METHOD OF FIXED BALLOON POWER SUPPLY AND DEVICE TO THIS END Russian patent published in 2012 - IPC B64F3/02 B64B1/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Method of supplying fixed balloon onboard electrical equipment consists in that, with fixed balloon at definite altitude and failure of ground electric power supply, onboard electrical equipment is switched over to supply from onboard storage battery. Control signal is generated for onboard electrical equipment to switch it over to reduced electric power consumption. In ''on-ground'' position, onboard electrical equipment is supplied from ground power source its voltage being converted in DC voltage corresponding to operating voltage of onboard equipment. Proposed device comprises ground electric power, protection and switching hardware, first converter, winch with cable-rope laid on its drum, second onboard converter and onboard storage battery making standby power supply of onboard equipment. Second converter is provided with extra power input, output voltage transducer and control input. First converter is provided with extra conversion unit with power output with ground supply cable. Note here that with balloon in ''on-ground'' position, ground supply cable output end is connected to second converter extra power input. Output of voltage transducer is connected via control output is connected to control inputs of onboard electrical equipment.

EFFECT: higher efficiency of electric power transmission.
