The invention provides an air inlet passage test efficient large-size ejection pipeline device, belongs to the technical field of wind tunnel testing, and aims at solving the problem that the actual air inlet passage flow cannot be achieved by completely relying on wind tunnel inflow stamping. A flowmeter, a flowmeter rear diffusion segment, a flowmeter rear stable segment, a flow regulating valve, a regulating valve rear stable segment, a regulating valve rear diffusion segment, an ejector front stable segment and an ejector are connected in turn and arranged on the same axis to form a path, and the overall pipeline is installed at a wind tunnel center. According to the air inlet passage test efficient large-size ejection pipeline device, the flow meeting the requirement of the air inlet passage installed at the front end of the pipeline can be generated under the ejection effect of high pressure gas so that high flow simulation of the air inlet passage wind tunnel test can be realized.
Description
technical field [0001] The invention relates to an injection pipeline device, in particular to an efficient and large-size injection pipeline device for an air inlet test, and belongs to the technical field of wind tunnel tests. Background technique [0002] As the interface between the internal flow and the external flow of the aircraft, the performance of the air inlet directly affects the joint performance of the aircraft and the engine. The air inlet is designed by the aircraft model unit, focusing on the loss of the air inlet under the design flow rate and the stability of the dynamic distortion parameters. Surge boundary, etc. These parameters are generally obtained and verified through wind tunnel tests in the aircraft design stage. Inlet wind tunnel tests usually use a single inlet test method without an engine, and completely rely on the incoming flow of the wind tunnel to reach the air intake. The actual flow of the inlet passage needs to be pumped to simulate the ...
