Abstract:

The importance of crack propagation in solid rocket motors is widely recognized. However, the processes of crack propagation and branching in burning solid propellants are not as yet well understood. These processes could be instrumental in creating large specific surface areas for burning causing rocket motor failure. Key factors influencing the crack combustion, propagation and branching process considered in the dimensional analysis include chamber pressurization rate, initial crack length, initial temperature, sample geometry, and mechanical and thermal properties of the solid propellant.
