Design and Study on Mechanical Properties of Aircraft Wing Lift Simulation Device

摘要

Full scale aircraft drop test was an effective method to assess dynamic loads and response in indoor environment. Wing lift simulation with drop testing machine is to impose a dynamic load equaling the landing weight on the aircraft, so as to completely simulate the landing condition. The choice of loading mode and amplitude is the critical factor for drop tests of aircraft. This paper proposes a wing-lift loading system suitable for full scale aircraft drop test. The principle of this loading system is first introduced. The proposed wing lift loading system is validated using quasi-static and dynamic tests. Wing lift loading mode and criterion are proposed based on the experimental results. Finally, the proposed loading method and system is applied to a full scale aircraft drop test, experimental results confirm the validity of the feasibility of the loading method and the proposed wing lift simulation system.
