ABSTRACT:
A solid propellant composition employing 2,2-bis(t-butyldicyclopentadienyon)propane (TBD) as the burn rate enhancer in a weight percent from about 2 to about 6 weight percent yields higher threshold values for ignition by impact and improved friction and spark testing values to thereby render the solid propellant composition less hazardous to personnel during handling as compared to similar solid propellant compositions containing Catocene, (2,2-bis(ethyldicylopentadienyliron)propane). The TBD solid propellant composition also comprises from about 9 to about 10 weight percent of hydroxyterminated polybutadiene binder system including an isocyanate curative added in amount of up to 1.0 weight percent and optional modifiers in small amounts with adjustment of the weight percent of other ingredients. Other propellant ingredients comprise a trimodal mix of 200, 1.7, and 0.7 micron particle sizes of ammonium perchlorate oxidizer in amounts from about 66 to about 70 weight percent, and aluminum metal powder in amounts from about 18 to about 20 weight percent. TBD is synthesized to contain no alpha hydrogens, i.e., does not have hydrogens on carbon adjacent to the aromatic ring structure which contributes to long term oxidation and migration problems of Hycat 6D and Catocene.
