Description

The distributed atmospheric engine dynamic and static pressure of a kind of helicopter testing apparatus
Technical field
The invention belongs to airplane equipment field tests, relate to the distributed atmospheric engine dynamic and static pressure of a kind of helicopter testing apparatus.
Background technology
The distributed atmospheric engine dynamic and static pressure of traditional helicopter testing apparatus element is relatively backward, is not easy to operation.In the time carrying out pitot-static pressure pipeline air-tight test, due to the pitot interface size difference of each model helicopter, be furnished with respectively special dynamic and static pressure testing equipment, increase production cost, extend the lead time of this test unit, versatility is poor.
Simultaneously, the dynamic and static pressure pipeline outlet of the distributed atmospheric engine dynamic and static pressure of traditional helicopter testing apparatus has connected respectively a non-removable flexible pipe, due to the distributed atmospheric engine of helicopter and ground distance larger, this flexible pipe is about 10 meters, after test, this flexible pipe is exposed to testing apparatus outside, be unfavorable for equipment to deposit and be exposed to outer flexible pipe very easily damaged, do not meet our requirement attractive in appearance for modern testing apparatus simultaneously.There is the dismounting of being not easy to, inaesthetic shortcoming.
Summary of the invention
Technical matters to be solved by this invention is: the distributed atmospheric engine dynamic and static pressure of helicopter that a kind of convenient disassembly is quick, versatility is good testing apparatus is provided.
Technical scheme of the present invention is: the distributed atmospheric engine dynamic and static pressure of a kind of helicopter testing apparatus, comprise wobble pump, hand-operated direction valve, static line, dynamic pressure pipeline, airspeed indicator and climb meter, it is characterized by: described testing apparatus also comprises gas inspection fixture and flexible pipe; Described static line outlet is equipped with the outlet of dynamic pressure pipeline the quick-release socket with retaining valve is housed respectively; On two static pressure interfaces of described gas inspection fixture and a dynamic pressure interface, the quick-release plug with retaining valve is all housed; Quick-release plug and quick-release socket are equipped with in described flexible pipe two ends; Static line is connected with gas inspection fixture by flexible pipe with dynamic pressure pipeline.
Further, between described wobble pump and hand-operated direction valve, connect by quick-release plugs and sockets.
The invention has the beneficial effects as follows: the structure that the distributed atmospheric engine dynamic and static pressure of helicopter of the present invention testing apparatus adopts quick-release type socket and plug to coordinate in dynamic and static pressure pipeline exit, realize device external coupling assembling and equipment body part convenient disassembly is quick, can change when being necessary the gas inspection fixture in external module, have stronger versatility; And after the dismounting of the coupling assembling of device external, can leave equipment body inside in, make this testing apparatus outward appearance succinct, attractive in appearance.
