Abstract

In recent years, the demand for optical imaging and detection in hypersonic aircraft has been on the rise. The high-temperature and high-pressure compressed flow field near airborne optoelectronic devices creates significant interference with light transmission, known as hypersonic aero-optical effects. This effect has emerged as a key technological challenge, limiting hypersonic optical imaging and detection capabilities. This article focuses on introducing the thermal effects and optical transmission effects of hypersonic aero-optical effects, as along with corresponding suppression techniques. In addition, this article critically reviews and succinctly summarizes the advancements made in hypersonic aero-optical effects testing technology, while also delineating avenues for future research needs in this field. In conclusion, there is an urgent call for further exploration into the study of aero-optical effects under conditions characterized by high Mach, high enthalpy, and high Reynolds number in the future.

带薄膜冷却的高超音速光学窗口的航空光学效应研究进展。

近年来，高超音速飞机对光学成像和探测的需求不断增加。机载光电器件附近的高温高压压缩流场会对光的传输产生严重干扰，即所谓的高超音速航空光学效应。这种效应已成为一项关键的技术挑战，限制了高超音速光学成像和探测能力。本文重点介绍了高超声速气光效应的热效应和光传输效应，以及相应的抑制技术。此外，本文还对高超音速气动光效应测试技术所取得的进展进行了批判性回顾和简明总结，同时也为该领域未来的研究需求指明了方向。总之，未来迫切需要进一步探索高马赫、高焓和高雷诺数条件下的气动光效应研究。
