| Abstract: | The technical development of the upper stage and its orbit-control engine at home and abroad is reviewed in this paper.Based on the mission characteristics of YZ-3 upper stage,the technical scheme of 5000 N upper stage engine is put forward,focusing on its ground tests and the first flight application.The development experience of YZ-3 upper stage engine is summarized for the reference of similar rocket engine development.Since the 5000 N upper stage engine of YZ-3 adopts the extruded propellant supply system,orifice injector,regenerative cooling and C/SiC composite nozzle,it has the advantages of simple structure,multiple ignitions,large scale two-way swing.The first application flight was carried on December 29,2018. |
