The Assessment of Liquid Propellant Injectors. Part 1. Atomisation: Its Measurements and Influence on Combustion Efficiency of Rocket Motors

Abstract

One of the advantages of the rocket motor over other propulsion units lies in its ability to achieve a high rate of conversion of chemical energy into kinetic energy in a relatively small volume. In order to maintain the high rate and density of combustion required, the propellant is injected into the combustion caliber in the form of a spray consisting of a large number of small droplets. This spray has a large surface area per unit volume. which facilitates the transfer of heat from the combustion gases to the liquid propellant. Thus the high rate of evaporation from the liquid to the gaseous phase, necessary to maintains combustion, is achieved.
