ADAPTATION OF A TECHNIQUE FOR PREDICTING LARGE SOLID ROCKET MOTOR SPECIFIC IMPULSE FROM DATA OBTAINED IN MICROMOTORS.

Abstract

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)
