Abstract:

A determination was made of the effect of long term storage at elevated temperature on the ballistic and chemical stability of WC ball propellants and DuPont cool burning propellants. Ammunition loaded with these propellants and M52A3B1 primers was placed in both normal and high temperature storage. Samples were withdrawn at 8-wk intervals over a period of 66 wk for chemical analysis and ballistic testing under a variety of conditions. The results indicated that of the 5 propellants tested, the IMR exhibited the greatest stability both ballistically and chemically. The cooler burning DuPont CR7516 exhibited higher average pressure levels and longer action times than the other propellants under test, but its performance otherwise was comparable to that of the other propellants.
