- 高性能、轻质量、小尺寸的上面级动力系统可以为整个任务节省更多的质量和空间,从而增加有效载荷的质量。提出了一种基于差动气动增压装置的多次启动姿轨控一体化动力系统,动力系统由主发动机系统、姿控发动机系统、一体化供应系统等组成。该动力系统的系统级试验验证结果表明:姿控发动机与主发动机可通过共用贮箱实现推进剂的一体化供应; 主发动机采用差动气动增压装置的多次启动方式,多次启动能力提高到20次以上,多次启动加速性(T90)缩短到3 s以下。该系统技术可实现上面级动力系统的高度集成化,提高整体性能。
- Abstract:
- The more weight and space for the whole flight mission will be economized by use of the dynamical power system of upper stage with the characters of high performance,light weight,small size,while the weight and scale of other payloads will be increased. The turbopump-feed dynamical system integrated with the orbit and attitude control is composed of the main engine,engines for attitude control,and the integration assemblies. The system-level test results of the dynamical power system show that:firstly,it can be realized that the integrated supply of the propellant to the attitude control engines and the main engine through sharing the main tank; secondly,the main engine should be multi-started more than 20 times by use of a pneumatic supercharger to pressurize the propellant for the generator; finally, the time spending on start-up acceleration(T90)can be reduced to less than 3 s. That the high integration of the propulsion system of the upper stage can be realized and the overall performance can be improved by use of this integrated system technology.
