| Abstract: | This article is about the investigation of wind tunnel test in reducing projectile base drag with base bleed cold air.It discusses the effects of Mach number and the geometric parameters of base bleed opening on base drag and base pressure as well as the changes of them and shear angle with bleed rate. The experimental results and some simple analyses are presented. |
