The Research of Fluctuating Pressure and Buffeting Load on the Cone-column Body

Cao Xiaolong,Luo Jinling,Zhou Danjie,Wang Jing(Beijing electromechanical engineering institute,Beijing 100074,China)  
For the cone-column body,the character of fluctuating pressure during its subsonic flight,transonic flight and supersonic flight had been research in wind tunnel experiments.Regularity of the mean-square root and power density function with variational Mach number and attack angle had been analyzed.The distribution and influencing area of fluctuating pressure had been summarized.Regularity of fluctuating pressure had been proved with academic calculation and engineering experience.Synchronously,analysis of buffeting load had been deeply proved with fluctuating pressure characteristic.The buffeting load of the calculation model had been get,and it also been compared with immobile load.
