Abstract: Firstly, the wire-driven parallel support system is presented. Secondly, the designing principle of the support systems in a low speed wind tunnel is investigated according to the experimental requirement of a vehicle model. Under the principle, the detail of the design about a new kind of redundantly restrained positioning mechanisms with 8 wires, WDPSS-8, is presented to suspend the 1∶40 scale model of F-15E. By this design, the ranges of pitch , roll and yaw angles of the model at the home pose respectively are -79°~71°, -90°~90°, -38°~39°. Finally, based on the systematic dynamics model, a position control scheme in wire length coordinates applying an actuator torque controller is proposed to implement the attitude control of the model. Moreover, the motion stability is proven by a Lyapunov function.
