Thermal adaptability analysis and thermal design of a multi band airborne optoelectronic equipment

Thermal adaptability is an important part of the aerial optoelectronic equipment to adapt to the working environment. In this paper, the parameters and working conditions of an electro-optical equipment are introduced, and the thermal adaptability is analyzed with the optical design. According to the heat transfer theory, combined with the actual conditions of the equipment, the thermal design is carried out. The temperature distribution in 6 hours is obtained by simulation analysis. The results show that the thermal design is suitable for the actual working conditions of the existing equipment, and the maximum temperature difference between the primary and secondary mirrors at any time is 4.2°C, which meets the requirement of the maximum temperature difference of 5°C.
