Quick-Look Structural Analysis Techniques for Solid Rocket Propellant Grains

Abstract

Software was developed to provide the means to perform a 'quick-look' preliminary motor structural analysis within the AFRPL. Preliminary structural analysis equations from the JANNAF Structural Integrity Handbook and Galcit 101, 'Fundamental Studies Relating to Systems Analyses of Solid Propellants' were implemented on the HP 9815A programmable calculator as a basis for the software. For analysis of a motor undergoing a thermal transient load, software was written to provide the means to calculate an effective modulus, based on linear viscoelastic theory, for use in the 'quick-look' analysis. Supporting software was also written to provide graphical input of data and to correct any distortions appearing in supplied data. Finally, results from a simple, slow cooldown problem were obtained from a finite element analysis using the TEXGAP 2D computer code to verify the usefulness and accuracy of the 'quick-look' analysis and supporting software.
