Book Description

A technique developed by the Rohm and Haas Company for specific impulse scaling has been adapted for use at the Air Force Rocket Propulsion Laboratory. The purpose of this technique is to predict specific impulse in large solid rocket motors based on data obtained in micromotors. As little as 2 pounds of propellant are required to obtain the data from which the prediction is made. The technique has been checked with a composite-modified-double-base propellant and a polybutadiene composite propellant. Within the limitations described, this technique can provide useful information concerning performance of a propellant in a large solid motor. Predictions, based on data obtained in micromotors, were within 0.6% of the delivered impulse in 6-pound motors and 70-pound BATES motors. (Author).

Book Description

This article introduces two predictive algorithms for the performance of solid propellant rocket motor. The emphasis is on the introduction of Time-Space Algorithm. The authors proposed a general two-dimensional grain calculation procedure in order to conduct the grain calculations. Therefore, the predictive algorithms for performance introduced by this article show generality. A comprehensive computer program for the aforementioned method has been written and applied to calculating the performance of three different solid rocket motors. The calculated results are consistent with those derived from experimental data.
