THE MODIFIED WAGON WHEEL GRAIN DESIGN

Abstract

A modification of the wagon wheel grain design is considered in which short spears or spokes of propellant alternate with longer ones, and in which 3 different webs give rise to a 3-level surface-time history. There are 6 possible combinations of these webs under the limitation that the outer web must always be equal to or greater than either of the other 2. This report discusses the analysis for the case where W1 (major web) is greater than W2 (1/2 the thickness of the short spoke) is greater than W3 (1/2 the thickness of the long spoke), and presents tabulated data resulting from the solution for a wide range of parameters of the equations which characterize the design.
