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.

Russell Lowell Maughan was born at Logan, Utah, 28 March 1893. He was the sixth of eight children of Peter Weston Maughan, an accountant, and Mary Lucinda Naef Maughan. He attended Utah Agricultural College in Logan and graduated with a bachelor of science degree in 1917.

Maughan was commissioned as a second lieutenant in the U.S. Army Signal Officers Reserve Corps, 28 May 1917. He was promoted to first lieutenant, 8 January 1918. This commission was vacated 10 September 1920 and he was appointed a first lieutenant, Air Service, United States Army, retroactive to 1 July 1920.

On 14 August 1919, Maughan married Miss Ila May Fisher at Logan, Utah. They would have three children, but divorced sometime after 1940. His son, Russell L. Maughan, Jr., would become an officer in the U.S. Air Force.

Following the War, Lieutenant Maughan became a test pilot at McCook Field, Ohio. In 1921, he was reassigned to the 91st Observation Squadron, based at the Presidio of San Francisco.

On 14 October 1922, he won the Pulitzer Trophy Race at Selfridge Field, near Mount Clemens, Michigan, before a crowd of 200,000 spectators. He set two World Speed Record during the race with his Curtiss R-6: 330.41 kilometers per hour (205.31 miles per hour) over a distance of 100 kilometers, and 331.46 kilometers per hour (205.96 miles per hour) over a distance of 200 kilometers). On 29 March 1923, he set another World Speed Record, 380.75 kilometers per hour (236.587 miles per hour), again flying a Curtiss R-6.

On 23 June 1924, Lieutenant Maughan flew a Curtiss PW-8 Hawk from Mitchel Field, Long Island, New York, to the Presidio of San Francisco on the west coast of California, in an elapsed time of 21 hours, 47 minutes including refueling stops enroute. This was the “Dawn-to-Dusk Flight.” For this transcontinental flight, Maughan was awarded the Distinguished Flying Cross.

On 1 October 1930, Maughan was promoted to captain. He served in the Philippine Islands from 1930 to 1935, acting as an advisor to the government until 1932. From 1932 to 1935, he served as the post operations officer. He and his family lived in Manila. They returned to the United States aboard SS Columbus, a Norddeutscher Lloyd passenger liner, arriving at New York City from Southampton, 18 August 1935.

On 16 June 1936, Captain Maughan was promoted to major (temporary). That rank was made permanent 12 June 1939. He was again promoted, this time to lieutenant colonel, 11 March 1940.

During World War II, Lieutenant Colonel Maughan commanded the 60th Transport Group, a Douglas C-47 unit, 1941–42, and then, promoted to the rank of colonel, he commanded the 51st Troop Carrier Wing , which included the 60th, as well as eight other transport groups, during Operation Torch, the Allied invasion of North Africa.

On 25 October 1946, Colonel Maughan married Lois Rae Roylance in Nevada. She was 21 years his junior. They lived in Portland, Oregon.

Maughan was discharged from the U.S. Air Force, 30 November 1947, at the U.S. Army Hospital at Valley Forge, Pennsylvania. He died at the U.S. Air Force Hospital, Lackland Air Force Base, San Antonio, Texas, 21 April 1958, at the age of 65 years.

Tupolev Tu-114 CCCP-76459, holder of nineteen FAI World Records for Speed. (Уголок неба)

24 March 1960: Over a 1,000-kilometer course at Sternberg Point Observatory,¹ a Tupolev Tu-114 Rossiya four-engine turboprop airliner, serial number 88402, registered CCCP-76459, set eight Fédération Aéronautique Internationale flight records, including a world speed record of 871.38 kilometers per hour (541.45 miles per hour), while carrying a load of 25,000 kilograms (55,115.6 pounds).²

Colonel Ivan Moiseevich Sukhomlin.

The flight crew for these records were Tupolev Design Bureau senior test pilot Colonel Ivan Moiseevich Sukhomlin, Pilot, and Colonel Boris Mikhailovich Timoshok, Co-Pilot, and four others.

On 1 April 1960, Colonel Sukhomline flew the Tu-114 to set another seven speed records over a 2,000 kilometers course, at 857.277 kilometers per hour (532.687 miles per hour), while carrying a 20,000 kilogram payload (44,092 pounds).³

On 9 April, Colonel Sukhomlin and co-pilot Konstantine Sapielkine flew the Tu-114 over a 5,000 kilometer closed circuit, again with a 25,000 kilogram payload, at an average speed of 877.21 kilometers per hour (545.07 miles per hour). Four more FAI records were set.⁴

These are the fastest speed records ever established for any propeller-driven airplane. The records were retired by the FAI due to changes in rules.

The record-setting Tu-114 was the second production airliner.

The Tupolev Tu-114 Rossiya was a four-engine, turboprop-powered airliner developed from the Tu-95 Bear nuclear-capable long-range heavy bomber. It had a flight crew of five, two pilots, a navigator and two flight engineers, and could be configured to carry from 120 to 220 passengers, or 30,000 kilograms of cargo.

The Tu-114 made its first flight 15 November 1957 under the command of Colonel Alexei Petrovich Yakimov,  and began regular service with Aeroflot 24 April 1961.

The Tu-114 is 54.10 meters (177 feet, 6 inches) long, with a wingspan of 51.10 meters (167 feet, 8 inches) and overall height of 15.50 meters (50 feet, 10 inches). The wings are swept aft to 35° at ¼-chord, and they have significant anhedral. Total wing area is 311.1 square meters (3,348.7 square feet).

The airliner’s empty weight is 93,500 kilograms (206,132 pounds) and maximum takeoff weight is 179,000 kilograms (394,628 pounds).

The Tu-114 was powered by four Kuznetsov NK-12MV turboprop engines, each driving two contra-rotating four-bladed propellers. The NK-12 was rated at 14,795 shaft horsepower (10.89 megawatts). The NK-12 is a single-shaft axial-flow turboprop engine with a 14-stage compressor section and 5-stage turbine. The engine is 19 feet, 8.2 inches (6.000 meters) long, 3 feet, 11.3 inches (1.151 meters) in diameter, and weighs 5,181 pounds (2,350 kilograms).

The Tu-114 had a cruise speed of 770 kilometers per hour (478 miles per hour) at 9,000 meters (29,528 feet) (0.70 Mach), and a maximum speed of 894 kilometers per hour (556 miles per hour) at 8,000 meters (26,247 feet) (0.80 Mach). The airliner has a practical range of 7,000 kilometers (4,350 miles) and maximum ferry range of 8,800 kilometers (5,468 miles). The service ceiling as 12,000 meters (39,370 feet).

18 October 1922: At Selfridge Field, near Mount Clemens, Michigan, Assistant Chief of the Air Service Brigadier General William Mitchell set a Fédération Aéronautique Internationale (FAI) World Absolute Speed Record flying a Curtiss R-6 biplane, Air Service serial number A.S. 68564, over a 1 kilometer course at a speed of 358.84 kilometers per hour (222.973 miles per hour).¹

This was the same airplane with which Lieutenant Russell L. Maughan had won the Pulitzer Trophy just three days earlier.

Sources vary as to the speed General Mitchell attained, e.g., 222.96 m.p.h., 222.97 m.p.h., 224.28 m.p.h., and 224.4 m.p.h. A contemporary news magazine listed the officially recognized speed as 224.58 miles per hour (361.43 kilometers per hour):

American World’s Speed Record Homologated

The speed record made by General Mitchell, of the American Air Service, on October 18 last year, when he attained a speed of 224.58 m.p.h., has now been homologated by the International Aeronautical Federation.

“Billy” Mitchell had been the senior American air officer in France during World War I. He was a determined advocate for the advancement of military air power and encouraged his officers to compete in air races and attempt to set aviation records to raise the Air Service’ public profile. He gained great notoriety when he bombed and sank several captured German warships to demonstrate the effectiveness of airplanes against ships.

His outspoken advocacy resulted in the famous Court Martial of Billy Mitchell, in which a military court consisting of twelve senior Army officers found Mitchell guilty of insubordination. He was reduced in rank and suspended for five years without pay. Major General Douglas MacArthur (later, General of the Army, a five-star rank) said that the order to serve on the court was “one of the most distasteful orders I ever received.” Mitchell resigned from the Army and continued to advocate for air power. He died in 1936.

After his death, President Franklin D. Roosevelt elevated Billy Mitchell to the rank of Major General on the retired officers list. The North American Aviation B-25 twin-engine medium bomber was named “Mitchell” in recognition of General Mitchell’s efforts to build up the military air capabilities of the United States.
