Abstract

The invention relates to the field of aircraft high-lift system tests, in particular to a high-lift system whole-aircraft loading dynamic test method, so as to solve the problem that test results of the high-lift system design at present are incorrect. The high-lift system whole-aircraft loading dynamic test method loads an aerodynamic load on aerofoils of a high-lift device under the condition of a predetermined angle step by step through a loading actuator, judges whether a fault recurs during the process of loading the aerodynamic load to a limit load step by step under the predetermined angle so as to obtain magnitude of the loading load when the aircraft fails, can truly simulate the real flying condition of the aircraft high-lift system, confirms that the stress conditions of the high-lift system, the relevant high-lift device, wing boxes and the like in whole-aircraft tests are consistent to that of the same in the air, and eliminates major flight failures of the aircraft; in addition, the high-lift system whole-aircraft loading dynamic test method is a breakthrough of the dynamic driving/coordinated loading technology, and changes the severe shortages and deficiencies of the previous test methods essentially.

Description

technical field [0001] The invention relates to the field of aircraft high-lift system testing, in particular to a dynamic test method for full-aircraft loading of the high-lift system. Background technique [0002] In the past high-lift system tests, due to the limitations of design ideas, the motion function inspection test of the high-lift system was only loaded on the wing box and the fuselage without loading the high-lift device; at this time, the high-lift system driving the high-lift device was basically at The unloaded conditions are completely different and unreal from the actual flight conditions. Such a test cannot test the influence of the design and manufacturing process of the aircraft's high-lift system, and there are great hidden dangers in the aircraft flight test. Since the follow-up loading system of the full-stroke increasing lift device is very expensive, it has not been used in previous aircraft static tests. Thus, for newly developed aircraft, there ...
