COOLING SYSTEM OF HIGH-SPEED AIRCRAFT INSTRUMENTATION COMPARTMENT Russian patent published in 2020 - IPC B64C1/38 B64G1/50 

FIELD: aviation.

SUBSTANCE: invention relates to liquid cooling of machines and engines and can be used for provision of thermal mode of instrument compartments of high-speed aircrafts. Technical solution extends only to cooling systems of unsealed hardware compartments of high-speed aircrafts during autonomous flight in the stratosphere for several tens of minutes with intensive aerodynamic heating of aircraft skin to 1200 °C. Alcohol-water evaporative cooling system of instrument compartment consists of heat-insulating housing of instrument compartment with mirror screen, spongy evaporator from foamed polyurethane, nozzles of injection of coolant, reservoir with coolant, start-up pyrolysis valve and capacity of supercharging with nitrogen. Improved thermostatic control of instrumentation of instrument compartments of aircraft, reduced volume and reduced weight of cooling system.

EFFECT: higher reliability.
