AIRCRAFT THERMAL PROTECTION DEVICE Russian patent published in 2018 - IPC B64C1/38 B64G1/50 

FIELD: aircraft; rocket engineering.

SUBSTANCE: invention relates to aircraft and rocket engineering and can be used to provide thermal mode for the on-board equipment of super- and hypersonic aircraft (AC). Aircraft thermal protection device is made in the form of an outer and an inner shells and contains a coolant impregnated cooling material. Cooling material is placed onto the outer surface of the inner shell and is made in the form of segments located along the entire surface of the shell with gaps not less than the value of thermal expansion of the segment material under the effect of the heat flux from the outer shell. At the rear end of the device, in the direction of the aircraft flight, there are openings for removing the coolant vapor through steam lines into a cavity of the aircraft unpressurised compartment, which is not subject to the influence of the external ram-air flow.

EFFECT: technical result of the invention is to reduce weight-dimensional characteristics of the device and to simplify the design.
