摘　　要：针对型号研制的风洞试验需求,在2.4m跨声速风洞中开展了多功能支撑系统试验技术研究,研制了一套多功能支撑系统。该支撑系统既可实现定侧滑角连续变迎角的试验方式,又可实现定迎角连续变侧滑角的试验方式。在0.6m跨声速风洞开展了引导性试验研究,并在2.4m跨声速风洞中对该支撑系统与传统的支撑方式进行了风洞试验对比。结果表明,多功能支撑与传统支撑方式的风洞试验数据相关性良好,表明该支撑装置的研制是成功的,可应用于型号试验。A test technique research for versatile support system was conducted in the 2.4 meter transonic wind tunnel. Applying this system in wind tunnel test could be implemented in a manner of continuously changing sideslip angle at a constant attack angle besides continuously changing attack angle at a constant sideslip angle. Introductory investigation on versatile support system was conducted in 0.6 meter transonic wind tunnel. Test applying for the versatile support system in comparison with traditional system was conducted in the 2.4 meter transonic wind tun nel. Results indicated that test data obtained with two different support systems presented a good correlation, and the design of versatile support system was successful.
