摘要
气动光学效应是高超音速导弹设计需要解决的关键技术。全面论述了气动光学效应的定量研究方法,包括:小孔径技术、统计方法、随机相位屏方法和涡动力学研究方法,指出了工程上广泛使用的统计方法的适用范围,建议使用大涡模拟方法进行气动光学效应的数值仿真。
Aerooptic effect is the key technology in hypersonic missiles design.The study methods for aerooptic effect are described exhaustively,such as small aperture beam technique(SABT),statistical approaches,random phase screen and eddy dynamics.The limits are presented for statistical approaches widely used in applications.It is suggested that large eddy simulation is applicable for numerical simulation of aerooptic effect.
