Structural Assessment of Solid Propellant Grains (l'Evaluation structurale des blocs de poudre a' propergol solide)

Abstract

Solid propellant rocket motors and gas generators are used in military and civil devices. Missiles, boosters, space propulsion, pyrotechnic actuators are examples. The structural capability of the grain over time and under varying temperature, humidity, and mechanical loads, is of prime concern for the reliability, safety and service life of the device. From 1994 to 1996 an AGARD working group has collected, reviewed and evaluated the methods used for structural analysis of solid propellant grains within the NATO nations and has issued an advisory report consisting of 8 chapters: 1. Overview of Solid Propellant Rocket Motor Design 2. Application of Structural Integrity Assessment 3. Structural Analysis 4. Material Characterisation 5. Failure Criteria 6. Margin of Safety Determination 7. Verification 8. Recommendations and Conclusions Standardisation and preferable approaches are recommended.
