Curtiss R-6 Racer. (U.S. Air Force)

The Curtiss R-6 Racers were single-engine, single seat, fully-braced single-bay biplanes with fixed landing gear, developed from the U.S. Navy Curtiss CR. The airplane and its D-12 Conqueror engine were both built by the Curtiss Aeroplane and Motor Co., Garden City, New York.

The fuselage was a stressed-skin monocoque, built with two layers of wood veneer covered by a layer of doped fabric. The wings were also built of wood, with plywood skins and fabric-covered ailerons. Surface radiators were used for engine cooling.

The Curtiss R-6 was 19 feet, 0 inches (5.791 meters) long with a wing span of 19 feet, 0 inches (5.791 meters). It had an empty weight of 2,121 pounds (962 kilograms).

The R-6 was powered by a water-cooled, normally-aspirated 1,145.111-cubic-inch-displacement (18.765 liter) Curtiss D-12 dual overhead cam (DOHC) 60° V-12 engine, which was developed by Arthur Nutt, based on the earlier Curtiss K-12 which had been designed by Charles B. Kirkham. The D-12 had four valves per cylinder and a compression ratio of 5.7:1. It was rated at 415 horsepower at 2,000 r.p.m., and 460 horsepower at 2,300 r.p.m. During testing, it produced a 475 horsepower at 2,320 r.p.m. using a 50/50 mixture of 95-octane gasoline and benzol. The D-12 was a right-hand tractor direct-drive engine. It turned a two-bladed, fixed-pitch, forged aluminum propeller designed by Sylvanus Albert Reed, Ph.D. The Curtiss D-12 was 56¾ inches (1.441 meters) long, 28¼ inches (0.718 meters) wide and 34¾ inches (0.882 meters) high. It weighed 678.25 pounds (307.65 kilograms).

The racer had a range of 281 miles (452 kilometers) and a ceiling of  22,000 feet (6,706 meters).

Two R-6 Racers were built for the U.S. Army at a cost of $71,000, plus $5,000 for spare parts.

A.S. 68564 disintegrated in flight at the Pulitzer Trophy Race, 4 October 1924, killing its pilot, Captain Burt E. Skeel.
