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. |
