Abstract

According to the requirement of aircraft test mission, a set of radiant heat simulation system which can be used in complex extreme environment is developed in this paper. The system is mainly composed of optical subsystem, mechanical structure, cooling subsystem and control subsystem. The design process of this system mainly includes optical system design, mechanical structure design, cooling system design, control system design and environmental adaptability design. The radiant heat simulation system needs to ensure the normal operation under the extreme environment of low pressure (5kPa), high humidity (90%RH), high temperature (75°C) and low temperature (-20°C). In order to solve this difficulty, the system developed a special light source protection cabin. The protection chamber can provide normal temperature, normal pressure and low humidity working environment for the light source. With the help of cooling system and control system, the environment adaptability of radiant heat simulation system is ensured effectively. After the development of the radiant heat simulation system, six indexes including irradiance, spectrum, illumination area, irradiation uniformity, irradiation stability and environmental adaptability were evaluated according to the test standards. At present, the radiant heat simulation system has been involved in part of the aircraft test, the effect has been recognized by the test department.
