【 摘 要 】

Considering the requirement of rocket engine restart on the liquid propellant location, this paper dedicates to the simulation research on sinking movement of liquid propellant in space vehicle. The extrusion, thrust and structural types of liquid propellant management for space vehicle are summarized. The numerical simulation and drop tower test are compared to study how the liquid propellant moves in the gravity environment, and the relationship between the sinking time and flight acceleration for a new-type space vehicle are provided. These results have considerable significance for the liquid propellant management and acceleration design of space vehicle.
