User's Manual for FLAP 3.

Abstract

This manual describes a three-dimensional finite element computer code developed for the purpose of predicting the combustion instability of solid propellant rocket motors. The analysis requires the use of three separate codes which are described here. FLESH3 is used to generate a finite element mesh. FLSH3P is used to combine the segments generated in FLESH3 into the continuum for analysis. FLAP3 is used to calculate acoustic frequencies and mode shapes, to calculate the potential flow field, and to evaluate the stability integrals.
