Abstract

The invention relates to a constant flow air supply device of an aircraft environment control test system and a control method, and belongs to the technical field of aircraft environment control system test design. The device comprises an air compressor, an air storage tank, an automatic regulating valve, a controller, a pressure sensor, a manual regulating valve and an environmental control test system, one end of the air compressor is connected with the air storage tank; the air storage tank is connected with the environmental control test system through a pipeline; an automatic regulating valve, a pressure sensor and a manual regulating valve are arranged on the pipeline; and the controller is respectively connected with the automatic regulating valve and the pressure sensor. Compared with an existing manual adjustment means, the constant flow air supply device for air supply of the aircraft environment control test system can achieve automatic flow adjustment, and manpower cost is saved.

Description

technical field [0001] The invention relates to a constant-flow air supply device and a control method for an aircraft environment control test system, and belongs to the technical field of test design of an aircraft environment control system. Background technique [0002] During the simulation test of the aircraft environmental control system, a large-flow air supply with a flow rate of hundreds or even thousands of kilograms per hour is often required. Under such a large-flow air supply condition, the pressure of the air storage tank also fluctuates frequently. Due to It is difficult to purchase a constant flow device under such a large flow in the market. Therefore, during the test of the environmental control system, the flow can only be adjusted by manually adjusting the opening of the valve. With the pressure consumption and replenishment of the gas storage tank, the pressure of the gas source changes at any time, and manual adjustment of the flow will consume a lot o...
