摘　　要：介绍了 0 .6m× 0 .6m自适应壁试验段的总体结构布局、测控处系统 ,研制中解决的主要技术难点问题和达到的主要技术指标。该试验段流场校测和利用DLR -GO¨TTINGEN一步迭代控制算法调整柔壁外形 ,获得模型阻塞度分别为 1 %和 2 8%两个标模试验结果。结果表明 :0 .6m× 0 .6m自适应壁试验段研制是成功的 ,流场品质优异 ,已基本具备了在M≤0 9、- 4°≤a≤ 1 0°范围内 进行全模型纵向测力试验并获得近于无干扰数据的能力。The paper introduces the development study of 0.6m×0.6m adaptive wall wind tunnel test section. It includes the overall structure, measurement, control and processing system, the main technical problems. It also includes the test results of flow field calibration and standard models (ε= 1% and ε= 2.8% ) under the flexible wall shape calculated by DLR-G O ¨TTINGEN method. The results show that the development study is successful. The quality of flow field is excellent. It has the capability to do model test on the condition of M≤0 9 and -4°≤α≤10°
