高速飞行器热流固耦合光传输分析
Thermal-Fluid-Solid Coupling Optical Transmission Analysis of High Speed Aircraft
摘要
Abstract
In the aerodynamic environment, the inhomogeneous refractive index field formed by the effect of thermal-fluid-solid coupling between optical dome and flow field will seriously interfer the optical transmission.Firstly, the parameters distribution of flow field is obtained by solving Navier-Stokes equa-tions, and the thermal-fluid-solid coupling analysis for optical dome is done.Then, the optical transmis-sion path from the target to the detector is simulated by light tracing method, and the optical path differ-ence (OPD) is calculated.Lastly, the effect on image quality is analyzed by image quality evaluation functions.The result shows that the effect of refractive index field on optical transmission increases and the image quality of optical system declines seriously with the increase of speed.关键词
