摘要
在归纳、分析国内外近３０年大飞机全模试验技术研究的基础上，提出了选择支撑的原则，扣除支撑干扰的关键。建立了一套完整的试验技术、支撑干扰修正方法。该支撑系统新颖独特，能广泛用于不同布局的大飞机纵、横向试验，支撑干扰小并可以有效扣除，可连续改变攻角，运转灵活、装拆方便，支撑强度、刚度良好，安全可靠。可推广应用于单独角支撑不适宜的场合；也可应用于其它高速风洞中。
Based on the summary and analysis of complete model wind tunnel test technique both in and out of China during nearly thirty years,this paper presents the criterion for selecting medel support system and the method for correcting its interference.The model support system presented in this paper is a newlydeveloped one suitable forthe longitudinal and lateral experiments for large aspect ratio aircraft models with different configurations.The system is characterized by its small interference and easy correction,continuous change of angle of attack, smooth running, easy assembling, high stiffness and strength,reliability and safety. It can be used in high speed wind tunnels when a single sting support system is not suitable.
