Modern SRM Ignition Transient Modeling. Part 4: Development of the Structural/Ballistic Analysis System SBAS-II

Abstract : Development continues on a system of computer codes for modeling propellant grains during ignition and burning, including the possibility of flaw initiation and growth. This system is known as the Structural/Ballistic Analysis System, or SBAS. It comprises a collection of separate computer codes which each address a different aspect of motor operation, including structural deformation, propellant burn-back, internal ballistics, gas flow, fracture propagation, and crack combustion. At the heart of the SBAS is an executive module that interfaces with each of the individual analysis codes transfers data from one to another, maintains a central module database. and includes model generation and examination functions.
