Abstract:

An existing computer program was modified to provide capability of evaluating the effects of solid propellant grain design asymmetrics caused by mandrel misalignment, and chamber bow or ovality. The computer code performs the necessary calculations to describe the regression history of an arbitrary singly perforated grain design. Modifications to the computer code consisted of adding supplemental subroutines to generalize the calculation scheme and to provide a plot display of grain periphery as a function of burn distance. A major effort was expended to define the respective grain and chamber wall periphery during a motor tailoff sequence.
