A new method for determining propelland strand burning rates without the use of timing wires has been developed. It was found that when the cross- sectional area of the strand is sharply varied at known intervals, the burning rate can be obtained from assessment of the resulting pressure-time trace. Results of the new method are within 1 of the standard wire technique. The method is applicable to difficult propellant systems and offers advantages of lower cost, higher reliability, and safety.
