Experiments and Analysis Related to External Burning for Propulsion.
Abstract
An experimental study of base flow for a 2.25 inch diameter projectile at Mach 3 with and without simulated external burning disturbances is reported. Base pressure and wake structure results from systematic variations in axisymmetric external compression show that substantial base thrust can be produced and that the pressure and length scales of the external compression are imposed on the near wake. Measurements with comparable axisymmetric and asymmetric compression contours show that peripherial gradients reduce the base pressure rise. Furthermore, relatively large changes in the near wake length scales and a slight reduction in the base pressure occur when the solid-blockage effects of discrete radial fuel jets are modeled with pegs mounted near the base of the test projectile.
