SYSTEM AND METHOD FOR FEEDING AT LEAST A BOOSTER MOTOR, AND ELECTRICALLY-DRIVEN FEED PUMP WITH HIGH FREQUENCY VARIABLE RELUCTANCE ACTUATOR

摘要

The invention concerns a system and a method for feeding with liquid propellant at least a booster motor (1) of an air or space craft. An electronic device (12) receives the liquid derived from a pressurised main tank (2), and a secondary tank (13) of variable volume less than that of the main tank is adapted to receive the liquid supplied by the electrically-driven feed pump (12) and to feed the booster motor(s) (1). An automatic control (18) enables to trigger the electrically-driven feed pump (12) at a pressure Pa prevailing in the secondary tank (13).
