Reliability Evaluation of Solid Propellant Tensile Strength

Tensile strength is an important physics performance index of solid propellant, and the degradation of this index is a crucial failure mode that results in the failure of solid propellant. This paper presents the model parameter estimation basing on the storage test data, and lower reliability confidence limit by means of fiducial inference and second order normal approximation. Based on the above two method, we have done lots of simulation.
