Injection Processes in Liquid Regenerative Propellant Guns.

Abstract

In a previous report, 1 I discussed the analysis of experimental measurements for a 30mm regenerative liquid propellant gun. Discharge coefficients for the injection into the combustion chamber and values for the Sauter mean diameter of droplets in the combustion chamber were derived. More recently, pressure measurements were also taken in the gun tube. This allows the derivation of discharge coefficients for the flow into the tube. A number of improvements have been made in the inverse analysis. Also, work has been done in developing a transient model to predict the discharge coefficients into the combustion chamber. Keywords: Mathematical modeling, Liquid monopropellant; Regenerative gun; Lumped Parameter model; Fuel injection; Discharge coefficient; Droplet burning.
