“神舟号”载人飞船开伞控制方案设计

载人飞船的开伞控制方案是回收着陆系统设计中的一个关键环节,它直接关系到飞船回收着陆系统工作的成败。文章根据载人飞船特点的分析,制订了飞船开伞控制方案,即采用静压高度控制法来控制开伞,然后根据静压高度控制的工作原理,详细介绍了开伞控制方案的设计方法和流程。仿真试验和飞行试验结果表明:"神舟号"载人飞船开伞控制方案的设计是合理的、正确的。

The Control Scheme Design of Parachute Deployment for SHENZHOU Manned Spaceship

The control scheme of parachute deployment for manned spaceship is a key part of the recovery and landing system design,it directly affects the success or failure of the recovery and landing system.Through analyzing the manned spaceship characteristics,the control scheme of parachute deployment is established,which is the statical pressure altitude control method.Then according to the principle of the statical pressure altitude control,the design method and program are introduced in detail.The results of simulation and flight tests show that the design of the control scheme of parachute deployment for SHENZHOU manned spaceship is reasonable and right.
