4 November 1927: At Venezia, Mario de Bernardi flew a Macchi M.52 seaplane to a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course of 479.29 kilometers per hour (297.82 miles per hour).¹
Aeronautica Macchi built three M.52 seaplanes for the Regia Aeronautica (the Italian Air Force) for use in the 1927 Schneider Trophy Races. The M.52 was designed by Mario Castoldi. Like the earlier M.39, it was a single-place, single-engine, low-wing monoplane float plane constructed of wood and metal.
The three racers were each powered by a 2,116.14-cubic-inch-displacement (34.677 liter) liquid-cooled Fiat Aviazone AS.3 dual overhead camshaft, four-valve 60° V-12 engine which produced 1,000 horsepower at 2,400 r.p.m. The design of the AS.3 was based on the Curtiss D-12, although it used individual cylinders and water jackets instead of the American engine’s monoblock castings.
4 November 1923: At Mitchel Field, Mineola, Long Island, New York, Lieutenant Alford J. Williams, Jr., United States Navy, flew a specially-constructed Curtiss R2C-1 Racer to a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course, averaging 429.03 kilometers per hour (266.59 miles per hour).¹
Two R2C-1 Racers was built for the U.S. Navy by the Curtiss Aeroplane and Motor Company of Hammondsport, New York, and were assigned serial numbers A6691 and A6692. They were single-place, single-engine biplanes with a wooden monocoque fuselage and fabric-covered wings. Curtiss had made every effort to reduce aerodynamic drag, including the use of surface radiators on the wings to cool the engine. The airplane was 19 feet, 3 inches (5.867 meters) long with a wingspan of 22 feet (6.706 meters). The biplane had an empty weight of 1,692 pounds (767 kilograms) and gross weight of 2,112.3 pounds (958.1 kilograms).
The R2C-1 Racers were powered by a revolutionary 1,209.610-cubic-inch-displacement (19.813 liter) water-cooled, normally-aspirated Curtiss D-12A dual overhead camshaft (DOHC) 60° V-12 engine with four valves per cylinder. The cylinders and water jackets were cast as a monoblock and a drop-forged crankshaft with seven main bearings was used. A Stromberg NA-75 carburetor supplied the air/fuel mixture. The engine turned a two-bladed forged aluminum propeller designed by Sylvanus A. Reed. This fixed-pitch propeller had very thin blades which allowed it to turn at high speed without adverse sonic effects. The D-12A drove this propeller without gear reduction (direct drive, hence the “D” in the engine’s designation). The D-12A was specifically modified as a racing engine and did not have a power rating for normal service, however, it nominally produced 507 horsepower, with a 520 horsepower maximum. It was capable of operating at 2,500 r.p.m. 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).
Lieutenant Alford J. Williams, Jr., born at Bronx, New York, 26 July 1891, the first of four children of Alford Joseph Williams, a stone cutter, and Emma Elizabeth Madden William. He entered Fordham University in 1909, graduating with an A.B. degree. In 1913 Williams entered the university’s School of Law. He played professional baseball for two seasons with the New York Giants. Williams was 5 feet, 10 inches (178 centimeters) tall, weighed 145 pounds (66 kilograms), and had light brown hair and blue eyes.
Williams enlisted as a private in the New York National Guard, 4 March 1913. He was assigned to Company E, 7th Infantry. When the United States entered World War I, Williams, by then working as a machinist, joined the United States Naval Reserve Force (U.S.N.R.F.) as a seaman, 2nd class, and was trained in aviation at the Naval Aviation Detachment, Massachussetts Institute of Technology; the Naval Air Station, Bayshore New York; and at Pensacola Florida. During training he was promoted to Chief Quartermaster, Aviation. Williams was commissioned an Ensign, December 9, 1918.
Ensign Williams served as a gunnery and primary flight instructor at Pensacola, Florida before being assigned as a test pilot at the Naval Air Station at Hampton Roads, Virginia. He was promoted to lieutenant (junior grade), 1 April 1919, and to lieutenant, 1 July 1920. He remained at NAS Hampton Roads until being detached to fly high speed airplanes for the Pulitzer Trophy races. As of 9 October 1922, Williams had a total of 1,042 flight hours.
Appointed the Navy’s chief test pilot, he was considered to be a protégé of Rear Admiral William A. Moffet. This placed him in the center of a rivalry between Moffett and Captain Ernest J. King (later, Fleet Admiral). While Moffett was in Europe, Captain King had Lieutenant Williams transferred to sea duty. Williams was angry and in an ill-considered action, resigned his commission.
In 1925 Williams married Miss Florence Wright Hawes of Georgia.
During the 1930s, Williams requested and received a commission as a captain in the U.S. Marine Corps, and was soon promoted to the rank of major. However, Major Williams publicly advocated a separate Air Force, and for this he was forced to resign from the military.
Williams wrote Aviation from an Airman’s Standpoint, which was published in 1934.
Williams later served as Aviation Sales Manager for the Gulf Refining Company, Pittsburgh, Pennsylvania. He commuted with a Grumman G-58A Gulfhawk (a civil version of the F8F Bearcat fighter).
Al Williams retired from Gulf in 1951, and passed away 15 June 1958. He was buried at Arlington National Cemetery.
31 October 1959: At Joukovski-Petrovskoe, U.S.S.R., Гео́ргий Константи́нович Мосоло́в (Georgy Konstantinovich Mosolov), chief test pilot for Mikoyan-Gurevich, flew a prototype of the MiG-21 interceptor identified as the E-66, to set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course. His speed averaged 2,388 kilometers per hour (1,483.8 miles per hour).¹
The МиГ-21 prototype identified by the symbol E-66 is known at the Mikoyan Design Bureau as the E-6\3. Its first flight took place in December 1958. It is powered by a Tumansky 11F-300 afterburning turbojet engine. (A Wikipedia article suggests that this airplane was rebuilt to different configurations several times, with designations changed accordingly.)
Mosolov’s FAI altitude record of 28 April 1961 was also flown in a MiG-21 prototype called E-66. (FAI Record File # 8661) Photographs and motion picture film of that airplane show it marked with red numerals “31” on the forward fuselage.
Colonel Mosolov was interviewed for an article in Air & Space Smithsonian Magazine. He told writer Tony Reichhardt that after completing the speed record course, he was 125 miles (201 kilometers) from base at 44,000 feet (13,411 meters). Low on fuel, he shut down the turbojet engine and began a long glide. He twice unsuccessfully attempted to restart the engine for the landing, but was forced to glide all the way to the runway. After landing, the fuel system was drained. Only 8 liters (2.1 gallons) remained.
Georgy Konstantinovich Mosolov was born 3 May 1926 at Ufa, Bashkortostan, Union of Soviet Socialist Republics. He was educated at the Central Aviation Club, where he graduated in 1943, and then went to the Special Air Forces School. In 1945 he completed the Primary Pilot School and was an instructor at the Chuguev Military Aviation School (Kharkiv, Ukraine). In 1953 Mosolov was sent to the Ministry of Industrial Aviation Test Pilot School at Ramenskoye Airport, southeast of Moscow, and 6 years later, to the Moscow Aviation Institute. He was a test pilot at the Mikoyan Experimental Design Bureau from 1953 to 1959, when he became the chief test pilot.
Georgy Mosolov set six world speed and altitude records. He was named a Hero of the Soviet Union, 5 October 1960.
On 11 September 1962, an aircraft that Colonel Mosolov was flying suffered a catastrophic compressor failure at Mach 2.15 and began to break apart. Severely injured, Mosolov ejected from the doomed airplane at Mach 1.78. He survived but his test flying career was over. His recovery took more than a year, and though he was able to fly again, he could not resume his duties as a test pilot.
29 October 1953: Lieutenant Colonel Frank Kendall (“Pete”) Everest, U.S. Air Force, flew a new prototype air superiority fighter, North American Aviation’s YF-100A Super Sabre, serial number 52-5754, over the 3 kilometer and 15 kilometer courses at the Salton Sea, California.
For four runs on the short course, Everest averaged 757.75 miles per hour. Although this was 4.80 miles per hour (7.725 kilometers per hour) faster than the record set three weeks earlier by Lieutenant Commander James B. Verdin, U.S. Navy, with a Douglas XA4D-1 Skyray,¹ it was not fast enough to set a new world record under FAI rules, which required that a new record exceed the previous record by 1%.
Next came four speed runs over the 15/25 kilometer course. All runs were made with the Super Sabre flying within 100 feet (30 meters) of the ground. The official Fédération Aéronautique Internationale (FAI) average speed was 1,215.298 kilometers per hour (755.151 miles per hour)—0.99 Mach.²
The course at the Salton Sea was used because its surface lies 235 feet (72 meters) below Sea Level. The denser air causes undesired supersonic effects to occur at higher speeds, allowing the pilot a greater margin of control during the speed record runs.
Pete Everest joined the United States Army Air Corps shortly before the United States entered World War II. He graduated from pilot training in 1942 and was assigned as a P-40 Warhawk pilot, flying combat missions in North Africa, Sicily and Italy. He was credited with shooting down two German airplanes and damaging a third. Everest was returned to the United States to serve as a flight instructor. He requested a return to combat and was then sent to the China-Burma-India theater of operations. He shot down four Japanese airplanes. He was himself shot down by ground fire in May 1945. He was captured by the Japanese and suffered torture and inhumane conditions before being freed at the end of the war.
After the war, Everest was assigned as a test pilot at Wright-Patterson Air Force Base, Ohio, before going west to the Air Force Flight Test Center at Edwards Air Force Base, California. At Edwards, he was involved in nearly every flight test program, flying the F-88, F-92, F-100, F-101, F-102, F-104 and F-105 fighters, the XB-51, YB-52, B-57 and B-66 bombers. He also flew the pure research aircraft, the “X planes”: the X-1, X-1B, X-2, X-3, X-4 and X-5. Pete Everest flew the X-1B to Mach 2.3, and he set a world speed record with the X-2 at Mach 2.9 (1,957 miles per hour, 3,149.5 kilometers per hour) which earned him the title, “The Fastest Man Alive.”
Frank Everest returned to operational assignments and commanded a fighter squadron, two combat crew training wings, and was assigned staff positions at the Pentagon. In 1965, Everest was promoted to the rank of brigadier general. He was commander of the Aerospace Rescue and Recovery Service. He retired from the Air Force in 1973 after 33 years of service. General Everest died in 2004.
The YF-100A prototype had flown faster than Mach 1 on its first flight, 25 May 1953, with North American test pilot George S. Welch. It was the first airplane capable of supersonic speed in level flight
The North American Aviation F-100 Super Sabre was designed as a supersonic day fighter. Initially intended as an improved F-86D and F-86E, it soon developed into an almost completely new airplane. The fuselage incorporated the “area rule,” a narrowing in the fuselage width at the wings to increase transonic performance, similar to the Convair F-102A. The Super Sabre had a 49° 2′ sweep to the leading edges of the wings and horizontal stabilizer. The ailerons were placed inboard on the wings and there were no flaps, resulting in a high stall speed in landing configuration. The horizontal stabilizer was moved to the bottom of the fuselage to keep it out of the turbulence created by the wings at high angles of attack. The F-100A had a distinctively shorter vertical fin than the YF-100A. The upper segment of the vertical fin was swept 49° 43′.
There were two service test prototypes, designated YF-100A, followed by the production F-100A series. The first ten production aircraft (all of the Block 1 variants) were used in the flight testing program.
The F-100A Super Sabre was 47 feet, 1¼ inches (14.357 meters) long with a wingspan of 36 feet, 6 inches (11.125 meters). With the shorter vertical fin, the initial F-100As had an overall height of 13 feet, 4 inches (4.064 meters), 11 inches (27.9 centimeters) less than the YF-100A.
The F-100A had an empty weight of 18,135 pounds (8,226 kilograms), and gross weight of 28,899 pounds (13,108 kilograms). Maximum takeoff weight was 35,600 pounds (16,148 kilograms). It had an internal fuel capacity of 755 gallons (2,858 liters) and could carry two 275 gallon (1,041 liter) external fuel tanks.
The early F-100As were powered by a Pratt & Whitney Turbo Wasp J57-P-7 afterburning turbojet engine. It was rated at 9,700 pounds of thrust (43.148 kilonewtons) for takeoff, and 14,800 pounds (65.834 kilonewtons) with afterburner. Later production aircraft used a J57-P-39 engine. The J57 was a two-spool axial flow turbojet which had a 16-stage compressor, and a 3-stage turbine. (Both had high- and low-pressure stages.) The engine was 15 feet, 3.5 inches (4.661 meters) long, 3 feet, 5.0 inches (1.041 meters) in diameter, and weighed 4,390 pounds (1,991 kilograms).
The Super Sabre was the first U.S. Air Force fighter capable of supersonic speed in level flight. It could reach 760 miles per hour (1,223 kilometers) at Sea Level. (Mach 1 is 761.1 miles per hour, 1,224.9 kilometers per hour, under standard atmospheric conditions.) Its maximum speed was 852 miles per hour (1,371 kilometers per hour) at 35,000 feet (10,668 meters). The service ceiling was 44,900 feet (13,686 meters). Maximum range with external fuel was 1,489 miles (2,396 kilometers).
The F-100 was armed with four M39 20 mm autocannons, capable of firing at a rate of 1,500 rounds per minute. The ammunition capacity of the F-100 was 200 rounds per gun.
North American Aviation built 199 F-100A Super Sabres at its Inglewood, California, plant before production shifted to the F-100C fighter bomber variant. Approximately 25% of all F-100As were lost in accidents.
28 October 1936: Flying a four-engine Tupolev TB-3 bomber near Tchelcovo, U.S.S.R., Юмашев Андрей Борисович (Andrey Borisovich Yumashev, A.B. Yumashev, A. Youmachev, André Youmacheff), with a crewman named Kalachnikov, set a Fédération Aéronautique Internationale (FAI) World Record for Altitude With a 5,000 Kilogram (11,023 pounds) Payload, reaching 8,980 meters (29,462 feet).¹
The transport variant of the Tupolev TB-3 is identified as the ANT-6.
For the 28 October flight, Yumashev’s airplane was powered by four air-cooled, supercharged, 30.104 liter (1,837 cubic inches) Shvetsov ASh-62 nine-cylinder radial engines, rated at 1,000 horsepower at 2,200 r.p.m., each. This engine was developed from the earlier Shvetsov M-25, which was a license-built version of the Wright Aeronautical Corporation R-1820 Cyclone.
The previous month, Andrey Yumashev had set three similar world records. At that time the TB-3 had been powered by four liquid-cooled, supercharged, 46.928 liter (2,863.7 cubic inches) displacement, Mikulin AM-34FRN 60° V-12 engines with gear reduction, rated at 1,200 horsepower at 2,000 r.p.m. Interestingly, this engine had a different piston stroke length for the left and right cylinder banks, resulting in different displacement for each bank. On 11 September, Yumashev had flown the TB-3 to an altitude of 8,116 meters (26,627 feet) with a 5,000 kilogram payload.² On 16 September, he reached 6,605 meters (21,670 feet) while carrying 10,000 kilograms (22,046.23 pounds).³ Finally, on 20 September the Andrey Yumashev and the TB-3, this time with crewman Cheverdinsky, reached 2,000 meters (6,562 feet) with a 12,000 kilogram (26,455.47 pounds) payload.⁴
The Tupolev TB-3 was a four-engine heavy bomber built of a steel framework with corrugated steel skin panels. It had fixed landing gear. Initially, each main gear supported two wheels in a bicycle configuration. This was later changed to a single wheel and tire. While most were powered by liquid-cooled V-12 engines, various combinations of propellers were used. Some airplanes used wooden two-bladed propellers, while some used four-bladed propellers on the inner two engines. Later bombers used four-bladed propellers on all engines, while some ANT-6 transports used metal three-bladed variable-pitch propellers.
The first prototype had flown in 1930 and the TB-3 was in service until 1939, by which time it was obsolete. There were still more than 500 when the Great Patriotic War began in 1941. In addition to service as a heavy bomber, it also flew cargo and was a paratroop transport.
Major General Andrey Borisovich Yumashev was born at St. Petersburg, Russian Empire, in March 1902. He entered the army in 1918, serving with artillery units. In 1924 he trained as a pilot, serving as a combat pilot until 1927 when he became a test pilot at the Research and Testing Institute of the Air Force. Over the next ten years he tested fighters, bombers, and transports, and was appointed Test Pilot First Class.
In addition to the four payload-to-altitude world records above, from 12–14 July 1937 he was copilot of a Tupolev ANT-25 which flew from Moscow to San Jacinto, California, across the North Pole.⁵
Yumashev flew the Ilyushin DB-3 long-range bomber during the Soviet Finnish War of 1940 (“The Winter War.”) During the Great Patriotic War, he commanded the 2nd Independent Fighter Aviation Squadron in defense of Moscow, then the 237th Fighter Regiment at the Kalinin Front. He served as deputy commander of the 3rd Air Force at the Kalinin Front and then the 1st Air Army on the Western Front. By the spring of 1943, he was in command of the 6th Fighter Air Corps at the Central front. By 1944, General Yumashev commanded the Eastern Front Air Defense and the Southern Front Air Defense. He participated in the attacks against Königsberg and Berlin at the end of World War II.
A. B. Yumashev retired from the Soviet military in 1946. He then went on to become an accomplished artist.
During his military service, General Yumashev was named Hero of the Soviet Union, twice was awarded the Order of Lenin, and five times the Order of the Red Banner. He was also awarded the Order of the Red Star.
Major General Andrey Borisovich Yumashev died at Moscow, Russia, U.S.S.R., 20 May 1988.
