Thermal-optical Analysis for Optical Window under High Mach Flight condition

摘要：

When the airborne platform, where installed the optical window, is in high Mach flight condition. The aerodynamic heating effect, which will influence optical properties of optical window, becomes very obvious. This special flight condition will change shape, refractive index and also refractive index distribution of optical window due to the generated high axial temperature gradient. To ensure image quality of aerial remote sensor, the present paper does thermal-optical analysis for optical window under high Mach flight condition. Then, on this basis, do simulations according to theoretical analysis and boundary conditions derived from practical assumptions in order to get the final conclusions.
