  • Solid fuel gas generator for ducted rocket engine
    Patent number: 6258188
    Abstract: 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 (ZrH2) fuel element and carbon (C) as an optional fuel element.

  • Nitrate ester stabilizing layer for propellant grain
    Patent number: 5398612
    Abstract: Compositions and methods for increasing the storage life of a propellant grain by reducing the rate of decomposition of its nitrate ester components. A nitrate ester stabilizer is placed in a layer adjacent to a nonburning surface of the propellant grain. The stabilizer migrates from the layer into the grain's nonburning surface to provide additional stabilization for the entire grain, especially portions of the grain adjacent to the protected nonburning surface.
