Description
Technical field
The present invention relates to a kind of injection piping installation, and in particular to a kind of efficient large scale injection pipeline dress of air intake test
Put, belong to wind-tunnel technique field.
Background technology
Air intake duct directly affects the cooperation of aircraft and engine as stream in aircraft and outflow interface unit, its performance
Performance, air intake duct are designed by aircraft type unit, pay close attention to loss of the air intake duct under design discharge, steady dynamic distortion ginseng
Number, stall margin etc., these parameters are general by wind tunnel test acquisition and checking in the airplane design stage, and air intake duct wind-tunnel is tried
Test, generally the actual stream of air intake duct is not reached flowing punching press using without the independent air intake test mode of electromotor, fully relying on wind-tunnel
Amount, simulating Flow Field In An Inlet, injector is used as a kind of fluid conveying being widely used in the draw inlet road that need to take measures
Device, has more application in terms of simulation Flow Field In An Inlet, and in air intake duct wind tunnel test, injector is arranged in pipeline,
Composition injection pipeline, produces the air intake duct necessary flow met installed in pipeline front end under the ejector action of high pressure gas；Existing
Partial-air admission road test pipe-line system, by pipeline size limitation, flow simulation ability can not meet big flow air intake test
Demand, if the whole wind-tunnel pipe-line system of transformation, will pay larger cost, aspiration will install effusion meter, Flow-rate adjustment in addition
The devices such as valve, circuit design are slightly unreasonable, and line loss will be caused to be increased dramatically.Accordingly, it would be desirable to a kind of wind-tunnel air intake test
Efficiently large scale injection piping installation, to meet air intake duct necessary flow, improves air intake test ability.
Content of the invention
It is an object of the invention to provide a kind of efficient large scale injection piping installation of air intake test, to solve because of air intake duct
Underfed and the problem of big flow simulation test can not be carried out.
