Experiments Related to External Burning for Propulsion.

Abstract

An experimental study of base flows for a 2.25 inch diameter projectile at Mach 3 with cold air injection is reported. Upstream radial jet injection and base injection are used. The work is a continuation of a systematic study of many of the flow field features of external burning. It is shown that radial jet injection alters the wake structure, shortens the wake, and reduces the base pressure. In addition, the advantage of base injection using porous base bleed diminish with injection rate and external compression. (Author)
