Application of the Saderholm erosive burning model to nozzleless solid propellant rocket motors

This paper demonstrates the ability of the Saderholm erosive burning model, when coupled with the Air Force Rocket Propulsion Laboratory Nozzleless Rocket Motor Internal Ballistics Computer Program, to predict the ballistic performance of six nozzleless rocket motors of three designs loaded with three nonaluminized HTPB propellants. The paper describes the Saderholm erosive burning model, the six nozzleless test motors, and the ballistics prediction methodology.
