DEVICE FOR FEEDING A ROCKET ENGINE WITH PROPELLANT

摘要

A device (10A, 10B) for feeding a rocket engine with propellant, the device comprising at least one propellant tank (10, 11), a combustion chamber (18), and a feed pipe (12, 13) extending from the tank (10, 11) to the combustion chamber (18) to feed propellant to the combustion chamber. A valve (14, 15) and a main pump (16, 17) are arranged in succession along the feed pipe. The rocket engine device further comprises at least one branch pump (20, 21, 120, 220) making a branch connection to the tank upstream from the valve in order to feed an auxiliary pipe (22, 23, 122, 222) that serves an auxiliary function of the rocket engine.
