Abstract

See full text

A method for non-destructively determining a mechanical property of a solid rocket motor propellant grain may comprise applying a force to a surface of the solid rocket motor propellant grain, wherein a deformation is formed on the surface of the solid rocket motor propellant grain in response to the applying, and calculating a value of the mechanical property of the solid rocket motor propellant grain based on the deformation. The force may be applied by moving a liquid into the perforation. This process may be performed over time to determine a lifespan of the propellant grain.
