THERMIONIC METHOD FOR THERMAL PROTECTION OF AIRCRAFT Russian patent published in 2016 - IPC B64D33/08 H01J45/00 F01P9/00 F02K1/82 

FIELD: aviation.

SUBSTANCE: thermionic method for thermal protection of parts of aircrafts (AC) includes removal of heat flow of AC heated part to less heated by heat emission by module arranged on inner surface of heated AC parts electrically conducting material or coating having high electron emission at heating-emitter, unit with gap from the emitter-collector electrically conductive element, on which is deposited emitted electrons and through on-board self-contained electric power consumer is transported to emitter with subsequent sealing, evacuation formed between emitter and collector cavity and introduction of chemical elements or compounds, which reduce work function of electrons.

EFFECT: invention is aimed at reduction of heat-stressed state of AC engine parts.
