Abstract

The invention relates to a low-pressure liquefied gas thrust generating method for a spacecraft. According to the method, a specially-designed thrust generating module is adopted to generate thrust and torque for the spacecraft and comprises a storage tank, a first pressure sensor, a charging/discharging valve, a self-locking valve, a thruster, a first temperature sensor and a first heater; the thrust generating module adopts a liquid-storage gas-use working mode, so that pressurized gas is not required to be additionally added into the storage tank, and the supply of a propellant can be driven by only using saturated vapor pressure of liquefied gas; thus, the thrust generating module only needs a liquid charging/discharging valve, and an additional gas charging/discharging valve is not required to be arranged, so that the weight of a system is greatly lowered, and thrust and torque, which have enough accuracy, can be provided for a miniature spacecraft in a microgravity environment and are applied to the attitude control, orbit control or formation flying of the miniature spacecraft.
