The novel gas collecting device comprises a rotary side wing and a gas suction spray pipe, a gas inlet and a gas outlet are formed in the two ends of the gas suction spray pipe respectively, the radius of the gas inlet is larger than that of the gas outlet, and the rotary side wing is arranged at the position, close to the gas inlet, of the inner wall of the gas suction spray pipe; one end of the rotary side wing is connected with the air suction spray pipe, and the other end of the rotary side wing is inclined towards the air outlet and forms an included angle beta with the length direction of the air suction spray pipe. The device is simple in structure, the number of particles moving in the forward direction can be increased to a great extent through the change effect of the rotary side wings on air flow in the air suction spray pipe, the air collection rate of the device is improved, and the rotary side wings are not contradictory with existing strategies of adding diamond cones, adding front-end grid meshes and the like; a plurality of optimization strategies including rotary side wings can be adopted at the same time, and the collection rate of the air suction device is increased through superposition.

    本发明提供了一种新型气体收集装置与吸气式电推进系统,包括回转侧翼与吸气喷管,吸气喷管的两端分别设置进气口与出气口,进气口的半径大于出气口的半径,回转侧翼设置在吸气喷管的内壁靠近进气口处;回转侧翼的一端连接吸气喷管,回转侧翼的另一端朝向出气口倾斜设置,回转侧翼与吸气喷管的长度方向之间存在夹角β。本发明结构简单,通过回转侧翼对吸气喷管内气体流动的改变作用,可以极大程度增加正向运动粒子的数量,提升装置的气体收集率,且回转侧翼与现有的“添加菱形锥体”、“添加前端栅网”等策略并不矛盾,可同时采用包含回转侧翼的多种优化策略,叠加提升吸气装置的收集率。
