Abstract

A wide-thrust-adjusting-range mixed-mode ionic liquid propelling system comprises a supercharged powder grain tank and the like; the downstream of the supercharged powder grain tank is connected withone end of a self-locking valve LV1, the other end of the self-locking valve LV1 is connected with one end of a supercharged gas capacitor, the other end of the supercharged gas capacitor is connectedwith one end of a pressure sensor PT1 and one end of a self-locking valve LV2, the other end of the self-locking valve LV2 is connected with one end of a filter F1, and the other end of the filter F1is connected with one end of a charging and discharging valve MV1, one end of a pressure sensor PT2 and one end of a mixed-mode ionic liquid propellant storage box; the other end of the mixed-mode ionic liquid propellant storage box is connected with one end of a charging and discharging valve MV2, one end of a pressure sensor PT3 and one end of a filter F2, and the other end of the filter F2 isseparately connected with one end of a self-locking valve LV3 and one end of a self-locking valve LV4; and the other end of the self-locking valve LV3 is connected with a chemical thruster, and the other end of the self-locking valve LV4 is connected with an MEMS electrospray thruster. The problem that an existing single propelling system cannot simultaneously meet comprehensive requirements for large thrust, high precision and small thrust is solved.

Description

technical field [0001] The invention belongs to the technical field of mixed-mode liquid propulsion, and relates to a mixed-mode ionic liquid propulsion system and method. Background technique [0002] When the micro-nano satellite group works together, the rapid maneuvering orbit change during the networking period requires the engine to provide a large thrust (0.1 N to 1 N level), while the precise position and attitude control during the long-term operation requires high-precision small thrust (micro Newton level to millinewton level), the existing on-board propulsion system / module cannot meet these two requirements at the same time. [0003] Existing solutions need to provide two or more sets of propulsion systems to meet the needs of different thrust levels, which will bring a greater burden on the mass and volume of the entire on-orbit operation system. In addition, for different propulsion methods, a certain amount of propellant needs to be configured in advance. In ...
