A combined thrust vectoring nozzle system and projectile with the system

Abstract

The invention belongs to the technical field of aerospace vehicle power, and in particular relates to a combined thrust vectoring nozzle system and a projectile with the system. The present invention organically combines the two sub-systems of the liquid secondary injection system and the supersonic separation line swing nozzle, and fully utilizes the advantages of both. The liquid secondary injection system mainly has the characteristics of fast response, high efficiency, and small structural weight. At the same time, it can also lubricate and cool down the nozzle, so that the aircraft has a larger thrust vector deflection angle and faster response speed. The invention can reduce the carrying amount of the aircraft liquid propellant and the volume of the storage tank, so that the total weight of the thrust vector control system can be effectively controlled. The spraying of the propellant can slow down the heating of the inner surface of the nozzle, enhance the anti-ablation ability of the nozzle, and prevent the particle phase from entering the gap of the separation line and causing the nozzle to be stuck. The lubricating components added in the propellant can also reduce the friction of the sealing ring, further improving the reliability of the system.
