Bombardier was a monopropellant rocket concept that was designed to use high-proof hydrogen peroxide in an aerospike engine. The hydrogen peroxide reacts with a catalyst material inside of a reactor chamber. This reaction generates an enormous amount of heat which then vaporizes the hydrogen peroxide instantly, creating a steam powered rocket.
Hydrogen peroxide (HTP) has the molecular compound H2O2. The reaction that takes place splits off an oxygen atom from this compound. We had planned to further develop our reactor technology to become the heart of a bipropellant aerospike rocket system. The oxygen that splits off in the reaction is used as the oxidizer for the bi-propellant rocket.
