Novel polyurethane-based binders, specifically designed for environmentally responsible rocket propellant composites, were obtained by employing the polyester-polyols that resulted from the degradation of polyethylene terephthalate waste. A new class of “greener” rocket propellants, comprising polyurethanes (based on recycled PET) as the binder, ph...

The dependence of the specific impulse of metal-free energetic compositions based on high-enthalpy organic oxidizers on the elemental content and enthalpy of formation of the oxidizer and the nature and volume content of the composite binder consisting of hydrocarbon and active components has been studied. At a given volume content of the binder, t...

The energy capabilities of solid composite propellants in which the trinitromethyl groups of the oxidizer are replaced by fluorodinitromethyl groups are examined. This replacement is shown to lead to a significant decrease in the enthalpy of formation and, consequently, the specific impulse, but at the same time slightly reduces the sensitivity and...
Butacene® is a polymeric binder with ferrocenyl groups chemically bonded to HTPB backbone. Through incorporation in the AP−Al composite propellant formulation, it leads to high burning rates (BR) >20 mm/s at 7 MPa, and low pressure exponents n

The energetic potential of solid composite rocket propellants on the basis of solid and liquid nitro derivatives of azo- and azoxyfurazans was studied by using thermochemical calculations. Quantitative relationships were established between the energetic parameters of propellants, the selected binder, and the properties of the studied component. It...

Perchlorate anion (ClO4−) has been found in drinking water supplies throughout the southwestern United States. It is primarily associated with releases of ammonium perchlorate by defense contractors, military operations, and aerospace programs. Ammonium perchlorate is used as a solid oxidant in missile and rocket propulsion systems. Traces of perch...
Vier zweibasige Raketenfesttreibstoffe und ein einbasi Treibladungspulver wurden hinsichtlich Stabilisatorver Molmassenabbau und Wärmeentwicklung zwischen 50 Grad C C, bzw. 40 Grad C und 110 Grad C untersucht. Die Stabi wurde mit der Hochleistungsflüssigkeitschromatographie Molmassenabnahme mit der Gelpermeationschromatographie Wärmeentwicklung mit...
