We have long-term experience
in research of non-stationary hydrodynamical modes of oscillation. The
carried out researches have allowed to establish the following
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
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
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
- 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.
