title = "An optimization approach of SRM sphere slot grain design based on improved differential evolution algorithm",
abstract = "The sphere slot is a 3D configuration of solid rocket motor (SRM) grain. Accompanied with multi-design-variable and strong constraints, its optimization is always a complicated problem. In this article, a methodology has been presented for the optimization of sphere slot grain configuration. Parameterized CAD model method and unsteady lumped parameter internal ballistic model are adopted to evaluate the performance of sphere slot grain to establish the optimization objective and constraint functions. An improved differential evolution algorithm incorporated with Oracle penalty function method is developed and applied on the optimization to solve global optimum solution converging difficulty of multi-variable constrained problem. The approach is validated by a small sphere slot SRM. The results illustrate it is effective method and has robustness and efficient capacity to explore the design space for global optimum solution of sphere slot grain.",
