Incorporation of various flame coolants, particularly ferrous oxalate, cupric oxalate and submicron size Fe3O4 in N,N′-dihydroxyethane diamide containing gas generants results in cooler flame temperature and reduced HCN content. Use of downstream coolants further reduces evolved gas temperature and also further reduces HCN content. Devices incorporating these propellants are useful inflators for many devices such as helicopter flotation bags, cargo pallet soft-landing bags, aircraft escape slides, inflatable life rafts and similar items. They are particu...
A gas generator composition which produces less than about 0.7 mole percent of HCN upon combustion consisting essentially of a binder component, a polynitrate ester plasticizer component, N,N′-dihydroxyethane diamide and about 2% to about 8% by weight of a HCN scavenger component selected from the group consisting of cupric oxalate, ferrous oxalate, hydrates of ferrous oxalate, Fe3O4 and mixtures thereof.
