Abstract

The burn area calc,ulhtion of al propellant, grain with taper convex star Port is discussed and a software developed, usIng a new zoning definition of the star cross-section,is elaborated. The evolution of lengthwise conditions,inclusion of a coupled sustainer mode, real-time calculations and
calculation for sliver burrling part make this software a versatile tool for propellant grain design and parametric studies.
