Abstract : By employing uniaxial viscoelastic propellant data, it is demonstrated that normally neglected thermal gradients in propellant can significantly affect the results of a stress analysis in solid propellant rocket grains. The problems related to the direct measurement of stresses in solid propellant are identified and reviewed, and an appropriate stress transducer is proposed. (Author)
