THE ALTERNATIVE HELICOPTER WITH MINIMUM POWEREXPENDITURES

The existing flying devices, are heavier than air, fly up at the expense of a lifting force created by circulation of a stream of air relatively to bearing planes, on what the plenty of energy is expended. The mankind went on a path of the force decision of a problem, having decided a problem of flight at the expense of overgrowth of power of onboard power plants, and has created in essence devourers of kerosene. The figures speak for themselves, for example, the onboard power plant spends 1 kW of power on creation of 20 kg of a lifting force, at the helicopter 1 kW on creation of 4-7 kg of a lifting force is spent. The path, chosen by the person, on the decision of a problem of flight is a deadlock, it has exhausted itself.

The analysis of principles of creation of a lifting force has allowed to approach to the decision of a problem nonconventionally, having taken for criterion a maximum of a lifting force at minimization of the costs of energy. The new principle is worked, the accounts are executed confirming a correct solving of a problem, made breadboard models indicate a possibility of creation of a rotor, capable to develop a lifting capacity in 100-250 kg at the costs of power of 1 kW. The principle of operation of such bearing rotor is based on jet force of dispersed air with recuperation of energy expended on creation of speed of air on the cut of nozzle.

The idea of the know-how consists that the selection of power at a jet current of air after an output from nozzle and return of obtained power on the shaft of a drive is carried out without any axial response, and the torque is generated only in a horizontal plane. Let, for example, the carrying capacity forms at section of nozzle is S = 10 m², speed of the outflow from nozzle V_c » 100 m/s, specific gravity of air g = 1,2 kg/m³, factor of compression of a jet j = 0,85, acceleration of a free falling g = 9,81 m/s² and has the following magnitude:

R_kg = (j • V_c² • g • S) / (2 • g) = (0,85 • 100² • 1,2 • 10) / (2 • 9,81) = 5199 kg.

Thus the power is expended:

W = 0,5 • S • V_c³ • g • (1/h_c - 2 • h_r),

where h_c - efficiency of the compressor = 0,98;

h_r - efficiency of the recuperation » 0,508.

Then:

W = 0,5 • 10 • 1003 • 1,2 • (1/0,98 - 2 • 0,508) » 26,46 kW.

R_kg/W = 5199 / 26,46 = 196,5 kg/kW.

Having placed such rotor on the existing helicopter instead of its bearing screw and having added servo-drivers for change of an inclination of a rotor relatively to a vertical axis, we shall receive the extremely economic flying device, on a maneuverability not making a concession to the helicopter, and on carrying capacity, economy of fuel, cruising speed considerably exceeding all kinds and types of modern helicopters.

Increasing efficiency of the recuperation, it is possible to reach stunning results on profitability. Actually new helicopter can be created for 6 months with concrete binding to any existing type of the helicopter.

The payment of the know-how makes US $10 million, creation of the first experimental sample with the engineering specifications and flight tests - US $1million.
