The invention discloses a vacuum pipeline spaceflight launching tail section air pressure balancing device and method. The device comprises a pipeline built along a mountain, a vehicle is arranged inthe pipeline, a rocket is carried on the vehicle, a pipeline outlet is located in the top of the mountain, and a plurality of vent holes are formed in the pipeline close to the outlet; the pipeline iscomposed of a starting section, an accelerating section and a launching section, and the starting section, the accelerating section and the launching section are each provided with a vacuum pump. A first air gate is arranged between the starting section and the accelerating section, a second air gate is arranged between the accelerating section and the launching section, the starting section is provided with an inlet door, the launching section is provided with an outlet door, and the tail end of the launching section is provided with a plurality of vent holes which are controlled by an automatic air valve to be communicated with the atmosphere; according to the device, huge airflow impact caused by pressure difference when the rocket rushes out of the vacuum pipeline is eliminated at lowvacuum environment loss cost, and the spaceflight launching safety of the vacuum pipeline is improved.

    一种真空管道航天发射末段气压平衡装置与方法,包括依山体而建的管道,管道内设有车辆,车辆上搭载有火箭,管道出口位于山体顶部,管道靠近出口设有多个放气孔;所述的管道由始发段、加速段和发射段组成,始发段、加速段和发射段分别设有真空泵;始发段和加速段之间设有第一气闸门,加速段和发射段之间设有第二气闸门,始发段设置入口门,发射段设置出口门,发射段末端设有多个放气孔,放气孔通过自动气阀控制其是否跟大气连通;本发明以较少的真空环境损失代价,消除火箭冲出真空管道时由于压差带来的巨大气流冲击,提高真空管道航天发射安全性。
