Investigation of External Burning Assisted Projectile.
Abstract
External burning reduces the base drag of a supersonic projectile by increasing the base pressure. Drag reduction is of interest due to the increase in range, decreased time of flight and/or increased impact velocity. Theoretically, the Crocco-Lees analytical model for base flow is reviewed for axisymmetric flow without heat addition and for planar flow with heat addition. A free jet wind facility has been constructed for simulation of a projectile with heat addition. Heat addition is found to give base thrust and, therefore, provides a method for increasing the performance of a gun system. (Author)
