摘要: A model of a linear aerospike rocket nozzle that consists coupled aerodynamic and structural analyses has been developed. nonlinear computational fluid dynamics code is used to calculate the thrust, three-dimensional finite-element determine response weight. The will be demonstrate multidisciplinary design optimization (MDO) capabilities for relevant engine concepts, assess performance various MDO approaches, provide guide future application development. In this study, problem formulated using feasible (MDF) strategy. results MDF formulation are presented with comparisons against separate optimized designs. Significant improvements demonstrated by approach in comparison single-discipline
