| Abstract: | 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. |
