Determination of detonation pressure and velocity for RDX/GAP propellant

Detonation velocity and detonation pressure have been determined for the solid propellant D- 07, a RDX/GAP propellant produced by Nammo Raufoss. Three firings, two with test item diameter 35.6+1 mm and one with diameter 29.1 mm, have been performed with only moderate variations in the results. For the detonation pressure an average pressure of 231+4 kbar was measured. The highest pressure, 236.4 kbar, was measured for the charge with the highest density. The measured detonation velocity for two of the test items was 7500 m/s. For the third test item, cast no. 11, with highest density, 1.679 g/cm3, the overall detonation velocity was measured to 8010 m/s.
