H2O2/Hydyne
H2O2/Hydyne propellant. Hydrogen peroxide and Hydyne would have represented a storable propellant combination with higher density than the usual nitric acid or N2O4 and hydrazine. Hydyne was a propellant blend of 60% UDMH and 40% diethyltrianine (DETA). It was pushed rather vigorously by the Redstone arsenal in the late 1950's, but found little application.

Specific impulse: 322 s. Specific impulse sea level: 276 s.

Propellant Formulation: H2O2-95%/Hydyne. Optimum Oxidizer to Fuel Ratio: 4.68. Temperature of Combustion: 2,900 deg K. Density: 1.27 g/cc. Oxidizer Density: 1.440 g/cc. Oxidizer Freezing Point: -1 deg C. Oxidizer Boiling Point: 150 deg C. Fuel Density: 0.860 g/cc. Fuel Freezing Point: -84 deg C. Fuel Boiling Point: 64 deg C.
