SOLID PROPELLANT ROCKET MOTOR INTERNAL BALLISTICS COMPUTER PROGRAM. VOLUME 1. PROGRAM MANUAL

Abstract

This report describes a FORTRAN IV digital computer program developed to calculate internal ballistic performance of solid propellant rocket motors with high burning rates, short burning durations, and high vehicle accelerations. Forked wagon wheel, conventional wagon wheel, standard star, slotted-cone, and circular port monolithic and segmented grain designs may be considered. Accurate description of an inert sliver in the cylindrical section is allowed for all but the forked wagon wheel grain design. The effects of anisotropic burning of the propellant may be considered. The storage of mass and momentum (capacitance effects) and vehicle acceleration are included in the internal gas dynamic equations. Ignition transients may be calculated. Tabular input of the motor grain description is available for special grain configurations that cannot be described by the program geometry constants. Motor performance parameters such as delivered and vacuum thrust and total impulse, fore-head and aft-head total pressure, nozzle discharge flow, fore-head and aft- head total pressure integrals, pitch and roll moments of inertia, center of gravity locations, burn surface area, and weight of propellant remaining are printed for each time Interval.
