Digital Computer Investigation of Ignition, Pressurizing and Performance of Solid Rocket Motors


Book Description

A digital computer analog model of a solid propellant rocket motor and performance evaluation system was developed. Heat and mass balance effects of the igniter, propellant, and insulation during ignition and chamber filling were modeled. Results include investigation of flame spreading, ignition criteria, and contribution by insulation to motor performance. Comparisons of predictions and experimental tests are included. An IBM model 7094 computer was used for the analysis. The FORTRAN computer program is included. (Author).










Development of a New Generation Solid Rocket Motor Ignition Computer Code


Book Description

This report presents the results of experimental and numerical investigations of the flow field in the head-end star grain slots of the Space Shuttle Solid Rocket Motor. This work provided the basis for the development of an improved solid rocket motor ignition transient code which is also described in this report. The correlation between the experimental and numerical results is excellent and provides a firm basis for the development of a fully three-dimensional solid rocket motor ignition transient computer code.
