摘　　要：基于CARDC 8m×6m风洞特大迎角机构,通过对速压、测控、实时迎角测量、试验流程等各系统的改进,开展了连续扫描试验技术的研究工作,实现了某型战斗机和运输机的连续扫描测力试验,试验精准度达到了常规步进试验方式的同等水平,而获取的试验信息量及试验效率大幅提升。By improving the dynamic pressure control system,measurement and control system,real-time angle measurement and test process in the 8m×6m wind tunnel of CARDC,the continuous scan test technique based on the high angle of attack equipment was actualized,which was applied to one fighter plane model and one transport aircraft model force measurement tests.The results showed that the precision and accuracy of continuous scan test are on the same level as the conventional step by step test,but the former obtains more test data and greatly improves the test efficiency.
