Development of liquid propulsion technology for reusable launch vehicle
Reusability is the technological development trend of launch vehicle in the future,and it is an effective way to reduce the cost of space launch and achieve large-scale space launch.This paper summarizes the development status of vertical take-off and vertical landing reusable launch vehicle power technology at home and abroad.The full mission process of rocket launch and recovery using aerodynamic deceleration and power deceleration was discussed,and the characteristics of power technology of reusable launch vehicle were summarized.The key technologies including wide-range inlet pressure multi-start technology,large-scale rapid and high-precision thrust regulation technology,fault diagnosis and health monitoring technology and maintenance technology were analyzed and so on.
