摘　　要：翼/舵等部件在转动条件下热结构/匹配/密封考核一直是高超声速飞行器研制阶段的技术难点,以前该类考核基本采用高超声速验证器在飞行条件下直接考核。基于该地面考核难题,在电弧风洞上开展了相应的试验技术研究,针对如何建立流场、解决流场堵塞、转动条件下流场控制等技术问题提出了相应的解决方案,并成功应用于转动部件热结构、热匹配及热密封试验中,结果表明:试验模型表面热流分布与飞行条件下较为一致,转动过程中流场稳定,在国内首次实现了高超声速飞行器转动部件动密封地面试验考核。Thermal structure, thermal match and thermal seal complementation ground test for rotatable parts such as airfoils and rudders is technically difficult in the research and development stage of strategic glide vehicles, and hypersonic vehicle flight test is a qualified solution to overcome this difficulty . Due to the difficulty in ground tests,the ctechniques were investigated in an arc heated wind tunnel. Technical solutions were proposed to solve key problems including the nitiation of the flow field,the flow field choking,and the flow field control in consideration of rotations. These techniques were successfully used for the rotatable parts in thermal structure,thermal match and thermal seal complementation surface heat flux distribution has good agreement with the one in the flight condition, and the flow field is stable when the rotatable part is rotating. It is the first rotating thermal sealcomplementation ground test in China.Keyword
