Blue Flame was constructed in
Milwaukee, Wisconsin by
Reaction Dynamics, a company formed by Pete Farnsworth, Ray Dausman and Dick Keller, who had developed the first
hydrogen peroxide rocket dragster, called the X-1 and driven by Chuck Suba. The car used a combination of
high-test peroxide and
liquified natural gas (LNG), pressurized by helium gas. The effort was sponsored by the
American Gas Association, with technical assistance from the
Institute of Gas Technology of
Des Plaines, IL. The engine was designed by Reaction Dynamics and some of the components were manufactured by Galaxy Manufacturing of
Tonawanda, New York.
Blue Flames engine is a
regeneratively cooled variable-thrust liquid-propellant engine. It can operate on either a single- or dual-propellant basis. In operation, it permits natural gas use as a liquid, gas, or both with a two-stage combustion start. The oxidizer flow is established first, then LNG enters a heat exchanger where it vaporizes and is brought to combustion temperature. The gas is then injected into the combustion chamber with the oxygen provided by the hydrogen peroxide. A stable flame front is established and the remaining
liquified natural gas (LNG) is injected to bring the engine to full power. Nominal engine running time was 20 seconds at full thrust of , the equivalent of . Keller stated the
Goodyear Tire Company restricted their top speed to . Reaction Dynamics subsequently modified the LNG flow in the two-stage injector system to almost halve the maximum thrust. The actual thrust during the record runs was between [equivalent of ] and .
Blue Flames record runs involved accelerating continuously to the mile midpoint, then coasting through the mile. The peak speed, approximately , was reached at that point and then the vehicle decelerated the rest of the way. The kilometer speed trap was biased towards one end of the mile, resulting in the higher speed.
Blue Flame uses an aluminum semi-
monocoque with welded tubular structure in the nose section and an aluminum "skin." The vehicle is long, high to the top of the tail fin, and wide, with a
wheelbase of . It has an empty weight of and is approximately fully fueled and loaded. Goodyear designed 8:00-25 tires for the vehicle, with an outside diameter of and smooth tread surface to help prevent heat buildup, filled with
nitrogen gas at . == Land speed record ==
