초록

Solid propellant systems include a main propellant and a secondary propellant in contact with the first propellant that exhibits autoignition temperatures of at least about 100° F. lower than the autoignition temperature of the main propellant. The secondary propellant of the present invention is most advantageously employed with conventional AP-containing solid propellant formulations as the main propellant, especially formulations containing both AP, an energetic solid, and a binder. In especially preferred forms, the secondary propellant will include ...

1. A solid rocket motor propellant system comprising: (a) an ammonium perchlorate-based main propellant which comprises, based on the total weight of the main propellant, between about 65 to about 92 wt. % ammonium perchlorate (AP), between about 8 to about 25 wt. % of an inert binder, and optionally, between about 5 to about 20 wt. % of aluminum powder; and(b) a secondary propellant in the form of a strip in localized contact with said main propellant of a compressed mass of a composition which comprises, based on the total weight of the secondary prope...
