AN IMPROVED METHOD FOR THE MEASUREMENT OF SOLID PROPELLANT STRAND-BURNING RATES IN CLOSED BOMBS

Abstract

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.
