Progress in Design Optimization of Solid Rocket Propellant Grains

This paper describes a model search technique and a simplified performance model design optimization method on the basis of analyses of related literatures. In this method the thrust-time curve is regarded as the optimized object for performing design optimization of the grain geometry so that the design analysis can be simplified. Furthermore, the method has made a compromise of speed and accuracy to reduce the design period greatly.
