was also conducted to compare the burning rate versus pressure of a propellant including the pasted ballistic modifier of the present invention and a propellant not including the pasted ballistic modifier of the present invention specifically the propellant b11326 including the pasted ballistic modifier included 50 8 bttn 18 0 degdn 23 6 nc 2 0 mna 2 2 lc 12 15 pasted 0 4 c 1 0 flake aluminum 2 0 n 3200 curative the propellant b 11323 that does not include the pasted ballistic modifier included 52 9 bttn 18 6 degdn 24 0 nc 2 0 mna and 2 5 n 3200 curative the above percentages are weight percentages of the total weight of the propellant composition the bum rate was determined at various pressures and plotted logarithmically as provided in fig3 as can be seen from this plot the propellant lacking the pasted ballistic modifier exhibits a pressure exponent greater than 1 0 while the propellant of the present invention exhibits a pressure exponent less than 0 7 from 1000 2500 psi by formulating the propellants as taught by the present invention it is possible to avoid some of the significant problems encountered with conventional burn rate modifiers in particular the present invention provides compositions and methods for modifying a burn rate while minimizing the use of lead copper or similar materials pasting the ballistic modifier in an inert polymer allows better dispersion of the ballistic modifier in the propellant therefore requiring reduced amounts of the ballistic modifier which minimizes the toxicity associated with the use of metals the invention may be embodied in other specific forms without departing from its spirit or essential characteristics the described embodiments are to be considered in all respects only as illustrative and not restrictive the.
