METHOD FOR THERMAL PROTECTION OF AIRCRAFT STRUCTURAL ELEMENT IN-FLIGHT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC B64C1/38 B64G1/50 

FIELD: machine building; aviation.

SUBSTANCE: device for thermal protection of an aircraft in-flight includes a compressor, nozzles, a tank-capacity, a voltage source, an automatic device for simultaneous connection of a compressor and a voltage source, a protected element of the aircraft design, which is a current-conducting substrate with a heat-insulating coating applied on it in-flight. Nozzle is arranged inside conductive substrate with outlet opening aligned with surface of heat-insulating coating restored in-flight. Nozzle is hydraulically connected in series through tank-capacity of powder of heat-insulating coating restored in-flight with compressor, current-conducting substrate is mechanically connected to anode through layer of electric insulation, anode is electrically connected in series through the voltage source and the current-conducting substrate to the heat-insulating coating restored in-flight. Positive voltage source terminal connected to the anode and the negative – to a conductive substrate. Automatic device for simultaneous connection of compressor and voltage source is in communication with compressor and voltage source.

EFFECT: higher reliability and durability of thermal protection system.
