HYPERSONIC AIRCRAFT EQUIPPED WITH COMBINED POWER UNIT AND METHOD OF ITS OPERATION IN FLIGHT Russian patent published in 2023 - IPC B64C30/00 B64D27/02 B64G1/14 

FIELD: supersonic aircraft.

SUBSTANCE: hypersonic aircraft equipped with a combined power plant includes two turbojet engines using aviation kerosene as fuel and one turbojet engine using cryogenic fuel as fuel. The aircraft is equipped with kerosene fuel tanks (4) and cryogenic fuel tanks (5), fuel lines for supplying kerosene to the engines (6) and fuel lines for supplying cryogenic fuel to the engines (7), respectively. The power plant is designed with the ability to bring the engine in flight, using cryogenic fuel, to the maximum thrust mode and with the ability to accelerate the aircraft to hypersonic speed with its total thrust impulse and then maintain this speed until the end of the hypersonic flight segment. Cryogenic fuel supply pipelines are distributed near the outer surface of the front parts of the airframe (12) of the aircraft and the target load compartments.

EFFECT: reliable cooling of the aircraft airframe when flying at hypersonic speeds and a reduction in aircraft weight are achieved.
