A new wire-driven parallel support system for wind tunnels to suspend a 1:40 scale model of F-15E is stated. By this design, the ranges of pitch, roll and yaw angles of the scale model at the home pose are all -90deg ~ 90deg. Then, the kinematics and statics of the system are studied, and a dynamic model of the system is established. Based on the model, the tracking control of the attitude change of the scale model during a wind tunnel test is studied, and a motion control scheme in the task-oriented coordinates is proposed because it is necessary to obtain accurate attitude angles of the scale model and also it is easy to attain more precise positioning by using external sensors such as cameras to measure the posture of the scale model. The feedback linearization control is designed. Finally, a simulation is made, and the results show that the proposed control scheme is powerful
