Abstract
Abstract Gas-generating mixtures for rescue and air bag systems, as well as rocket d tubular weapon drive systems comprise high nitrogen and low carbon fuels GZT, TAGN, NG or NTO catalysts for pollutant gas reduction/reaction acceleration of V 2 O 5 /McO 3 mixed oxides and/or oxide mixtures, the oxidizer Cu(NO 3 ) 2 *3Cu(OH) 2 , which permits a cold, rapid combustion and optionally the additional coolant Fe 2 O 3 , which has further oxidizer characteristics.
