摘要
随着各种飞行器对信息获取的精确性和实效性依赖程度的大幅度提高,采用光学成像探测技术和追求高速飞行已成为各种飞行器发展的趋势。光学成像制导飞行器在大气层内高速飞行时,光学头罩与来流之间发生剧烈的相互作用,光学头罩与来流之间形成复杂的流场,在光学窗口中产生复杂的热响应,给头罩内的光学成像探测系统带来气动热辐射噪声,带来目标图像的偏移、抖动、模糊等气动光学效应。文中针对高速飞行器成像探测面临的气动光学效应,从机理、工程和应用三个层次,提出了气动光学研究思路和后续工作展望,旨在为气动光学效应研究提供参考思路。
Abstract
With the increasing dependence on the accuracy and effectiveness of information acquired during flight, the photoelectric image detection and hyper-speed flight technology have become the development trend of the future flight vehicles. However, when the flight vehicles equipped with optical imaging detection and guidance system fly at high speed in the dense atmosphere, the optical dome and incoming flow generate a complex flow filed because of intense interaction. The complex thermal response generated in optical windows brings aerodynamic thermal noise for the optical imaging detection system in the optical dome, and causes deviation, jitter, blur of the target, which is called aero-optical effect. From three levels——mechanism, project and application, research ideas and further works were put forward for aero-optical effect faced by the imaging detection system of high speed fight vehicle, aiming at providing reference ideas for study on aero-optical effect.
