用指向性真空規(guī)進(jìn)行空間站結(jié)構(gòu)泄漏監(jiān)測(cè)的設(shè)想

Monitoring Leak of Space Station with Direction Vacuum Gauge

摘要: 文章提出利用指向性真空規(guī)掃描監(jiān)測(cè)空間站艙體漏率的設(shè)想：在空間站艙體外壁上實(shí)驗(yàn)艙和服務(wù)艙的連接處、實(shí)驗(yàn)艙底和對(duì)接裝置的連接處、服務(wù)艙底和對(duì)接裝置的連接處分別設(shè)計(jì)供指向性真空規(guī)運(yùn)動(dòng)的軌道，形成3個(gè)環(huán)行圈，指向性真空規(guī)在步進(jìn)電機(jī)的作用下在各自的運(yùn)動(dòng)軌道上旋轉(zhuǎn)，對(duì)空間站的外部結(jié)構(gòu)進(jìn)行掃描。初步分析了指向性真空規(guī)泄漏監(jiān)測(cè)的靈敏度和定位精度。

Abstract: The environments of a space station during its launch and mission may cause a space station structure leak to put the astronaut in danger and make the equipments fail to work. The idea of monitoring leak of space station with direction vacuum gauge is put forward in the paper, which consists of three circles in the connections of testing cabin and service cabin, below testing cabin and joint, below service cabin and joint, fixed relative to the space station, for the direction vacuum gauges to move by step electromotors and scan the space station’s outside cabin. The sensitivity and location precision of monitoring leak by direction vacuum gauge are analyzed.
