An Analytical Investigation of the Caseless Rocket Motor

Abstract

An analysis of a caseless and nozzleless solid-propellant rocket motor employing the external burning concept was made. Performance was calculated for a wide range of supersonic flight conditions. The results of the analysis show that acceptable values of specific impulse and thrust are possible for propellants having sufficiently high burn rates in a base burning configuration. The effect of boattailing with combustion along the boattail was investigated and found to degrade the performance. An analysis of a thin planar airfoil with external burning occurring on part of its surface was also made. The specific lift, that is the ratio of the lifting force to propellant flow rate. was found to be an order of magnitude lower than the corresponding specific lift for a conventional airfoil propelled by a turbine engine.
