The invention discloses a collimation structure for a gas trapping device and an implementation method thereof. The collimation structure comprises a collimator main body connected with a gas trapping device main body, the collimator main body is a hollow tubular telescopic assembly, and a pipeline of the collimator main body is parallel to the flowing direction of air molecules; the length of a gas trapping flow channel formed by the collimator main body and the gas trapping device main body is adjustable, the collimator main body is connected with a control system of a spacecraft, and the collimator main body forms a plurality of narrow and length-adjustable gas trapping flow channels so as to reduce the escape rate of gas; the control system preliminarily sets the initial length of the collimator main body according to the predicted flight environment, and the control system automatically adjusts the length of the collimator main body according to the real-time flight environment when the spacecraft flies in the space so as to obtain the gas trapping efficiency for providing proper thrust for the spacecraft. The target gas trapping efficiency is obtained by adjusting the length of the collimator main body, and the most suitable thrust is provided for the flight of a spacecraft.

    本发明公开了一种气体捕集装置用准直结构及其实现方法,包括与气体捕集装置主体连接的准直器主体,准直器主体为空心管状的伸缩组件,准直器主体的管道与空气分子的流动方向平行,且准直器主体与气体捕集装置主体组成的气体捕集流道的长度可调,准直器主体与航天器的控制系统连接,准直器主体形成多条狭窄且长度可调的气体捕集流道以降低气体的逃逸率;控制系统根据预测的飞行环境初步设定准直器主体的初始长度,且控制系统根据航天器空间飞行时的实时飞行环境自动调整准直器主体的长度以获得为航天器提供合适推力的气体捕获效率,本发明通过对准直器主体的长度进行调节以获得目标气体捕集效率,为航天器飞行提供最合适推力。
