首先扼要分析了航天器中容器利用轨道真空环境进行排行的特点,结合流体力学原理分析了简单容器的圆孔和短管的排行初期和后期的物理过程,理论计算得出了容器内气压和排气流量随时间变化的规律。讨论了航天器中容器排气产生的推力对航天器姿态、微重力水平的干扰情况。给出了相应的数学判据,并且认为减小容器内的初始气压和初期排气管的管径、采用多管对称排气以及将这种推力作为主动控制力加以利用是碱小排气推力干扰的有效办法,最后总结出了一些基本的工程设计原则。
First of all, the characteristics of vessel alignment in space environment of the spacecraft are briefly analyzed. Combined with the fluid mechanics principle, the initial and late physical processes of the circular holes and short tubes of the simple vessel are analyzed. The pressure and row in the vessel are calculated theoretically Air flow changes with time. The interference of spacecraft thrust and spacecraft attitude and microgravity is discussed. The corresponding mathematical criteria are given and it is considered that reducing the initial pressure in the vessel and the diameter of the initial exhaust pipe, using multi-pipe symmetrical exhaust gas, and utilizing this as an active control force is a small exhaust thrust The effective method of interference, finally summed up some basic principles of engineering design.
