation of a commercial cargo (cost of a kilometer-ton);
- Seaweed, networks
and other subjects are not reeled up on thruster;
flapping thruster is safe for the human and sea
animals.
Realization of works
is expedient for carrying out in two stages:
1. Creation and test pass underwater
vehicles with remote control.
Purpose of these devices is:
- Check of hydro dynamical modes and
improvement of constructive units of a drive and a control system, for the
subsequent use on underwater vehicles;
- Mini underwater vehicles
have an independent field of application in various areas.
2. On the basis of the received experience
samples thruster oscillatory type for underwater
vehicles, the surface ships and underwater robots are
created. Graham Hawkes (President, Hawkes Ocean Technologies
http://www.deepflight.com) has created a series of fine underwater vehicles
similar to planes. These vehicles have the form of the
case, wings, an arrangement of various rudders and elements
which surprisingly approach for installation on this vehicle
thruster oscillatory type. Then this underwater
vehicle could look like it is shown below:
We search for the investor for creation of
new type highly
economic and maneuverable underwater
vehicles with thruster
oscillatory type.
We can
develop and make the first working samples of engine-thruster a complex of
oscillatory type for underwater vehicles of various
purpose. We have no ready samples. We have the large
theoretical, experimental and practical experience of development and
manufacturing of working samples of engineering using oscillations. |
