Г. В. Алфёров
Herman Vitalievich Alferov (Ге́рман Вита́льевич Алфёров) was born at Moscow, U.S.S.R., 11 April 1934. He learned to fly at the Moscow Flying Club at the age of 16. He was a flight instructor at the Russian National Aeroclub Chkalov, the oldest flying club in Russia, from 1952 to 1954. He graduated from the DOSAAF flight/technical school at Saransk in 1954.
Alferov was a test pilot at OKB Mil Design Bureau from 1954 until 1982. He made the first flights of many Mil helicopters, including the Mi-1 KX light helicopter in 1957, the first Soviet production turboshaft-powered helicopter, the heavy-lift Mi-6 (he was co-pilot), the twin-turboshaft Mi-2, Mi-10K flying crane, and the Mi-24 “Hind” attack helicopter (co-pilot). He was the lead test pilot for the Mi-24 at the Arsenyev aviation plant at Aresenev, Primorski Krai, in the Russian Far East from 1970, and for the Mi-26 beginning in 1978.
Herman Vitalievich Alferov died at Moscow, Russia, 9 January 2012, at the age of 77 years. During his aviation career, he had been awarded the Order of the October Revolution, Order of the Red Banner of Labor (two awards), Order of the Red Star (two awards), Order of the Badge of Honor, and was named an Honored Test Pilot of the Soviet Union. He had participated in setting five FAI world records for helicopters.

On 2 February, Gurgen Rubenovich Karapetian and Y. Chapaev flew to 6,400 meters (20,997 feet) with a 10,000 kilogram (22,046.2 pound) payload.¹
The OKB Mil Design Bureau’s Mi-26 is the world’s largest helicopter. It is a twin-engine, single main rotor/tail rotor helicopter with fixed tricycle landing gear. It is normally operated by two pilots, a navigator, flight engineer and flight technician, and can carry as many as 90 passengers.
The Mi-26 has an overall length with rotors turning of 40.025 meters (131 feet, 3.8 inches) and height of 8.145 meters (26 feet, 8.7 inches). The main rotor has a diameter of 32.00 meters (104 feet, 11.8 inches). The helicopter has an empty weight of 28,200 kilograms (62,170 pounds) and maximum takeoff weight of 56,000 kilograms (123,459 pounds).
The eight-blade fully-articulated main rotor system turns clockwise at 132 r.p.m. (the advancing blade is on the left). A five-blade tail rotor is mounted on the right side of a pylon in a pusher configuration. The tail rotor turns clockwise as seen from the helicopter’s left side (the advancing blade is below the axis of rotation).
Power is supplied by two Lotarev D-136 turboshaft engines producing 8,500 kW (11,399 shaft horsepower), each.
The cruise speed of the Mi-26 is 255 kilometers per hour (158 miles per hour) and maximum speed is 295 kilometers per hour (183 miles per hour). The hover ceiling, out of ground effect (HOGE), is 1,800 meters (5,905 feet), and the service ceiling is 4,600 meters (15,092 feet), though on 2 February 1982, test pilot Gurgen Karapetyan, who flew with Grishchenko at Chernobyl, flew an Mi-26 to 6,400 meters (20,997 feet) carrying a 10,000 kilogram (22,046 pound) payload.¹ The maximum payload is 20,000 kilograms (44,092 pounds). The helicopter’s range, carrying an 18,000 kilogram (39,683 pounds) payload is 670 kilometers (416 miles).
The Mi-26 first flew in 1977. Production began in 1980. The helicopter remains in service with both military and civil operators.

Gurgen Rubenovich Karapetyan (Гурген Рубенович Карапетян) was born 9 December 1936 in what is now Ekaterinberg, Sverdlovsk, Russia. He learned to fly a Polikarkpov Po-2 (NATO identifier, “Mule”) at the Sverdlovsk flying club at the age of 15.
Karapetyan served in the Soviet Air Force from 1956 to 1963. His rank was first lieutenant. An uncle advised him to attend the Moscow Aviation Institute, and he graduated in 1961. He worked as an engineer at Mil Design Bureau and then attended test pilot school. From 1962 to 1993, Karapetyan was a test pilot for the Mil Moscow Helicopter Plant, becoming the chief test pilot in 1974.
Gurgen Rubenovich Karapetyan
In April 1986, along with Anatoly Demyanovich Grishchenko, Gurgen Karapetyan flew a Mil Mi-26 helicopter dropping loads of sand and wet cement on the wreckage of the Chernobyl Reactor Number 4, which had been destroyed by an explosion. Carrying 15 ton loads suspended from an 800-foot (244 meters) cable, they made repeated trips while flying through the radioactive gases released from the plant. Grishchenko later died as a result of radiation exposure.
On 24 January 1993, President Mikhail Gorbachev named Karapetyan a Hero of the Soviet Union. He was twice awarded the Order of Lenin, and is an Honored Test Pilot of the Soviet Union.
Gurgen Karapetyan has set 10 world records in helicopters. He has flown more than 5,500 hours in 39 helicopter types.
Gurgen Rubenovich Karapetyan died 6 December 2021 at the age of 84 years.

The flight profiles for the record attempts were developed by McDonnell Douglas Chief Developmental Test Pilot, Charles P. “Pete” Garrison (Lieutenant Colonel, U.S. Air Force, Retired).
Streak Eagle carried only enough fuel for each specific flight. It was secured to the hold-back device on the runway and the engines were run up to full afterburner. It was released from the hold-back and was airborne in just three seconds.
When the F-15 reached 428 knots (793.4 kilometers per hour), the pilot pulled up into an Immelmann turn, holding 2.5 Gs. Streak Eagle would arrive back over the air base in level flight at about 32,000 feet (9,754 meters), but upside down. Rolling right side up, Streak Eagle continued accelerating to Mach 1.5 while climbing through 36,000 feet (10,973 meters). It would then accelerate to Mach 2.2 and the pilot would pull the fighter up at 4.0 Gs until it reached a 60° climb angle. He held 60° until he had to shut down the engines to prevent them from overheating in the thin high-altitude atmosphere.
After reaching a peak altitude and slowing to just 55 knots (63 miles per hour, 102 kilometers per hour), the airplane was pushed over into a 55° dive. Once it was below 55,000 feet (16,764 meters) the engines would be restarted and Streak Eagle returned to land at Grand Forks.

Streak Eagle is a very early production F-15A-6-MC Eagle, a single-seat, twin-engine air superiority fighter. It is 63 feet, 9.0 inches (19.431 meters) long with a wingspan of 42 feet, 9.7 inches (13.048 meters) and overall height of 18 feet, 5.4 inches (5.624 meters). The F-15A has an empty weight of 25,870 pounds (11,734 kilograms) and its maximum takeoff weight (MTOW) is 44,497 pounds (20,184 kilograms).
The F-15A is powered by two Pratt & Whitney JTF22A-25A (F100-PW-100) afterburning turbofan engines. The F100 is a two-spool, axial-flow turbine engine with a 3-stage fan section; 10-stage compressor; single chamber combustion section; and 4-stage turbine (2 low- and 2 high-pressure stages). The engine has a Maximum Continuous Power rating of 12,410 pounds of thrust (55.202 kilonewtons); 14,690 pounds (65.344 kilonewtons, 30-minute limit; and a maximum 23,840 pounds (106.046 kilonewtons), 5-minute limit. The F100-PW-100 is 191 inches (4.851 meters) long, 46.5 inches (1.181 meters) in diameter, and weighs 3,035 pounds (1,376.7 kilograms).
The cruise speed of the F-15A Eagle is 502 knots (578 miles per hour/930 kilometers per hour). It has a maximum speed of 893 knots (1,028 miles per hour/1,654 kilometers per hour) at 10,000 feet (3,048 meters), and 1,434 knots (1,650 miles per hour/2,656 kilometers per hour) at 45,000 feet (13,716 meters). The ceiling is 63,050 feet (19,218 meters) at maximum power. It can climb at an initial 67,250 feet per minute (342 meters per second) from Sea Level, and with a thrust-to-weight ratio of 1.15:1, The F-15 can climb straight up. The Eagle’s combat radius is 638 nautical miles (734 statute miles/1,182kilometers).
The F-15A is armed with one General Electric M61A1 Vulcan 20mm rotary cannon with 938 rounds of ammunition, four AIM-7 Sparrow radar-guided missiles and four AIM-9 Sidewinder heat-seeking missiles.
384 F-15A Eagles were built before production shifted to the improved F-15C version. As F-15Cs became operation, the F-15As were transferred to Air National Guard units assigned to defend continental U.S. airspace. The last F-15A was retired from service in 2009.
McDonnell Douglas F-15A-6-MC Streak Eagle 72-0119. (U.S. Air Force)
Streak Eagle was specially modified for the record attempts. Various equipment that would not be needed for these flights was eliminated: The flap and speed brake actuators, the M61A1 Vulcan 20 mm cannon and its ammunition handling equipment, the radar and fire control systems, unneeded cockpit displays and radios, and one generator.
Other equipment was added: A long pitot boom was mounted at the nose with alpha and beta vanes, equipment for the pilot’s David Clark Company A/P-225-6 full pressure suit, extremely sensitive accelerometers and other instrumentation, extra batteries, an in-cockpit video camera aimed over the pilot’s shoulder, and perhaps most important, a special hold-down device was installed in place of the fighter’s standard arresting hook.
These changes resulted in an airplane that was approximately 1,800 pounds (817 kilograms) lighter than the standard production F-15A. This gave it a thrust-to-weight ratio of 1.4:1.
Because Streak Eagle was a very early production airplane its internal structure was weaker than the final production F-15A standard. It was considered too expensive to modify it to the new standard, so it was transferred to the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio, in December 1980.

The flight profiles for the record attempts were developed by McDonnell Douglas Chief Developmental Test Pilot, Charles P. “Pete” Garrison (Lieutenant Colonel, U.S. Air Force, Retired).
Streak Eagle carried only enough fuel for each specific flight, and for the 20,000 meter climb, weighed 29,877 pounds (13,552 kilograms). It was secured to the hold-back device on the runway and the engines were run up to full afterburner. It was released from the hold-back and was airborne in just three seconds.
When the F-15 reached 428 knots (793.4 kilometers per hour), the pilot pulled up into an Immelman, holding 2.5 Gs. Streak Eagle arrived back over the air base, in level flight at about 32,000 feet (9,754 meters), but upside down. Rolling up right, Streak Eagle continued accelerating to Mach 1.5 when the pilot pulled the fighter up at 4.0 Gs until it reached a 55° climb angle until it reached 20,000 meters
Because Streak Eagle was a very early production airplane, its internal structure was weaker than the final production F-15A standard. It was considered too expensive to modify it to the new standard. It was transferred to the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio, in December 1980.
