Description

technical field [0001] The invention belongs to the field of aviation tests, and in particular relates to an aircraft landing gear aerodynamic load simulation device. Background technique [0002] In the development process of test benches such as Tieniaotai, the aircraft landing gear aerodynamic load simulation device includes two parts: the simulation of the aerodynamic load of the landing gear structure and the simulation of the aerodynamic load of the hatch. The aerodynamic load loading device of the landing gear often becomes an important technical difficulty in the development of the test bench. The design of the aircraft landing gear aerodynamic load simulation device includes accurate simulation of the landing gear loading load, the spatial arrangement of the loading system and other mechanisms, and the transfer of the loading load. At the same time, due to the excessive loading force of the landing gear, the load bearing of the stand is also one of the key elements...
