Abstract
This paper presents the study,by means of comparison and alalysis,on the correlation of the measured data of the aerodynamic forces on an AGARD calibration model B in BIA′s hypersonic wind tunnel FD 07 with those in other hypersonic wind tunnels.To do the study of this kind is not only to comprehensively appraise the flow field characteristics and measurement level of wind tunnel FD 07,but also to offer necessary technological support for calibrating the procedure of numerical method.The research results show that,at Ma =4.94~7.96,the changing trends of the measured data of forces,moments and position of pressure center on the calibration model B in wind tunnel FD 07 with Mach numbers and angle of attack are in agreement with those in other hypersonic wind tunnels,meanwhile the variances of the measured data are also close to the fitting curves acquired in other hypersonic wind tunnels.
