Reverse design of solid propellant grain based on deep learning: Imaging internal ballistic data
The reverse design of solid rocket motor (SRM) propellant grain involves determining the grain geometry to closely match a predefined internal ballistic curve. While existing reverse design methods are feasible, they often face challenges such as lengthy

Reliability of solid rocket propellant grain under simultaneous action of multiple types of loads [PDF]
A case-bonded solid propellant rocket grain is subjected to many stress-inducing loads during the service life, due to temperature, extended polymerization, transportation, vibration, acceleration, aerodynamic heating etc.

Technique to Assess Aging of Propellant Grain
AbstractPhysical properties of composite propellants used in solid rocket motors change significantly with age. To predict the margin of safety and to reevaluate the remaining service life, the structural integrity analysis of solid propellant grains of aged rocket motors is pa-formed at various stages of their life span.
