【Abstract】 This paper introduces some results of theoretical and experimental aerodynamic investigation of base bleed by solid fuel combustion.It presents the influences of ejection parameter, freestream Mach number, boattail angle and length of model, geometric size of jet hole, as well as model rotary speed on drag reduction rate. It also suggests an analytical computational method for projectile base pressure under the condition of base bleed by solid fuel.更多还原
