航天器交会对接是指两飞行器通过对接机构形成一个整体,完成航天员在轨驻留、上行货物等任务。文章主要以货运飞船系列航天器与空间站系列航天器对接后形成的对接通道为研究对象,开展地面模拟试验方法研究,解决了对接通道泄压所需的背景真空环境模拟、对接通道内气体压力与温度准确测量等难题,充分验证了对接通道的泄复压性能以及在轨保压检漏方法的可行性。
Rendezvous and docking of the spacecraft means that the two aircraft form a whole body through the docking mechanism to complete the astronauts’ stay in the orbit and uploading goods. The main research object is the docking channel formed after the spacecraft series of spacecraft and docking spacecraft are docked. The ground simulation test method is studied to solve the background vacuum environment simulation of docking channel relief. The gas pressure in docking channel and Accurate temperature measurement and other problems, fully verify the docking channel venting pressure performance and in-track pressure test leak detection method is feasible.
