Reno Race #1 "Conquest"

Conquest I, Grumman F8F Bearcat, World Record Holder August 16, 1969

Darryl Greenamyer, a Lockheed Skunk Works® test pilot then flying the 2,100 mph (3360 km/h) Lockheed A-12 vehicle, flew a propeller-driven F8F Bearcat in the inaugural air race at Reno in 1964, where he had finished first, but lost on a technicality. The airplanes that year were basically surplus military fighters with only tune-ups to get them into racing trim. For 1965 Darryl was looking for a performance boost. He had previously tested the Lockheed F-104 jet fighter and was familiar with the boil-off cooling system incorporated in those airplanes Environmental Control System (ECS). He also knew that such a system had been on the German World Record airplanes. He asked Ben Rich, Propulsion Manager at Lockheed’s Skunk Works®, for help in making a similar system to cool the Bearcat’s engine oil. Ben in turn went to Pete Law, a young thermodynamics engineer in Lockheed’s Skunk Works®, who had worked on the F-104 ECS prior to 1961, and asked if he would work with Darryl in this after-hours project. After designing the basic system (Figure 2) Pete needed suitable oil coolers, which he found in a surplus yard across the runway from the Skunk Works® facility in Burbank. He settled on two 10-inch diameter oil coolers that had been used on the Lockheed Constellation transport to cool the oil lubricating the engine driven cabin pressurization superchargers.

With the boil-off oil cooler and other modifications to the airframe, e.g., clipped wings, Darryl won his first Reno Championship in 1965, with five more Championships to come in this same P&W R-2800 powered airplane. On August 16, 1969 he set a new FAI Class C-1 Group I 3 km speed record with a speed of 776.70 km/h (482.624 mph), breaking the record set thirty years earlier by Fritz Wendel in the Messerschmitt Bf 209 V1.

The oil coolers were mounted inside a box approximately 12” x 24” x 14” high. This package was installed in the airframe fuselage, behind the fuel and ADI tanks beneath the pilot’s seat. The vent for vapor then extended through the side of the fuselage. The engine ADI system consumed about 2.5 gpm (9.5 liters/min) of water/alcohol when at race power, and a similar amount of fluid for the oil cooling boiler. A tank held 90 gallons (340 liters) of ADI fluid, so power level greatly determined how long the aircraft could remain in the air. A typical race heat is about eight minutes in length. Similar boil-off oil coolers have been used in a number of other racers over the years.

After more than a decade as a racer Greenamyer donated the airplane to the Smithsonian Institution, where it is now displayed in the Udvar-Hazy Center near Dulles International Airport, Virginia.
