Abstract:

A study of 2 families of grain geometries, the internal burning star and the internal burning wagon wheel, was made. These 2 designs were particularily useful because they give a wide range of suitable characteristics, while permitting the propellant itself to protect the chamber walls against heating. The characteristics of side-burning grains were analyzed inA CROSS-SECTION PERPENDICULAR TO THE GRAIN AXIS FOR EACH OF THE 2 DESIGNS, WHILE THE POSSIBILITY OF TAPERING THE GRAIN AND THE INFLUENCE OF THE GRAIN END SURFACES WERE ALSO CONSIDERED. The geometries under consideration were presented as dimensionless to permit the maximum information in the minimum number of charts covering almost completely the useful range of the design parameters.
