IN-SITU SOLID ROCKET MOTOR PROPELLANT GRAIN AGING USING PNUEMATICALLY ACTUATED BLADDER

摘要

A method for non-destructively determining the mechanical properties of solid rocket motor propellant particles is the step of applying a force to the surface of the solid rocket motor propellant particles, wherein a strain is formed on the surface of the solid rocket motor propellant particles in response to the application, Applying, and calculating a value of the mechanical properties of the solid rocket motor propellant particles based on the deformation. This process can be carried out to determine the lifetime of the propellant particles over time.
