Abstract: The reduced toxicity hypergolic bipropellant fuels of the present invention contain a hypergolic fuel and rocket grade hydrogen peroxide oxidizer, preferably HTP. The hypergolic fuel may be a reactive fuel or a catalytic fuel. The rocket grade hydrogen peroxide oxidizer consists of about 90 weight % to about 99 weight % H2O2, more preferably about 94 weight % to 99 weight % H2O2. However, hypergolic ignition may be attained with a H2O2 content as low as 70 weight % for some reactive fuels. The reactive fuel comprises about 6 weight % to 10 weight % reducing agent in a solvent. The catalytic fuel comprises about 6 weight % to 10 weight % catalytic agent in a solvent. The reactive fuels contain ingredients that are intrinsically reactive with rocket grade hydrogen peroxide. Upon contact with rocket grade hydrogen peroxide oxidizer, reactive fuels react vigorously with the hydrogen peroxide resulting in ignition. The catalytic fuels are produced by dissolving a catalytic agent in a solvent.
