Wing lift simulation with full scale aircraft drop test is to impose a dynamic load on the aircraft wing in indoor environment, so as to completely simulate the landing condition of the aircraft. The wing lift is critical index for full scale drop tests of aircraft. In this paper, the simulation criterion of wing lift for full scale aircraft drop test is given, and a method for simulating wing lift loading is proposed. According to the method, the design principle of the wing lift simulation device is introduced, and the mechanical performance of the wing lift simulator is carried out. The method and the device are applied to the full scale aircraft drop test of a certain aircraft. From the four aspects of the simulation of the wing lift, the attitude of the aircraft, the sinking speed and the energy absorption of the landing. And the simulation method of the wing lift of the full scale drop test is validated and evaluated. The test results shows that the method is suitable for simulating the lifting force. And can be used for full scale aircraft drop test.
