载人航天器热控分系统噪声控制

The noise control technology in thermal control subsystem of manned spacecraft

随着载人航天器越来越复杂,热控分系统所用到的高速旋转设备越来越多,所产生的噪声将影响航天员的身体健康,因此载人航天器的噪声控制非常迫切。文章通过热控分系统的布局设计以及单机设备的降噪优化等措施,找到了有效降低整个载人航天器热控分系统噪声水平的方法,可供类似的载人航天项目的热控设计参考。

With the rapid increase of the number of high speed rotation parts in the thermal control subsystem of a manned spacecraft, the noise becomes more and more an important issue. This paper reviews the methods for controlling the noise in the thermal control subsystem of a manned spacecraft, to serve as a guidance for the design of similar spacecraft＇s thermal control subsystems.
