Detemination of Range Increasing for Base Bleed Projectile

This paper raised the limitation of range increasing rate and limitation ofprobable range increasing rate of base bleed projectile,and calculating method.Rela-tionship between decreasing drag rate and increasing range rate has been discussed.Inthe stage of demonstration and design of projectile,design method of base bleed projec-tile has been raised by limit probable range increasing rate.The paper had also dis-cussed the problem of the optimum bleed rate,the determination of the base bleedpropellant.
