The invention discloses an aircraft climate environment test environment temperature adjustment control method, comprising: 1. Starting the engine of the test aircraft to run at a slow speed; The ambient temperature is lowered so that the ambient temperature in the test area is in the range of -20°C ~ +50°C; 3. The first high-temperature level regulation subsystem and the second high-temperature level regulation subsystem are activated at the same time, and the embossed climate environment laboratory Lower the temperature of the test environment in the test area, so that the ambient temperature in the test area is in the range of -30°C to -5°C; 4. Simultaneously enable the first high-temperature stage regulation subsystem and the cascade regulation subsystem, and the convex climate environment experiment The temperature of the test environment in the room is lowered so that the ambient temperature in the test area is within the range of -55°C to -15°C. The invention is applicable to various climate test working conditions, and improves the automation degree and integration degree of the regulation and control system operation.
Description
technical field [0001] The invention belongs to the technical field of aircraft climate environment tests, and in particular relates to a method for adjusting and controlling the temperature of an aircraft climate environment test environment. Background technique [0002] At present, the temperature range that the convex-shaped climate environment laboratory needs to achieve is +74°C~-55°C. Within the range of +74°C~-55°C, the process of temperature from high to low belongs to the cooling process. The holding stage after the target temperature requires cooling supply. For the convex-shaped climate environment laboratory, the cooling capacity required in the process of cooling down and maintaining low temperature comes from the huge volume of indoor air, ground and enclosure structures, test pieces, indoor heat sources and leakage cooling. The demand for cooling capacity depends on the test conditions. Different test conditions have different cooling capacity requirements. ...
