摘要:

红外罩材料包括红外罩增透保护膜和基底材料, 是高速导弹结构--功能一体化的关键部件, 应用极为广泛. 但是, 红外罩材料通常工作于恶劣的外界环境下, 处于复杂的热力混合作用状态, 可能导致窗口失效, 因此对红外罩材料热力响应和失效的研究具有重要的科学研究价值和工程实际意义.本文针对高速飞行器环境下红外罩材料的气动热力失效机制, 从典型材料的特性及制备、气动热力响应机理及分析、红外罩材料的结构性和功能性失效等方面总结相关学者的研究成果, 并对今后的发展趋势进行展望.

Abstract:

As one of the key components of a high-speed aircraft, the infrared window which is composed by matrix materials and functional films is widely applied. In the harsh environment, however, the infrared window works under complex aerothermal conditions, which may lead to its structural failure or dysfunction. Thus, the investigation on the aerothermal dynamic failure of infrared window in high-speed aircraft is of scientific importance and practical significance. This article reviews the studies on the aerodynamic thermal failure mechanisms of infrared windows in high-speed conditions, concerning typical materials, the aero-thermo-dynamics and structural failure or dysfunction. Finally, the prospects of further investigations on infrared windows are discussed.

Key words: infrared window, aerothermal dynamic, failure mechanism
