초록

In the development of new minimum signature ducted rocket technology, the U.S. Army MICOM Propulsion Directorate has conducted studies for the development of fuel-rich gas generators for ducted rockets. The propellant formulation goals of this study include increasing burning rate, pressure exponent, and combustion efficiency without significantly decreasing fuel value. Formulations described in this application contain an energetic nitramine-prepolymer, a range of curing agents, and zirconium hydride (ZrH.sub.2) fuel element and carbon (C) as an optiona...

청구항

[ We claim:] [1.]1. A solid fuel gas generator for ducted rocket engine comprising a range in weight percent of the following ingredients:i. an energetic nitramine prepolymer binder in the amount from 60-85 weight percent of the gas generator composition;ii. a curing and crosslinking agent selected from the group of curing and crosslinking agents consisting of hexamethylene diisocyanate, a polyfunctional isocyanate which is the reaction product of hexamethylene and water, and isophorone diisocyanate 5-15 weight percent of the gas Generator composition;ii...
