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.
