Research on the Influence of Optical Lens Arrangement on Aerodynamic Characteristics of Airborne Optical Window
In order to reduce the impact of aerodynamic load on the airborne optical window and explore the influence of the optical lens arrangement on the aerodynamic characteristics of the optical window, three optical windows with different optical lens arrangements are designed in this paper. Through the dynamic numerical simulation analysis of these optical window models, the influence of different optical lens arrangements on the aerodynamic characteristics of the optical window is studied, and the model with the least air resistance and the best aerodynamic characteristics is obtained. According to the model′s wind resistance under 0° angle of attack, the simulation analysis of model′s structural mechanics characteristics is carried out. The results show that the optical window model will not be damaged by impact under the wind resistance load, and meets the requirements of rigidity and strength.
