The invention provides an aircraft air inlet static test suction load loading device and belongs to the aviation structure static test design field. The aircraft air inlet static test suction load loading device is used for controlling the magnitude of the suction load of an aircraft air inlet static test. The aircraft air inlet static test suction load loading device includes a vacuum pump which is adopted as a main suction device of the aircraft air inlet static test, a vacuum tank group, a stamping stage which is connected with an air inlet, the vacuum pump and the vacuum tank group through conduits, a first control valve which controls the air inflow of the vacuum tank group for the air inlet, a second control valve which controls the air inflow of the vacuum pump for the vacuum tank group, and third control valves which control the air inflow and air outflow of the vacuum tank group. According to the aircraft air inlet static test suction load loading device provided by the invention, the vacuum tanks are additionally arranged in the test equipment, and the vacuum space of the vacuum tanks can be utilized, so that the suction capacity of the test equipment can be indirectly improved, and the performance of the vacuum pump can be compensated, and the test equipment can satisfy high test requirements.
Description
technical field [0001] The invention belongs to the field of static test design of aeronautical structures, and in particular relates to a suction load loading device for a static test of an air intake passage of an aircraft, which is used for controlling the magnitude of the suction load of the static test of an air intake passage of an aircraft. Background technique [0002] With the development of ultra-high sound number aircraft, the load situation of the air inlet of the aircraft becomes more and more complicated. Among them, the design situation of the suction load of the inlet has been close to or reached the vacuum state, that is, the suction load of -101kPa. During the static test of the aircraft inlet, due to the limitation of the sealing conditions of the inlet, as well as the suction capacity and power limitations of the existing test equipment, the test process is difficult to meet the requirements of the test load and test speed. [0003] Based on the technica...
