摘要：

In this paper, a wire-driven parallel suspension mechanism for two aircraft models in formation flight is designed to simulate the flight motion in a limited space channel with obstacles around it in wind tunnel test. Taking the helicopter as an example, based on the working condition parameters, the double wire-driven parallel mechanisms are designed as the support of the aircraft model, and the kinematic model of the helicopter for cooperative motion between the movable pulley suspension point and the helicopters in formation flight is established. Furthermore, the static stiffness of the system is analyzed, and the influence of rotor rotation on the dynamic stiffness of the wire-driven parallel suspension system is verified by experiments. Additionally, the algorithm of interference between the wire and the wire, the wire and the model in the process of two aircraft models in formation flight simulated flying and landing in the limited space channel is given, and the interference analysis of the wire structure of the support mechanism is carried out. The results show that the support mechanism designed in this paper can effectively solve the support interference problem for two aircraft models in formation flight in the limited space channel, and the system stiffness meets the stability requirements of the low-speed wind tunnel test, making it an effective solution for aircraft model formation flight test in low-speed wind tunnel. © 2019, Press of Chinese Journal of Aeronautics.
