超音速状态下整流罩红外窗口的选型问题研究

Determination of the Dome Infrared Window in the Supersonic Mode

作为超音速状态下整流罩红外窗口玻璃，应具有优良的光学性能、机械性能、化学性能和热性能。从实际工程应用出发，介绍了该状态下红外窗口玻璃的选型及制作方案。

The dome infrared window used in supersonic mode should possess the excellent proper- ties of fine optical. mechanical, chemical and heat proof. Several kinds of crystal were compared. Re- search and experimental results shows ZnS polystal with a anti-reflection film is fit for pratical use.
