Combined type thrust vector spraying pipe system and projectile body with system

Abstract

The invention belongs to the technical field of power of aerospace aircraft, in particular to a combined type thrust vector spraying pipe system and a projectile body with the system. Two sub-systemsincluding a liquid secondary ejection system and a supersonic separation line swinging spraying pipe are organically combined, so that the advantages of both of the sub-systems are fully developed, and the liquid secondary ejection system mainly has the characteristics of quick response, high efficiency and light structural weight, and also can play a role in lubrication and cooling of a sprayingpipe, so that the aircraft has a larger thrust vector deflection angle and higher response speed. According to the combined type thrust vector spraying pipe system disclosed by the invention, the carrying amount and the box storage size of liquid injecting agent of the aircraft can be reduced, and the total weight of the thrust vector control system is effectively controlled. Due to injection of the injecting agent, heating of an internal molded surface of the spraying pipe can be alleviated, the ablation resistance capability of the spraying pipe is enhanced, and granule phase is prevented from entering a separation line gap to prevent the spraying pipe from being stuck. Because of lubrication components added in the injecting agent, friction of a sealing ring also can be reduced, and thereliability of the system is further improved.

AI Technical Summary

Problems solved by technology

This method can produce thrust vectoring to a certain extent, but this method will increase the weight of the engine, and it will also increase the weight of the engine

At the same time, due to the complex mechanical structure of this method, the reliability of this kind of thrust vectoring device is low, and the cooling requirements are higher in high temperature and high pressure environments.
