Abstract

The invention provides a spacecraft propellant on-track supplementation system. The system comprises a propellant receiving device; the propellant receiving device comprises a pressurized gas reuse unit, a propellant liquid supplemental path unit and a propellant removal blowing unit. The invention also provides an implementation method for propellant on-track supplementation by using the above-mentioned spacecraft propellant on-track supplementation system, and the method comprises the following steps of a gas injection step, a docking step, a leak detection step, a supplement step, a removalblowing step and a separation step. The invention also provides an aircraft, and the aircraft comprises a plurality of propellant receiving devices in the above-mentioned spacecraft propellant on-track supplement system. The propellant receiving devices are provided with storage box pressurized gas multiple reuse functions, and compared with the method of directly discharging the storage box pressurized gas and then conducting propellant supplement, pressurized gas does not need to be supplemented, and propellant supplement cost is reduced.

Description

technical field [0001] The invention relates to the field of space propulsion technology, in particular to an on-orbit propellant replenishment system and implementation method for a space vehicle and an aircraft. Background technique [0002] Patent document CN103950554B discloses a spacecraft propellant on-orbit filling system and method, which adopts the technology of first exhausting and then pressurized filling, but the system provided by this patent document needs to fill the target storage tank The pressurized gas in the system is discharged, and the pressurized gas must be replenished in the subsequent use, which increases the cost of propellant supplementation; moreover, the system cannot realize the functions of simultaneous propellant supplementation and support for the attitude and orbit control engine. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a space vehicle propellant on-orbit...
