An Experimental Investigation of the Effects of Swirling Air Flows on the Combustion Properties of a Solid Fuel Ramjet Motor.

Abstract

A series of reacting flow tests of a solid fuel ramjet were conducted with different air inlet swirl. Cold flow measurements of the air flow at the exit plane of the tube-in-hole injector were used to determine the Swirl Number for each configuration. Regression rates of the HTPB fuel at low air mass flux were found to increase with swirl vane angle (and Swirl Number) up to 30 degrees. (Thesis). Keywords: Solid fuel ramjet; Swirling airflows; Regression rate; Swirl number; Tube-in-hole injector.
