History of a problem
For small aircraft there is a huge scope (transport,
an agriculture, vehicles for supervision, sports,
attractions and many other things). In need for flying vehicles
for these areas try to fill with the help of small aircraft (planes and
helicopters),
motor-glider and
motor-paraplanes, vehicles of vertical take-off and landing (VTOL), But these
vehicles have low efficiency and a small maneuverability. It is extremely
important, that these vehicles could fly of vertical
take-off and landing. Small planes,
motor-glider and this operation cannot execute
motor-paraplanes. Helicopters can vertically fly up and hang on a place, but
have very small profitability. Numerous attempts to create
vehicles with vertical rise and lag on a place are now done. But these
vehicles have very low profitability and do not manage
to create confidently flying vehicle.
Principal cause of that till now is not possible to
create the economic VTOL, is
use of classical stationary aeromechanics.
At performance
of orders for aviation technics there was a practice, that in customers causes
trust not that executor who investigated much (and knows high technologies much),
and what shows breadboard models of flying vehicles (which
badly fly, but this executor promises to receive in the future high
characteristics). As a result of this practice, every year in the world hundreds
flying and not flying svehicles which do not show
improvement of their characteristics are created.
My rate in development of the
vehicle is done on our knowledge of nonlinear oscillatory aerodynamics,
development of the vehicle on the basis of uniform
oscillatory system and application of adaptive control systems. For preparation
for creation of vehicles on such basis it is spent
about 35 years (instead of creating 35 years unnecessary
vehicles on the basis of blind imitation birds, not understanding their
physics of flight that is done till now all over the world). I use knowledge of
hundreds scientists of the foscillations which have
deposited money in research in liquids, mechanics of flight and
swimming of animals, in oscillatory mechanics and
control systems, in bionics and power of vortex.
We undertake to develop and construct a hang-glider or a paraplane much more
economic, maneuverable, including with vertical rise and lag on a place.

Vehicles
can be three variants:
1.
Motoparaflapping.
It is a motor-paraplane creating lift and
thrust with the help flapping
working elements (KNOW HOW).
Advantages in comparison with traditional VTOL:
- Vertical rise, lowering and vertical
take-off and landing;
- Decrease in aerodynamic drag;
- More lift;
- It is less capacity of the engine;
- Better controllability at small speeds;
- Safety (contact with a wing is safe, the protective protection is not
necessary);
- Sharply appeal of the vehicle improves.
2. A
motor-glider with a flapping tail wing (instead
of the screw the flapping wing is established).
Advantages in comparison with traditional
motor-hang-gliders:
- Sharply appeal of the vehicle improves.
- Aerodynamic drag of the pilot and the engine
is reduced due to creation of a wave flow with the help of "gratuitous" energy
from losses oscillatory thruster.
- Thrust increases due to increase
effective area of thruster, without increase
vectorially the areas;
- Capacity of the engine decreases;
- The length of start decreases;
- Controllability increases at small speeds (due to use of a
flapping wing as a rudder);
- Safety (contact with a wing is safe, the protective protection is not
necessary);
- Sharply appeal of the vehicle improves.

We
search for the investor for creation of new type over effective flying
vehicles.
We can develop and make the first working samples of flying
vehicles of various purpose. We have no ready samples.
We have the big theoretical, experimental and practical experience of
development and manufacturing of working samples of the technics using
oscillations.
Now a great attention is paid to the
development of MAV with flapping wings. At the same time a highly economical
and movable MAV with flapping wings has not been made. There are a number of reasons
of this failure:
1. The theory and general
principles of designing these vehicles have not been developed. In
developing these vehicles birds and insects are blindly copied.
2. The mechanics of induced lift and
thrust has not been studied enough. Now a mode
of quasistationary oscillating aerodynamics is used resulting in low economical
MAV. Numeric computations on the basis of the Navier-Stokes equations are used.
But these works do not yet have atlases
(data bases) of aerodynamic characteristics of oscillating wings. Besides, the Navier-Stokes
equations are not an adequate mathematical model of an oscillating body
aeromechanics.In experimental research only some specific
aspects of the phenomenon are investigated and not the whole situation.
3. MAV are designed as vehicles working on the
principles of commom stationaty mechanics. Due to this mistake, MAV have low
cost-effectiveness and a high level of harmful oscillations and vabrations.
4. The MAV wings are copied from planes or from
birds or insects wings. Scientists and designers do not understand
internal functions of the insects wings and birds feathers. One of internal
functions is the transmission of mechanical energy and its coordination with a
wing aerodynamic load (as well as the provision of an optimal trajectory of
wing elements).
5. The necessity to have special transmitting
and coordinating elements between an oscillation drive and a wing is not
considered. That
results in low energy-efectiveness and a high level of harmful oscillations and
vibrations.
6. There
are no control systems adequate to the MAV engine-thruster complex
specifications.
7. Energy sources, engine and oscillation
drives are poorly suitable to MAV with flapping wings. MAV
can have by far better energy and movement characteristics than MAV of a plane
or helicopter type. To develop a highly effective MAV the following steps
should be taken:
1. To research and design MAV on the basis of a
single oscillation system.
2. To use the modes of non-linear oscillation aerodynamics
to obtain lift. For example, the effect discovered by
R. I. Vinogradov – a manifold increase in a thruster (a flapping wing) effective
aerodynamic surface in certain oscillation modes.The use of these modes can allow to obtain
lift and thrust several times higher in comparison with that in the mode of
quasistationary oscillation aerodynamics. This factor in its turn may lead to
the lowering of required engine capacity and therefore, to reducing the size
and weight of all the MAV units.
3. To use wave flow of MAV motionless units to
lower drag and to produce additional lift and thrust. Wave flow is the Jukovski-Knoller-Betz effect.
It is flow distribution caused by a flapping wing. To
produce wave flow additional energy is not required.
4.A
specific computer system for adaptive optimal control of the MAV engine-thruster
complex should be developed. This system is designed for an automatic control of the MAV engine-thruster
unit characteristics to obtain a maximum performance index, or a minimal
aucustic noises level, etc.
5. An oscillation drive, transmitting units and
a wing should be developed as a unified oscillation mechanical system. It is possible to combine several functions in
one element (an engine, a transmitting unit and a wing).
Mav with flapping wings can have considerable commercial
prospects, allowing to develop small-size and large effective flying vehicles
of a new type. To develop MAV an international cooperation of various specialized
companies and scientists is required.
