Research progress in aero-optical effects of supersonic turbulent shear layers

Aero-optical effects have received increasing attention in recent decades with the continuous development of high-speed missiles’ imaging guidance systems, airborne laser systems, and laser communication systems. Numerous experiments and engineering practices have shown that the aero-optical effects of the supersonic turbulent shear layer can reveal the essential characteristics of general aero-optical effects. Practical engineering problems related to aero-optical effects are often the result of the superposition of the aero-optical effects of multiple shear layers. This paper mainly studies the shear layers represented by the supersonic turbulent boundary layers, mixing layers, and wall jets. The latest research progress on aero-optical effects is summarized to provide a reference for suppressing aero-optical distortion through flow control and adaptive optical correction.
