This invention relates to the field of aircraft strength testing technology, and discloses a load reduction device and method for aircraft wing top-mounted strength testing. It utilizes the lever principle to apply a downward load reduction load to the wing to balance the upward top-mounted load borne by the wing top point, thus reducing the overall load on the aircraft to zero and achieving the purpose of load reduction. This invention uses the lever principle to reduce the output load of the hydraulic actuator, achieving small load balancing of extremely large loads. Furthermore, for extremely large single-point loads at a single top point, only a few load reduction load application points need to be applied, reducing the loading channels for the load reduction load and lowering the test complexity. By using the small load of the hydraulic actuator to balance the extremely large load at the top point, the safety and reliability of the test are improved, solving the reliability and safety problems of balancing extremely large single-point loads in wing top-mounted strength testing.

This invention relates to the field of aircraft structural design technology, specifically disclosing an aileron testing device and method for simulating wing deformation. The aileron testing device includes a base, multiple connectors, and multiple drive components. Utilizing this aileron testing device, the drive components move the connectors, which in turn move the aileron joint under test. This simple control process effectively shortens the overall aircraft testing cycle for ailerons. While achieving ground-based bench testing of aileron deformation, it reduces the workload of aileron loading and measurement, simplifies testing complexity, saves testing costs, and shortens the overall aircraft testing cycle.
