Description

technical field

[0001] The invention relates to the technical field of aircraft testing, in particular to a pressure imbalance emergency processing system for aircraft testing and a processing method thereof. Background technique

[0002] As a large-scale carrying facility for aircraft environmental tests, the climate and environment laboratory can accommodate full-size aircraft and can provide all-weather, time-independent high temperature, low temperature and other environmental conditions. The engine start-up environment simulation is to simulate the low temperature, high temperature, humid heat and other climate environments encountered during the start-up or operation of the aircraft engine in the climate environment laboratory. The environment laboratory must be equipped with an air compensation system and an exhaust gas emission system. Due to the ground driving test in the engine laboratory, the amount of air consumed is huge. If there is a delay in the dynamic resp...
