高超声速风洞模型自由翻滚动导数试验技术是为满足航空航天飞行器 0°～ 360°全攻角范围内的动导数测量及产生极限环振动现象的研究之急需而研制。简要介绍了试验技术研制的自由翻滚试验装置、液体轴承、角度测试系统与系统建模的大攻角非线性数据处理技术。该项技术已成功地为逃逸飞行器模型提供了满意的试验数据
Hypersonic wind tunnel model free rolling rolling derivative test technology is to meet the aerospace vehicle in the range of 0 ° ~ 360 ° angle of attack of the dynamic derivative measurement and the phenomenon of limit cycle vibration research is urgently needed. This paper briefly introduces the non-linear data processing technology of large-angle-of-attack, such as free roll test device, liquid bearing, angle test system and system modeling. The technology has successfully provided satisfactory experimental data for the Escape Aircraft model
