FIELD: aviation.
SUBSTANCE: invention relates to power plants of aircraft. Ramjet engine (RJE) and turbojet engine (TJE) arranged in parallel are proposed. Compressed air is partially withdrawn from TJE and supplied to receiver and then to combustion chambers of vortex gas compressor (RJE), jets of which are introduced at acute angle to axis, which creates negative pressure along the RJE axis and displacement of gas medium with acceleration towards the nozzle. RJE is equipped with its own annular conical combustion chamber. Preliminary compression of air on the front part is performed by flat spatulate nose, i.e. is common air intake.
EFFECT: vortex gas compressor provides compressed air supply to ramjet engine at launch and all flight modes and obtaining maximum specific thrust.
