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&#xb0; 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 a nitramine which is at least one selected from nitroguanidine (NQ), cyclotrimethylene trinitramine (RDX) and cyclotetramethylenetetranitramine (HMX), and a binder which is at least one selected from HTPB, HTPE or glycidyl azide polymer (GAP). Most preferably, the secondary propellant will include a combination of nitramines which includes NQ and one of RDX or HMX.

An underwater explosive device, comprising a first container containing an explosive suitable for underwater use, and a second container surrounding the first container and containing oxygen gas under a pressure sufficient to enhance the underwater explosive reaction of the explosive.

An apparatus and method for protecting an occupant of a building from flying debris from a frangible structure of the building, such as a window or the like, in the event of an explosion or other blast. A protective barrier is positioned adjacent the building structure and is constructed to be deployed by inflation of at least a portion thereof. The protective barrier is movable from a stored position adjacent the building structure to a deployed position in which it covers the building structure. A gas generating device is connected to the protective barrier and is operable to generate gas to inflate the protective barrier and move it to the deployed position in response to the sensing of an explosion or other blast by a sensing device located remote from the building.
