Abstract
Incorporation of various flame coolants, particularly ferrous oxalate, cupric oxalate and submicron size Fe.sub.3 O.sub.4 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 particularly suitable when these items must be man-rated.
