Internal Ballistics of Powder Driven Rockets
Abstract
An approximate theory of the internal ballistics of rockets driven by colloidal propellants is developed In this report. A number of approximate relationships are derived which may be of use in preliminary design work. Particular emphasis is placed on the case of a constant chamber pressure. Included in the report are sample design calculations for a 3-in. 15-lb shell. The calculations are summarized on graphs which show the weight of TNT that can be carried as a function of the propellant charge weight, chamber pressure and muzzle velocity. The results show that the largest weight of TNT can be carried when the operating pressure is between 25 and 50 atmos. This result is then shown to apply equally well to all shells geometrically similar to the one considered.
