Iterative Curve Fit of a Power Law Equation to Solid Propellant Shift Factor Data.

Abstract

Software was developed for an HP-9815A programmable calculator which optimizes the constants of a single-valued algebraic or transcendental equation to fit a given set of experimental data. This technique was used to fit a power law equation to solid propellant shift factor vs temperature data. The results were compared to optimization methods suggested by the JANNAF Solid Propellant Structural Integrity Handbook and to the Power Law approximation reported in AFRPL-TR-81-66 for the same data.
