The variable cycle propulsion mechanism has a propulsor (1) carrying gas products escaping through a tube creating a thrust, and an auxiliary propulsion unit (14) separate from the propulsor. The auxiliary propulsion unit operate for subsonic flights, land...

The variable cycle propulsion unit has a propulsor (1) with a compressor and an auxiliary propulsion assembly (12) generating a complementary thrust. The complementary unit has a propulsion relay tube (20) from the main propulsor providing additional thrus...
