On-Off and Acceleration Control of Solid Rockets

In order to improve the effectivity of rocket propulsion systems, thrust control has been employed. As a result, liquid bipropellant engines have been selected for operational propulsion systems for these advanced missiles. Controllable solid rocket motor technology programs conducted over the past 5-6 years have provided several promising controllable solid rocket motor concepts to accomplish these same complex missions previously assigned to liquid systems. This paper discusses many of these controllable solid rocket motor concepts, their advantages and disadvantages, and potential applications for this technology.
