风洞试验中模型迎角的视频测量及精度研究
Videogrammetric measurement of attack angle and its precision investigation in wind tunnel tests
摘要
Abstract
The measurement of attack angle is a base for the precision and accuracy of test data (the attack angles at the stall and minimum resistance points, for example, are the crucial data for aircraft developing and remodeling). Therefore, the method of videogrammetric measurement for attack angle is presented, and its accuracy is investigated. Several engineering tests of attack angle measuring in 2m supersonic wind tunnel have demonstrated that the accuracy of this approach was ≤0. 01°(the swings no more than 0. 01°can be perceived distinctly) , on the other hand the aerodynamic shape, rigidity and intensity of the model cannot be influenced, therefore it is useful and effective.关键词
