Problems solved by technology

However, the realization of the large-scale rudder surface hinge moment test device does not enlarge the simple size ratio of the conventional large-scale rudder surface hinge moment test device. In the conventional large-scale rudder surface hinge moment test, the rudder surface deflection, but the weight of the large-sized rudder surface is very heavy, and it cannot be lifted by manpower. It is not feasible to realize the deflection

Description

technical field [0001] The invention belongs to the technical field of aircraft wind tunnel tests, and relates to an aircraft rudder surface device for aerodynamic tests, in particular to an aerodynamic test device for measuring large-scale rudder surface hinge moments. Background technique [0002] In the process of aircraft R&D and design, it is necessary to conduct wind tunnel hinge moment tests on various rudder surfaces such as flaps, ailerons, elevators, and rudders to obtain the variation law of the rudder surface hinge moment parameters and master the aerodynamic performance of the rudder surface. The measurement accuracy of the rudder surface hinge moment wind tunnel test results plays an important role in supporting the maneuverability of the aircraft and the design of the control system. [0003] However, in order to reduce the test cost and shorten the test period, the rudder surface hinge moment wind tunnel test usually uses a wind tunnel test device with a larg...
