Abstract: In order to use the same wire-driven parallel suspension system to implement static and dynamic derivative experiments in low-speed wind tunnels, a survey of the research work addressing the wire-driven parallel suspension system with eight wires (WDPSS-8) projects is presented in this article. The research methodology combines both theoretical and experimental aspects. The results show that, there are some unavoidable drawbacks, such as the interference of the streamline flow brought by the strut in the traditional suspension system. Moreover, cablemounted systems are suitable for experiments of the static derivatives of the aircraft; however, they cannot be used in the experiments of dynamic derivatives; WDPSS-8 can be successfully used in experiments of static derivatives, and it has the potentiality to be used in experiments of dynamic derivatives. The issues in the theoretical aspect have been addressed. However, much work has to be done in the experimental aspects.
