OPTIMIZATION OF GRAIN AND STRUCTURE DESIGN OF A SOLID ROCKET MOTOR
Краткое описание
This work discusses the development of representative subsystem physical models and methods for the optimization of a solid rocket motor. The effect of the grain configuration on the optimum design is examined in detail along with other subsystems (winded case, case and nozzle insulation, etc.), which are modelled and integrated with the trajectory calculations to achieve the specified mission. The insulation mass and volumetric loading are affected by the grain design and are modelled as a function of the web fraction, thrust profile, and length-to-diameter ratio. The parameters optimized (via a genetic algorithm) are motor pressure, expansion ratio, burn time, thrust profile, nozzle exit angle, and grain length-to-diameter ratio. The effects of the various parameters and their relative influence on the optimum design are discussed through a single-stage launch of a capsule to a height of 100 km.
