28 April 1961: Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union, flew a prototype Mikoyan-Gurevich MiG-21F interceptor, the Ye-6T/1, 31 Red, to a Fédération Aéronautique Internationale (FAI) World Record for Altitude of 34,714 meters (113,891 feet).¹ This exceeded the record set five months earlier by Captain Joe B. Bailey, U.S. Air Force, with a Lockheed F-104C Starfighter, by 3,201 meters (10,502 feet). ²

The Ye-6T/1 and Ye-6T/3 were converted from the first and third MiG-21F prototypes. These experimental airplanes were built to test various missiles, engines and canard/wing configurations.

Ye-6T/1 was powered by a Tumansky R-11F2-300 afterburning turbojet engine and carried a liquid-fueled Sevruk S3-20M5A rocket engine mounted under the fuselage. The rocket produced 29.42 kilonewtons (6,614 pounds of thrust) at Sea Level. The prototype carried sufficient rocket fuel for 100 seconds burn time.

Mosolov set two world speed records with the Ye-6T/1 on 31 October 1959, with a performance of 2,388.00 kilometers per hour over a straight 15/25 kilometer course ³, and a 100 kilometer closed course.⁴

The Микоян и Гуревич МиГ-21-Ф-13 (Mikoyan-Gurevich MiG-21F-13) is a short-range supersonic interceptor with a “tailed-delta” configuration. The MiG-21-F-13 is 13.46 meters (44 feet,  1.9 inches) long, with a wingspan of 7.154 meters (23 feet, 5.7  inches), and height of 4.71 meters (15 feet, 5.4 inches). It has an empty weight of 4,871 kilograms (10,739 pounds), and a normal takeoff weight of 7,100 kilograms (15,653 pounds).

The MiG-21-F-13 was powered by a single Tumansky R-11F-300 engine. This is a dual-spool, axial-flow turbojet with afterburner,. It has a 6-stage compressor section (3 low- and 3 high-pressure stages) and a 2-stage turbine (1 high- and 1 low-pressure stage). The R-11F-300 is rated at 8,600 pounds of thrust (38.26 kilonewtons), and 11,200 pounds (49.82 kilonewtons) with afterburner.

The MiG-21-F-13 had a maximum speed of 1,200 kilometers per hour (746 miles per hour) at Sea Level, and 2,175 kilometers per hour (1,351 miles per hour) at high altitude. It could reach its service ceiling of 19,000 meters (62,334 feet) in just over 13 minutes. Its range is 1,300 kilometers (808 miles).

The -F-13 was armed with one Nudelman-Rikhter NR-30 30 mm autocannon with 30 rounds of ammunition, and two Vympel R-3S infrared-homing air-to-air missiles (NATO: AA-2A Atoll).

Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union

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 assigned as an instructor at the Chuguev Military Aviation School at 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, and Honored Test Pilot of the Soviet Union, 20 September 1967. The Fédération Aéronautique Internationale awarded him its Henry De La Vaulx Medal three times: 1960, 1961 and 1962. The medal is presented to the holder of a recognized absolute world aviation record, set the previous year.

On 11 September 1962, an experimental Mikoyan Ye-8 that Colonel Mosolov was flying suffered a catastrophic compressor failure at Mach 2.15. Engine fragments heavily damaged to prototype and it began to break apart. Severely injured, Mosolov ejected from the doomed airplane at Mach 1.78. He had suffered a severe head injury, two broken arms and a broken leg during the ejection and became entangled in the parachute’s shroud lines. His other leg was broken when he landed in a forest. The following day he suffered cardiac arrest. During a surgical procedure, he went in to cardiac arrest a second time.

Mosolov 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.

Georgy Mosolov served as an international representative for Aeroflot until 1992. He was also a department head at the Higher Komsomol School (Moscow University for the Humanities).

Mosolov was Chairman of the USSR Hockey Federation from 1969 to 1973. He was an Honored Master of Sports of the USSR.

Colonel Georgy Konstantinovich Mosolov, Soviet Air Forces, Hero of the Soviet Union, died 17 March 2018, at Moscow, Russia, at the age of 91 years. He was buried at the Vagankovsoye cemetery in Moscow.

4–9 February 1982: Sikorsky test pilots Nicholas D. Lappos,  Byron Graham, Jr., David R. Wright, and Thomas F. Doyle, Jr., set a series of Fédération Aéronautique Internationale (FAI) speed, time-to-climb and sustained altitude world records while flying a Sikorsky S-76A helicopter, serial number 760178, FAA registration N5445J, at Palm Beach, Florida.

On 4 February, Nick Lappos, who had made the first flight with the prototype S-76, set a record of 208.470 miles per hour (335.50 kilometers per hour) over a 3-kilometer course, and 212.888 miles per hour (342.61 kilometers per hour) over a straight 15/25 kilometer course.

On 5 February, Byron Graham, Jr., flew the S-76A to 3,000 meters (9,842.52 feet) in 3 minutes, 11 seconds; to 6,000 meters (19,685.04 feet) in 8 minutes, 37.3 seconds; and a sustained altitude of 7,940 meters (26,049.87 feet) in level flight.

On 6 February David R. Wright averaged 205.881 miles per hour (331.22 kilometers per hour) over a 100 kilometer closed circuit without payload (Class E1d), and 207.967 miles per hour (334.69 kilometers per hour) over a closed circuit of 100 kilometers without payload (Class E1e).

After taking a day off, the Sikorsky S-76A was back in the air on 8 February, this time with Thomas F. Doyle, Jr., flying the helicopter over the 500 kilometer closed circuit without payload. The Sikorsky averaged 214.833 miles per hour (345.74 kilometers per hour).

On the last day of the series, 9 February 1982, David R. Wright was back in the cockpit of N5445J. Flying the 1,000 kilometer closed circuit without payload, the S-76A averaged 189.580 miles per hour (305.10 kilometers per hour).

After 34 years, these six Fédération Aéronautique Internationale world records still stand.

N5445J was owned by Rodgers Helicopter Service, Kearney, Nebraska, until its U.S. registration was cancelled, 10 July 2006.

The record-setting helicopter eventually found its way to Rio de Janeiro, Brazil. Owned and operated by Atlas Taxi Aereo, 760178 had been re-registered as PR-IME and was transporting Petrobras employees to offshore oil production platforms. At approximately 8:30 a.m., 29 December 2008, PR-IME had departed Macaé Airport enroute Platform P-12 in the Campos Basin with 7 persons on board. Shortly after takeoff, the flight crew observed an AC generator caution light and returned to the airport. Before landing, a fire warning light also illuminated. Upon landing on Runway 24, all seven escaped from the burning helicopter without injury. The fire was quickly extinguished, but the Sikorsky S-76A was substantially damaged.

The Sikorsky S-76A is a twin-engine intermediate class helicopter that can be configured to carry 6 to 12 passengers. It is used as an executive transport, a scheduled passenger airliner, utility transport, and search and rescue aircraft. The helicopter is certified for instrument flight and has retractable tricycle landing gear.

The prototype was rolled out at Stratford, Connecticut on 11 January 1977 and the first flight took place on 13 March. It was certified in 1978 and the first production aircraft was delivered to Air Logistics, 27 February 1979.

The number 2 Sikorsky S-76 makes the type’s first flight, 13 March 1977. (Sikorsky Historical Archives)

The S-76A is 52 feet, 6 inches (16.00 meters) long with rotors turning. The fuselage has a length of 43 feet, 4.43 inches (13.219 meters) and a width of 8 feet (2.44 meters).  The helicopter’s overall height is 14 feet, 5.8 inches (4.414 meters). The four bladed composite main rotor is 44 feet (13.41 meters) in diameter. The blades are attached to a one-piece forged aluminum hub and use elastomeric bearings. As is customary with American helicopters, the main rotor turns counter-clockwise as seen from above. (The advancing blade is on the right.) The four-bladed tail rotor has a diameter of 8 feet (2.438 meters) and turns clockwise as seen from the helicopter’s left. It is mounted in a pusher configuration on the left side of the tailboom. The tail rotor is constructed of composite airfoils mounted to graphite spars.

The S-76A was equipped with two Allison 250-C30 turboshaft engines rated at 557 shaft horsepower, each. Subsequent variants have been built with Turbomeca Arriel 1S and 2S engines, as well as Pratt and Whitney PT6B-3A and PW210S engines with up to 1,077 shaft horsepower, each.

The S-76 has an empty weight of 7,007 pounds (3,178 kilograms). The S-76A maximum gross weight was 10,500 pounds (4,763 kilograms). Beginning with the S-67B, this was increased to 11,700 pounds (5,307 kilograms).

The Sikorsky S-76 has a maximum cruise speed of 155 knots (287 kilometers per hour). It can hover in ground effect (HIGE) at 7,050 feet (2,149 meters) or out of ground effect (HOGE) at 3,300 feet (1,006 meters). The service ceiling is 13,800 feet (4,206 meters).

The helicopter was designed with offshore oil support as a major consideration. It was intended to carry 2 pilots and 12 passengers 400 nautical miles. Maximum range with no reserve is 411 nautical miles (762 kilometers).

Sikorsky built 307 S-76As. More than 1,000 of all variants have been built. The current production model is the S-76D.

Fairey Rotodyne XE521 (FAI)
Fairey Rotodyne XE521 (FAI)

5 January 1959: At White Waltham, Berkshire, England, test pilots Ron Gellatly and Johnny Morton set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers Without Payload, flying the prototype Fairey Rotodyne, XE521, to an average speed of 307.22 kilometers per hour (190.90 miles per hour)¹ over a course from White Waltham Aerodrome to Wickham, Radley Bottom, Kintbury and back to White Waltham. The prototype was not a helicopter, but a compound gyroplane. Its record is for Class E (Rotorcraft), Sub-Class E-2 (Rotodyne).

The Fairey Rotodyne was a unique aircraft. Like a helicopter, it was capable of hovering and low-speed translating flight. The main rotor had both cyclic and collective pitch and provided roll and pitch control. Unlike a helicopter, though, thrust for forward flight was provided by two turboprop engines. Varying the propellers’ pitch provided yaw control for the aircraft until about 80 knots, when the twin rudders were sufficiently effective. As the Rotodyne accelerated in forward flight, the stub wing provided increasing lift and at about 60 knots, the main rotor tip jets were turned off. The main rotor continued to turn in autorotation, as in a gyrocopter.

Flight controls were similar to those of a helicopter, with a cyclic stick and collective lever with a twist throttle. The pedals, though, rather than controlling a tail rotor, varied the propeller blades’ pitch and rudder angle. The elevators were controlled by electric trim motors.

Helicopters’ maximum speed is limited by retreating blade stall. The Rotodyne’s stub wing provided 60% of lift in cruise flight, allowing the main rotor to operate with a lower blade angle of attack, delaying the onset of the stall. With propulsion provided by the turboprop engines rather than the main rotor, blade angle is further reduced. This allowed the Rotodyne to reach higher speeds in flight than a conventional helicopter.

Also, unlike a helicopter, the Rotodyne’s rotor was not driven by engines through a gear reduction transmission, reducing the aircraft’s weight and complexity. Drive was accomplished by tip-mounted high pressure jet engines (“tip jets”), fueled by compressed air supplied by the turboprop engines and turbine fuel. There is no torque effect, so an anti-torque rotor (tail rotor) is not required. The rotor mechanism is simplified because lead-lag hinges are not necessary.

XE521 made its first flight 6 November 1957 at White Waltham with Ron Gellatly and Johnny Morton in the cockpit.

The Rotodyne’s four-blade main rotor used symmetrical airfoils. It was 90 feet (27.432 meters) in diameter and the blade tip speed was 720 feet per second (219.5 meters per second). The blades had a chord of 2 feet, 3 inches (0.686 meters). The rotor blades were built of steel for strength, fatigue life and resistance to corrosion. The leading edge spar was machined from a 35 foot rolled steel billet and the rear spar was fabricated of layered stainless steel. The airfoil is shaped by pierced stainless steel ribs. The steel skin was a single sheet, joined at the trailing edge.

The wing span was 46 feet, 6 inches (14.173 meters). The engines and main landing gear were  carried in long nacelles mounted under the wing.

The Rotodyne’s fuselage was 58 feet, 8 inches (17.812 meters) long. The cabin has a length of 46 feet (14.021 meters) and is 8 feet (2.438 meters) wide and 6 feet (1.829 meters) high, providing space for 40 passengers or up to 9,000 pounds (4,082.3 kilograms of cargo. Clamshell doors at the aft end provided for cargo loading. Overall height of the aircraft was 22 feet, 2 inches (6.756 meters).

The Rotodyne was powered by two Napier & Son Eland NEl.3 turboprop engines with a maximum rated power of 2,805 shaft horsepower and 500 pounds of thrust at 12,500 r.p.m. for takeoff. Maximum continuous power was 2,180 shaft horsepower and 420 pounds of thrust. These engines drove four-bladed Rotol propellers with a diameter of 13 feet (3.962 meters). An auxilary compressor at the rear of the engine supplied compressed air for the main rotor tip-jets. Each engine supplied power to opposite pairs of of rotor blades at 250 °C. (482 °F.)

The prototype had an empty weight of 24,030 pounds (10,899.9 kilograms)

Squadron Leader Wilfred Ronald Gellatly, OBE AFC, RNZAF (Retired) was born in 1920. He joined the Royal New Zealand Air Force in 1940. During the last year of World War II, he commanded No. 243 Squadron, Royal Air Force. He attended the Empire Test Pilot School in 1950, and for the next four years was the helicopter flight commander at the Aeroplane and Armament Experimental Establishment at RAF Boscombe Down. In the New year’s Honors, 1 January 1954, the squadron leader was awarded the Air Force Cross. He joined Fairey Aviation as Chief Test Pilot. On 8 June 1963, Gellatly was awarded the Queen’s Commendation for Valuable Service in the Air.After the merger with Westland Helicopters at Yeaovil in 1967, remained with the company as chief test pilot. On 1 January 1970, Squadron Leader Gellatly was invested an Officer of the Most Excellent Order of the British Empire.  He retired from Westland in 1976 after having made the first flight of five new helicopters, including the Lynx. He died in 1983 at the age of 62 years.

Lieutenant Commander John George Peter Morton, OBE, Royal Navy Fleet Air Arm, was born in Lancashire, 10 May 1925. At Age 17 he entered the Fleet Air Arm and was sent to the United States for flight training. He was assigned to fly the Chance Vought Corsair from the aircraft carrier HMS Colossus. (One of the airplanes he flew, Corsair KD431, is on display at the Fleet Air Arm Museum, Yeovilton.)

Johnny Morton served as a test pilot on Supermarine Seafire XVs following the war, and then flew the Seafire from HMS Theseus, and then Sea Furies Sea Hawks from HMS Centaur.

The Royal Navy assigned Johnny Morton to Fairey Aviation as a test pilot. On 14 June 1969, Senior Test Pilot Morton was awarded the Queen’s Commendation for Valuable Service in the Air.

Morton was the lead test pilot on the Westland Wasp and the naval variant of the Westland Lynx. He made the first flight of Lynx XX469, 25 May 1972. On 21 November, XX469 suffered a tail rotor an dwas damaged beyond repair. Johnny Morton and his copilot were slightly injured. He was also the first pilot to roll the Lynx.

On 1st January 1975, John Peter George Morton was appointed an Officer of the Most Excellent Order of the British Empire.

After retiring from Westland, Morton and his wife moved to New Zealand. Lieutenant Commander John George Peter Morton OBE, died there, 4 May 2014, at the age of 88 years.

The leading edges of the wings and tail surfaces were swept to 45° and the fuselage of the F-105B incorporated the “area rule” which gave the Thunderchief its characteristic “wasp waist” shape. The Thunderchief was 63 feet, 1 inch (19.228 meters) long with a wingspan of 34 feet, 11 inches (10.643 meters). It was 19 feet, 8 inches high (5.994 meters). The F-105 had an empty weight of 27,500 pounds (12,474 kilograms) and a maximum weight of 46,998 pounds (21,318 kilograms).

Early production F-105Bs had the Pratt & Whitney J75-P-5 axial-flow turbojet engine. Beginning with the Block 20 aircraft, the more powerful J75-P-19 was installed. The -19 engine was retrofitted to the earlier aircraft. The J75-P-19 was a two-spool axial-flow turbojet engine with afterburner. It used a 15-stage compressor section (8 high- and 7 low-pressure stages) and a 2-stage turbine section. The J75-P-19 was rated at 16,200 pounds of thrust (72.06 kilonewtons), and 25,000 pounds (111.21 kilonewtons) with afterburner.

Armament consisted of one 20 mm General Electric M61 Vulcan six-barreled Gatling gun with 1,028 rounds of ammunition. The F-105 could carry up to 8,000 pounds (3,628.7 kilograms) of bombs in an internal bomb bay, or a total of 14,000 pounds (6,350.3 kilograms) of bombs, rockets or guided missiles on centerline or underwing pylons.

The F-105B had a maximum speed of 1,375 miles per hour (2,213 kilometers per hour). The service ceiling was 48,100 feet (14,661 meters). Maximum range was 2,200 miles (3,541 kilometers).

Republic Aircraft Corporation built 833 Thunderchiefs for the U.S. Air Force. 75 of those were F-105Bs. 372 F-105s were lost to enemy action in South East Asia.

Republic F-105B-20-RE Thunderchief 57-5812 served with the 119th Tactical Fighter Squadron, New Jersey Air National Guard and was later assigned to the 466th Tactical Fighter Squadron, 508th Tactical Fighter Wing at Hill Air Force Base, Utah. One source indicates that the the record-setting F-105B was used as a battle damage repair trainer at McClellan Air Force Base, Sacramento, California, from October 1980.

¹ Many sources cite General Moore’s World Record Speed for the 100-kilometer closed course at 1,216.48 miles per hour (1,957.745 kilometers per hour). The FAI’s official web site gives General Moore’s speed as 1,878.67 kilometers per hour (1,167.35 miles per hour). (See above.) Also, many sources (including General Moore’s official Air Force biography) state that General Moore won the Bendix Trophy for this flight. The Bendix Trophy was awarded to the winner of an annual West-to-East transcontinental air race. The Smithsonian Institution indicates that the Bendix Trophy was not awarded for the years 1958, 1959 or 1960.

25 September 1960: At Edwards Air Force Base, California, Commander John Franklin (“Jeff”) Davis, United States Navy, flew a McDonnell F4H-1 Phantom II to a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers Without Payload, averaging 2,237.37 kilometers per hour (1390.24 miles per hour).¹ Commander Davis flew the 62-mile circular course at an altitude of 45,000 feet (13,716 meters).

“On 25 September 1960 Davis flew the shorter, 100-kilometer course at 1,390.24 miles per hour, roughly Mach 2.2. He went around the course in a continuous circle, at 70° of bank and three g’s. The heavy bank put the honeycomb structure of the right stabilator directly in the engine exhaust the entire way around, but it held on. These two flights demonstrated the brute strength of the airframe and the sophistication of the F4H navigation system around the curves.”

John Franklin Davis was born at Chicago, Illinois, 4May 1921. He was the son of John E. Davis and Bernice B. McNair Davis.

On 11 July 1940, John Franklin Davis was admitted to the United States Naval Academy, Annapolis, Maryland, as a Midshipman. He graduated and was commissioned an Ensign, United States Navy, 9 June 1943. Ensign Davis served aboard the battleship USS New York (BB-34). He was promoted to Lieutenant (junior grade), 1 September 1944. He was promoted to Lieutenant, 1 April 1946.

Also in 1946, Lieutenant Davis qualified as a Naval Aviator. He was assigned as a pilot VF-74 aboard USS Midway (CVB-41). During the early 1950s, Lieutenant Davis served as operations officer for VF-191 aboard USS Oriskany (CVA-34). The squadron was equipped with the swept-wing Grumman F9F-6 Cougar. He then commanded VF-191, flying the Chance Vought F8U Crusader. Commander Davis was then assigned to the Bureau of Weapons as project officer for the McDonnell F4H Phantom II.

Following that assignment, Commander Davis was selected as executive officer of the Midway-class aircraft carrier, USS Coral Sea (CVA-43).

United States Navy aircraft carriers are traditionally commanded by Naval Aviators, but they usually are required to have experience commanding a “deep-draft” ship. Early in his career, Captain Davis had served aboard the 27,000-ton USS New York. He was given command of the Haskell-class attack transport USS Talladega (APA-208) from 10 April 1965 through 1966. From 30 September 1968 to 15 November 1969, Captain Davis commanded the supercarrier USS Kitty Hawk (CV-63) during combat operations in Southeast Asia.

Captain Davis was married to the former Miss Bonnie Adair of Bay St. Louis, Mississippi. They had six children.

Captain John Franklin Davis, United States Navy (Retired), died at Marrero, Louisiana, 16 May 1993. His ashes were spread at sea from his last command, USS Kitty Hawk.
