This rocket motor propellant includes a combustible double-base propellant and non-carbonized, non-graphitized polymeric fibers dispersed in the double-base propellant. The double-base propellant is formed from a composition comprising nitrocellulose and at least one nitrate ester. Representative polymeric fibers include polyethylene, polypropylene, polyesters, polyamides, polyacrylonitriles and combinations thereof.

A gas generating eject motor includes a case containing an ignitable low temperature gas generant material that does not produce toxic gases upon the combustion thereof. The gas generant material is generally contained with a screen enclosure housed within the case. An igniter is disposed within the gas generant material for selectively igniting the gas generant to thereby generate combustion gases. A nozzle is disposed within an open aft end of the case for focusing and directing the combustion gases generated by the ignited gas generant material. The case is constructed and arranged to be separably attached to the aft end of a rocket to be launched from a launch platform, so that, upon ignition of the gas generant, the combustion gases focused by the nozzle will apply a thrust to the rocket and thereby propel, or eject, the rocket from the launch platform, at which time the combustible propellant of the rocket motor will ignite and the eject motor will be separated from the rocket.

An air bag igniter including a foamed material, and an air bag assembly containing the same are disclosed. The foamed material is formed from a composition including, as ingredients, a polyfunctional isocyanate, a polymeric binder having a plurality of hydroxyl groups which are reactive with the polyfunctional isocyanate, a fuel source, an oxidizer, and a foaming agent which may or may not be retained in the foamed material.
