Solid Rocket Motor Design Using Hybrid Optimization
International Journal of Aerospace Engineering, 2012 A particle swarm/pattern search hybrid optimizer was used to drive a solid rocket motor modeling code to an optimal solution. The solid motor code models tapered motor geometries using analytical burn back methods by slicing the grain into thin sections ...

A miniature solid propellant rocket motor [PDF]
33rd Joint Propulsion Conference and Exhibit, 1997 A miniature solid-propellant rocket motor has been developed to impart a specific motion to an object deployed in space. This rocket motor effectively eliminated the need for a cold-gas thruster system or mechanical spin-up system. A low-energy igniter, an XMC4397, employing a semiconductor bridge was used to ignite the rocket motor.
