    Abstract: The reaction product is derived from a composition containing one of seven silanes; dimethyldiethoxysilane, methyldiethoxysilane, dimethyldimethoxysilane, diphenyldimethoxysilane, trimethylmethoxysilane, trimethylethoxysilane, or aminopropyltriethoxysilane, a multi-functional polydimethyl siloxane emulsified polymer, a compatible surfactant, ethanol and a majority component of water. In the method, the reaction product is applied to a heated surface of a mold core to create a semi-permanent coating to facilitate multiple releases of molded parts. If not heated, the mold core must be dried to remove water.

    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.

    Abstract: A solid propellant composition employing 2,2-bis(t-butyldicyclopentadienyon)propane (TBD) as the burn rate enhancer in a weight percent from about 2 to about 6 weight percent yields higher threshold values for ignition by impact and improved friction and spark testing values to thereby render the solid propellant composition less hazardous to personnel during handling as compared to similar solid propellant compositions containing Catocene, (2,2-bis(ethyldicylopentadienyliron)propane). The TBD solid propellant composition also comprises from about 9 to about 10 weight percent of hydroxyterminated polybutadiene binder system including an isocyanate curative added in amount of up to 1.0 weight percent and optional modifiers in small amounts with adjustment of the weight percent of other ingredients. Other propellant ingredients comprise a trimodal mix of 200, 1.7, and 0.7 micron particle sizes of ammonium perchlorate oxidizer in amounts from about 66 to about 70 weight percent, and aluminum metal powder in amounts from about 18 to about 20 weight percent. TBD is synthesized to contain no alpha hydrogens, i.e., does not have hydrogens on carbon adjacent to the aromatic ring structure which contributes to long term oxidation and migration problems of Hycat 6D and Catocene.
