    Abstract

    While high-speed aircraft are flying in the atmosphere, its optical-hood frictions with stream. The dome′s temperature and strain would change with the flight time going, which influences optical transmission because of the variation of the refractive index. The optical dome temperatures and stress-strain conditions varying in the guidance process for different time periods were analyzed. By the method of ray tracing, OPD was calculated, and the result of optical transmission effect through optical image quality and image quality degradation was given. And the result shows that both temperature and speed of aircraft can influence optical transmission heavily.
