Abstract: Prediction of crack growth, in solid propellants is one of very important problems in solid rocket motors. Its solving relys on experimental investigation to a great extent.This paper mainly shows some propellant samples which were used in foreign test of crack growth of typical propellants as well as their experimental methods,conditons and results.

Key words: Solid propellant;Crack propagation;Propellant test
