STARTING SYSTEM OF A RAMJET ENGINE Russian patent published in 2023 - IPC F02K7/12 

FIELD: rocketry.

SUBSTANCE: used in the power plants of aircraft (LA), using atmospheric oxygen as an oxidizer. The system for starting a ramjet engine is made on a detachable frame containing an outer spherical surface, the diameter of which is equal to the diameter of the cylinder of the combustion chamber constant section outlet, while the detachable frame is attached to the combustion chamber body by a fixing device containing a fuel line for supplying the calculated amount of fuel for launch and structural elements that block the fuel supply to the launch system at the time of operation. The separation of the frame and the release of the combustion chamber from the engine starter is ensured by the simultaneous supply of pressure from any source to the piston drives of the locking devices, which release the frame fastening. Moving the frame with a spherical surface along the cylindrical body of the combustion chamber ensures its shock-free separation from the aircraft.

EFFECT: ensuring the preservation of a stationary combustion regime throughout the entire combustion chamber channel at a supersonic flow rate, simplification of the engine start device and improvement of the mass-traction characteristics of the aircraft as a whole.
