SUPERSONIC ROTARY ROCKET Russian patent published in 2019 - IPC F42B15/00 

FIELD: aviation; astronautics.

SUBSTANCE: invention relates to aerospace engineering, namely, to aircraft with air-jet engines moving with supersonic speeds. Device comprises a cylindrical housing with a channel inside. This channel consists of confuser forming convergent cavity, which is used as ramjet air-jet engine. There are also nozzles for spraying fuel and control device. Cavities are formed between walls of housing, confuser and detonation combustion chamber. They are filled with fuel. All rocket surface in contact with air uses heat from aerodynamic heating, converting fuel into gaseous state. Detonation combustion chamber is made as a guide device for rocket rotation. Inner volume of chamber is divided by hollow partitions of specified curvature, which form sections in number N, where N = 1, 2, 3… natural numbers to provide required rpm of rocket, compression of fuel and air. In each section of the detonation combustion chamber slit-like nozzles are installed for spraying of gaseous fuel and compressed air, equipped with check valves.

EFFECT: technical result is increased reactive thrust, increased thermal protection of rocket, heat recuperation from aerodynamic heating into engine body and improved controllability of rocket.
