- Abstract:
- High-performance miniature liquid bipropellant rocket engine has the characteristics of rapid response, low specific impulse, high control accuracy, light weight and small size, which can provide technique basis for micro satellites to realize accurate orbit attitude control and prolong orbital lifetime. Taking the 5 N miniature bipropellant rocket engine as an example, the progress and achievements in design and preparation of the miniature liquid bipropellant rocket engine in Shanghai Institute of Space Propulsion are overviewed, such as micro injector design, micro valve design, micro-component molding technology and thermal compatible design. The development plan of this research project is given in this paper.
