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 two. This report discusses the analysis for the cases where w1 > w2 = w3, w1 = w2 > w3 and w1 = w3 > w2, and presents tabulated data resulting from the solution for a wide range of parameters of the equations which characterize the designs.
