Known electrodynamic aircraft, containing a high-voltage source of electrical voltage, two electrodes, one of which is executed in the form of a thin straight rod, the other in the form of systems consisting of separate elements interconnected electrically, and the power source [U.S. Patent No. 3187206, NCI 310-5 (analog)].

These very promising devices - energy saving, but without the energy recharge their operational capability is limited, and therefore, the time of their stay in space is also limited.

Known systems of power supply of aircraft, containing a receiving antenna for receiving microwave energy emitted from a terrestrial source, the Converter of this energy into the energy of direct current, the mind is ogical voltage and switch [microwave ENERGY.

The coefficient of transmission of microwave energy using a parabolic antenna with a diameter of up to 30.5 m is not more than 18% when the transmission distance is 22 feet Therefore, the use of such a channel is expensive and unprofitable.

The most cost-effective of the claimed invention is a power supply system of the aircraft electrodynamic apparatus containing ground source of microwave energy and transmitting antenna form the energy into a narrow beam receiving antenna on an aircraft, inverter microwave energy to the energy DC [microwave ENERGY.

Brown. P.77-88 (prototype)].

The disadvantage of this system is the need to create a receiving antenna on an aircraft large area to extend the service life in the air, but a large area of the receiving antenna generates a large vetrano pressure on the system, and to stabilize its position is the need for additional energy. In addition, the receiving antenna should be focused in the direction of the radiating antenna.

The essence of the invention lies in the fact that in the power supply system of the aircraft electrodynamic apparatus containing ground source of microwave energy with the means of its radiation and aircraft of oval form with controls and flight control apparatus placed under the dielectric casing of the apparatus, and inverter microwave energy into electrical energy DC entered the shell of aluminum foil, secured by a continuous layer on the outer surface of the dielectric cladding apparatus and inverter microwave energy is made of material representing equal proportions of the mixture of two chemical semiconductor components with different atomic numbers, together forming the dipole semiconductor matrix, this mixture is made by granulation of not more than 30...50 microns and deposited in the form of a coating solid layer thickness in 2...3 times bigger than the size of granule components on the surface of the shell, with like poles of the dipole matrix interconnected and connected to the corresponding terminals of the management and control of flight of the device,

The advantage of the proposed technical is the first solution is a simple design of the power supply system, allows to extend the presence of the device in the air long flight. The continuity of the power contact of the transmitting and receiving antennas, regardless of the orientation of the device in space can increase the efficiency of the system due to developed effective surface of the receiving antenna and Converter.

The shell 5 or gluing the Ute to the casing 4, or put it another way.

Semiconductor Converter 6 performs the function of simultaneously receiving antenna and transmitter of microwave energy into the energy of DC.

The Converter 6 is made of a semiconductor of a mixture of the two semiconductor components with a grain of not more than 30...50 microns each. One of the components has an atomic number greater than the atomic number of the second component. As components can be, for example, materials gallium (Ga31with atomic number 31 and arsenic (As33with atomic number 33 or other couples: gallium - antimony; cadmium - tellurium, etc. the combination of the two semiconductor components allows you to automatically ensure dipole rectifier matrix, the positive and negative poles of the charges which are connected with the corresponding terminals of the control mechanism and control regime of the flight apparatus 3. This mixture is applied in the form of a coating on the surface of the shell 5, for example, by plasma or flame spraying thickness of about 2...3 times bigger than the size of the grains granulation components. The coating process mentioned methods does not violate the structure of the material of the shell 5, as experience shows that these methods can be used for coating any material, even on the paper backing.

Having sex is provodnikovogo Converter 6 provides efficient conversion of microwave energy into the energy of direct current, and the shell 5 of aluminum foil allows you to increase the power conversion of microwave energy 1.75 times due to direct transmission of microwave energy through a transformer 6 and the reverse passage of microwave energy through a transformer 6, reflected from the material of the shell 5 [see str analogue].

The specified material properties of the shell 5 and inverter 6 together increase the efficiency of the system.
