Paper Abstract

With the development of aerospace technology, the demand for solar simulation technology is getting higher and higher. The realization of solar simulation technology mainly has the following two ways: solar simulator and solar irradiation lamp array. The main applications of solar irradiation arrays are in the fields of aerospace, automobile and vehicle, material performance testing, agricultural breeding, etc. Compared with solar simulators, the structure is simple, economical and has a large irradiation area. The Beijing Institute of Satellite Environmental Engineering has successfully developed a single-sided wall vertical arrangement lamp array. The successful irradiation area of Xi'an JiaoTong University is 2.0m*1.5m, the irradiation is 1000w/m2, and the unevenness is better than ±5%. Lighting system. This design meets the requirements of thermal flow simulation of military aircraft cabins, improves the accuracy of heat flow simulation, and establishes a set of high-power radiation simulation devices. Through design simulation, it can be seen that the irradiation area of this heat flow simulation irradiation system can reach 1500mm*3500mm, at work. Within 1m, the irradiation energy is continuously adjustable from 0.8 to 1.5sc, the maximum radiant energy can reach 1.8sc (1sc=1353w/m2), and its uniformity can reach ±6.7%. The device can be used for aerospace components of the sun. Irradiation environment simulation test, etc.
