“天宮一號”目標(biāo)飛行器檢漏工作總述

Summary of leak testing work for Tiangong-I target spacecraft

摘要: 文章主要描述了“天宮一號”目標(biāo)飛行器研制過程中與檢漏相關(guān)的內(nèi)容，包括檢漏項(xiàng)目、檢漏方法和檢漏結(jié)果等。重點(diǎn)介紹了氦質(zhì)譜吸槍檢漏、壓力變化檢漏和氦質(zhì)譜非真空累積檢漏及多種氣體分析等多種檢漏方法及其適用范圍。“天宮一號”的檢漏數(shù)據(jù)驗(yàn)證了應(yīng)用以上檢漏方法可行且有效。

Abstract: This paper reviews the leak testing in the development of the experimental module of the Tiangong-I target spacecraft, including the leak testing items, the leak testing methods and the leak testing results. Stresses are put on the following three methods, namely, the helium mass spectrum with sniffer, the pressure leak testing, and the helium mass spectrum with cumulation in a non-vacuum container. The leak testing results of Tiangong-I's experimental module validate the feasibility and the effectiveness of each method applied in different leak detection items.
