【Abstract】 In order to study the influence of the Reynolds number on the characteristics of fluctuating pressure for rotated body,test is conducted for the measurement of fluctuating pressure on the missile surface. Fluctuating pressures of the 14 axial feature points along the rotated body were measured,and the fluctuating pressure coefficient and the sound pressure level of the axial feature points along the model surface. Finally,this paper summarized the influence of the change of Reynolds number on fluctuating pressure coefficient and the sound pressure level at different Ma.更多还原
