Embodiment
[0048]A rocket-based detonation ramming combined cycle engine, such asFigure 1-3 As shown, it includes a central cone 1, a casing 2, and a tail nozzle 3 connected in sequence. The bottom of the central cone 1 extends into the inside of the casing 2 and is connected to a fixed partition 5. The cone of the central cone 1 The body part and the inner wall of the shell 2 form an adjustable inlet 4, and the shell 2 is provided with a rocket engine 8 and a ring-shaped knocking ram combustion chamber 7 that surrounds the rocket engine 8 in a ring shape. The tail nozzle 3 is connected to the rocket engine 8, the internal passage formed by the blades of the tail nozzle 3 is the rocket nozzle 10 of the rocket engine 8, and the blades of the tail nozzle 3 are connected to the casing 2 The outer ring channel formed by the inner wall of the ram nozzle is a ram nozzle 11. The adjustable air inlet 4, the knock ram combustion chamber 7 and the ram nozzle 11 are connected in sequence, and the fixed p...
