Abstract

The invention provides an aircraft test comprehensive climate environment simulation system and a simulation method, and belongs to the technical field of an aircraft test. The simulation system comprises a testing machine, a laboratory structure system and an environment simulation system. The simulation method comprises the following steps: S1, low-temperature environment simulation; S2, high-temperature environment simulation; S3, temperature daily circulation environment simulation; S4, humidity environment simulation; S5, solar radiation environment simulation; S6, rain / wind-blown rain environment simulation; S7, snowfall / snow blowing environment simulation; S8, fog environment simulation; and S9, icing / freezing rain environment simulation. The system solves the problems that an existing experiment facility is generally small in size and relatively single in function, and has the advantages that the functions are complete, all modules work in a matched mode, and the number of devices is reduced.

Description
