The gas is then injected into the combustion chamber with the oxygen provided by the hydrogen peroxide. The oxidizer flow is established first, then LNG enters a heat exchanger where it vaporizes and is brought to combustion temperature. In operation, the engine permits natural gas use as a liquid or gas or both with a two-stage combustion start. It can operate on either a single or dual-propellant basis. The Blue Flame engine is a re-generatively cooled, liquid-propellent engine of the variable thrust type. was formed in 1966 by Donald J Magro and Gerald Muhs and was principally engaged in flow control systems, cavitating venturi, and precision machining fields. The engine of the Blue Flame was designed and manufactured by Galaxy Manufacturing Co. The effort was sponsored by The American Gas Association, with technical assistance from the Institute of Gas Technology of Des Plaines, IL. This was the original plan for the record runs in 1970. LNG was used in the actual record-setting performance but at a lower ratio of LNG to the hydrogen peroxide oxidizer than would be used at maximum design thrust. The Blue Flame used a combination of hydrogen peroxide and liquified natural gas (LNG), pressurized by helium gas to eclipse previous speed records set with jet engine powered vehicles. The Blue Flame was constructed in Milwaukee, Wisconsin by Reaction Dynamics, a company formed by Pete Farnsworth, Ray Dausman and Dick Keller who had developed hydrogen peroxide rocket dragsters. The driver, Gary Gabelich, was of Croatian ancestry and native of San Pedro, California. The Blue Flame was the high-performing, ultra high-speed, rocket-powered vehicle which achieved the world land speed record on Bonneville Salt Flats in Utah on October 28, 1970. First record set by a rocket powered car.
