摘　　要：介绍了北航D4风洞发展的一套具有同步测控技术的张线支撑系统,该系统较好地解决了运输机后体气动特性研究中模型支撑与其气动干扰之间的矛盾。从功能上该张线支撑系统分为控制子系统与测量子系统两部分。首先,该张线支撑机构通过两个步进电机进行驱动,所以需要控制子系统对两电机进行同步控制,从而实现对试验模型迎角的精确控制。其次,该张线支撑机构的测量子系统实现了与北航D4风洞测压、测力、PIV等数据采集系统的联动,通过与控制子系统进行网络通信,可以进行在迎角序列下的同步测量,从而可以大幅度提高试验效率。最后,利用该张线支撑系统,在北航D4风洞进行了运输机后体流动特性的风洞试验研究,结果表明该张线支撑系统满足试验要求。In order to resolve the conflict between model support and its aerodynamic in the aerodynamic study of transport afterbody, wire suspension system useing synchronous measurement and control technology is developed which is applied in D4 wind tunnel of Beihang University. Functionally, the system is divided into two parts, control subsystem and measurement subsystem. Control subsystem synchronously operate the two motor which dive the wire suspension structure, then the AOA of experimental model can be accurately adjusted. And synchronous measurement has been realized between the control subsystem and the measurement subsystem, such as the pressure measurement system, the balance measurement system and the PIV system. On this basis, the wire suspension system is applied to the test of transport afterbody in D4 wind tunnel. As a result, the wire suspension system satisfies the experimental requirements.
