Hydrogen Peroxide Propulsion Guide

guide hydrogen peroxide Propulsion

X-15 hydrogen peroxideHydrogen peroxide (H2O2) (in a 60 percent by weight aqueous solution) was first utilized as an energy source for underwater propulsion in Germany in 1934; this work led to its subsequent application (in higher concentrations) during World War II for auxiliary propulsion and gas generation concepts in aircraft and rockets. Its use in these areas resulted from its thermally or catalytically initiated exothermic decomposition (with substantial heat release) to yield a gaseous mixture of oxygen and superheated steam. Although its advantages as a mono-propellant include a 47 w/o available oxygen content, high density, high boiling point, unlimited availability and nontoxic exhaust gases, the initial areas of application for hydrogen peroxide were limited because of its questionable storage stability.

The use of H2O2 has been expanded with improvements in its stability, through stabilization additives and increased purification. Currently, H2O2 is the primary monopropellant used for underwater propulsion, aerospace propulsion, and auxiliary power concepts. H2O2/water solutions can now be stored for extended periods without significant degradation (decomposition rates of greater than 0.1 percent/year are readily available). Reaction control systems using hydrogen peroxide have already demonstrated space storability in excess of 2 years (with an estimated storability of 5 years). The use of H2O2 as a monopropellant in the aerospace industry has been widespread in the areas of station maintenance, space maneuvering, thrust vector control, power generation. Some examples of systems which have used hydrogen peroxide include the V-2 (gas generator), Redstone (gas generator), Mercury Spacecraft (reaction control system) and Astronaut Maneuvering Unit (main propulsion). Although the use of H2O2 in operational bipropellant systems has been limited thus far to extremely high performance aircraft rockets, hydrogen peroxide is potentially applicable to a variety of liquid bipropellant and hybrid propellant systems. Propellant-grade hydrogen peroxide is dofiaea in this report as high-purity oxygogen peroxide/water solution in which the hydrogen peroxide conentration is greater than 70 percent by weight.
