The E-152\1 (also known as Ye-152-1) was a prototype interceptor, similar to the production MiG-21. In documents submitted to FAI, the E-152\1 was identified as E-166. Colonel Mosolov made the first flight of the E-152\1 on 21 April 1961. The aircraft displayed at The Central Museum of the Air Forces at Monino, Russia, as E-166 is actually the E-152\2, sister ship of Colonel Mosolov’s record-setting prototype.

This airplane set two other FAI world records. Test Pilot Alexander Vasilievich Fedotov flew it to 2,401 kilometers per hour (1,492 miles per hour) over a 100 kilometer course, 10 October 1961; ² and on 11 September 1962, Pyotr Maksimovich Ostapenko set a world record for altitude in horizontal flight of 22,670 meters (74,377 feet feet).³

The Mikoyan Gurevich E-152\1 is a single-place, single-engine delta-winged prototype all-weather interceptor. It is 19.656 meters (64.448 feet) long  with a wingspan of 8.793 meters (28.848 feet). The leading edge of the wings are swept back to 53° 47′. The empty weight is 10,900 kilograms (24,030 pounds) and takeoff weight is 14,350 kilograms (31,636 pounds).

It was powered by a Tumansky R-15B-300 turbojet engine producing 22,500 pounds of thrust (100.085 kilonewtons) with afterburner. This was the original engine for the MiG-25.

Maximum speed Mach 2.82 (3,030 kilometers per hour, 1,883 miles per hour) at 15,400 meters (50,525 feet). The service ceiling is 22,680 meters (74,405 feet). Internal fuel capacity is 4,960 liters (1,310 gallons), and the E-152\1 could carry a 1,500 liter (396 gallon) external fuel tank. Its range is 1,470 kilometers (913 miles).

After a two-year test program, E-152\1 and its sistership, E-152\2 were converted to E-152M\1 and E-152M\2.

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.

3 June 1953: Concluding a series of speed and altitude records, Jackie Cochran set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15-to-25 Kilometer Straight Course with an average speed of 1,067.68 kilometers per hour (663.43 miles per hour) while flying the Canadair CL-13 Sabre Mk.3 No. 19200 at Edwards Air Force Base, California.¹

In the previous weeks, Jackie Cochran had flown the experimental Orenda-powered Sabre to world records over the 100 and 500 kilometer closed circuit and set an altitude record of 14,377 meters (47,169 feet).² During these flights, she became the first woman to “break the sound barrier” when the Sabre Mk. 3 exceeded Mach 1.

On the morning of 3 June, Cochran had attempted to set a new world record over the 3 kilometer straight course, which was flown at an altitude of 200 feet (61 meters). After two runs she determined that the Sabre Mk.3 would not exceed the previous record, and she abandoned the attempt.

In her autobiography, she wrote:

The plane was immediately refueled and the timing devices were shifted to the 15-kilometer course. That took about two hours and the roughness in the air was building up by the minute. A pass in each direction over the 15-kilometer course was needed for an average speed, as against four passes over the 3-kilometer course. I had fuel enough for four passes. The average of any two consecutive passes could be taken. The first pass from south to north was at a speed of 680 miles per hour. That result was relayed to me by air from my own Lodestar, which was parked on the lake bed near the judges’ equipment. The second pass from north to south, with the wind against me, was at a speed of 670 miles per hour. I determined to make a third pass, even though the plane had developed a bad left-wing down roll at high speed and was in consequence next to unmanageable over the level flight course and its approaches. On this third pass I decided to take a long dive at the conclusion of which I would level out before reaching the approach to the course. I did this but, on leveling out, the controls again “froze” on me with the plane determined to roll over to the left. I used both arms to pull on the controls and one knee as well for leverage but with no effect. Another second or two and the plane would have been over on its back and into the ground. I prevented this only by slowing it down. At the moment I pulled back on the power there was an automatic temporary compensation of the direction of the plane to the right of the course and, as a result, the timing camera did not catch me on that third pass. That ended the flight. I made a long turn for landing and “Chuck” Yeager, in his chase plane, closed in behind me. He instructed me to leave the throttle untouched as much as possible and to land on the lake bed. I wanted to put the plane down on the runway where the ground crew was waiting but “Chuck” insisted that I put it down on the lake bed where I could take a high-speed landing and a long roll. I took my oxygen mask off and smelled fuel in the cockpit. When the wheels touched ground and the roll had about stopped, “Chuck” told me to cut the throttle and switches and get out as quickly as possible because I had a bad fuel leak which he had seen from his plane. A stream of fuel about the size of one’s thumb was gushing out of the bottom of the main section of the left wing. . . .

The Canadair Sabre Mk.3 was a one-of-a-kind CL-13 Sabre (an F-86E Sabre manufactured by Canadair Ltd. under license from North American Aviation, Inc.) built to test the prototype Avro Canada Gas Turbine Division Orenda 3 engine. Modifications to the F-86 airframe were required to install the new, larger engine.

The Orenda 3 was an axial-flow turbojet engine with a 10-stage compressor, six combustion chambers and single-stage turbine. It produced 6,000 pounds of thrust (16.69 kilonewtons), a 15% improvement over the General Electric J47-GE-13 installed in the standard F-86E. The Orenda was 121.3 inches (3.081 meters) long, 42 inches (1.067 meters) in diameter and weighed 2,650 pounds (1,202 kilograms).

Canadair Ltd. was an aircraft manufacturer located at Cartierville, Montreal, Canada, owned by the American submarine builder, Electric Boat Company. Canadair also built licensed versions of the Douglas DC-4 (powered by Rolls-Royce Merlin engines) and the Lockheed T-33 two-place jet trainer. In 1954, the company became a part of General Dynamics.

After the speed and altitude records, No. 19200 was sent to North American Aviation for evaluation. Today, it is on static display outdoors at Wetaskiwin Regional General Airport (CEX3), Alberta, Canada.

3 June 1946: As part of a series of world record attempts made over a three-day period by the United States Army Air Forces, Lieutenant Colonel Keith S. Wilson, Chief of the Rotary Wing Branch of the Air Material Command at Wright Field, took off at 9:01 a.m., and flew a Sikorsky R-5A helicopter over a 20 kilometer (12.4 statute miles) course. The helicopter completed the course in 6 minutes, 43 seconds. This established a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course of 178.39 kilometers per hour (110.85 miles per hour).¹ This exceeded the previous record which had been set by Ewald Rholfs, 25 June 1937, with a prototype Focke-Wulf 61.²

“CRANING NECKS to see the Sikorsky R-5A helicopter cross the starting line at Wright Field this morning on its way to hanging up a new speed record, these official timers and timer-observers, stand with stop watches in hand. They are (left to right): Stephen Wolfe, W. G. Kiefaber, George Baker, L. L. Custer, official timer; Russell Nichols technical director of National Aeronautic Association (NAA), Lt. Col. R. G., Ruegg, project officerf for all record flights, and Maj. P.G. Atkinson, who holds a similar title in Washington.” (The Dayton Herald, Vol. 67, No. 130, 3 June 1946, Page 1, Columns 4–6)

The National Aeronautic Association official observers of the record flight were Stephern Wolfe, L.L. Custer, and W.G. Kiefaber, timeres; Russell Nichols NAA Technical Director.

Lieutenant Colonel Wilson was awarded the Legion of Merit:

The President of the United States of America, authorized by Act of Congress, 20 July 1942, takes pleasure in presenting the Legion of merit to Lieutenant Colonel (Air Corps) Keith S. Wilson, United States Army Air Forces, for exceptionally meritorious conduct in the performance of outstanding service to the Government of the United States from January 1945 to March 1947.

The Sikorsky R-5A (Model S-48) was a single-engine, two-place helicopter. The cabin was built of aluminum with plexiglas windows. The fuselage was built of plastic-impregnated plywood and the tail boom was wood monocoque construction. The main rotor consisted of three fully-articulated blades built of wood spars and ribs and covered with fabric. The three bladed semi-articulated tail rotor was built of laminated wood. The main rotor turned counter-clockwise as seen from above. (The advancing blade is on the helicopter’s right.) The tail rotor was mounted on the helicopter’s left side in a pusher configuration. It turned clockwise as seen from the helicopter’s left.

The R-5A went into production in July 1945 and more than 300 had been built by the time production ended in 1951.

The helicopter’s fuselage was 41 feet, 7½ inches (12.687 meters) long. The main rotor had a diameter of 48 feet, 0 inches (14.630 meters) and tail rotor diameter was 8 feet, 5 inches (2.565 meters), giving the helicopter an overall length of 57 feet, 1 inch (17.399 meters) with rotors turning. It was 13 feet, 1½ inches (4.001 meters) high. The landing gear tread was 12 feet (3.7 meters). The R-5A had an empty weight of 3,780 pounds (1,715 kilograms) and maximum takeoff weight of 4,900 pounds (2,223 kilograms). Fuel capacity was 100 gallons (378.5 liters).

The helicopter was powered by an air-cooled, supercharged, 986.749-cubic-inch-displacement (16.170 liter) Pratt & Whitney Wasp Jr. T1B4 (R-985 AN-5) direct-drive, nine-cylinder radial engine which was placed vertically in the fuselage behind the crew compartment. This engine was rated at 450 horsepower at 2,300 r.p.m., Standard Day at Sea Level. The R-985 AN-5 was 4 feet, 0.00 inches (1.219 meters) long, 3 feet, 10.25 inches (1.175 meters) in diameter and weighed 684 pounds (310.3 kilograms) with a magnesium crankcase.

The R-5 had a maximum speed (Vne) of 107 knots (123.1 miles per hour/198.2 kilometers per hour). Range was 275 miles (442.6 kilometers). The service ceiling was 14,800 feet (4,511 meters). The absolute hover ceiling was 3,000 feet (914.4 meters).

The Société des Avions Marcel Dassault MD.454 Mystère IV N 01 was the first of two prototype two-place, single-engine, swept-wing interceptors. 01 was first flown 19 July 1954 by test pilot Gérrard Muselli. It had a large air-search radar mounted over the intake and was armed with 52 rockets carried in a retractable tray in the belly, very similar to the North American Aviation F-86D Sabre. The fuselage had been lengthened over the single-seat Mystère IV to provide space for the second cockpit.

The Mystère IV N was 49 feet, 11 inches (15.215 meters) long with a wingspan of 37 feet, 6 inches (11.430 meters) and overall height of 15 feet, 1 inch (4.597 meters). Its empty weight was 15,741 pounds (7,140 kilograms) and maximum takeoff weight was 22,572 pounds (10,238 kilograms).

The Mystère IV N was powered by a Rolls-Royce Avon RA.7R axial flow, afterburning turbojet engine. It used a 12-stage compressor, 8 combustion chambers and 2-stage turbine. It produced 9,500 pounds of thrust (42.258 kilonewtons) at 7,800 r.p.m., with afterburner. The engine was 42.2 inches (1.072 meters) in diameter, 276 inches (7.010 meters) long and weighed 2,960 pounds (1,343 kilograms).

Jacqueline Auriol’s record-setting Dassault Mystère IV N 01 F-ZXRM is on display at the Conservatoire l’Air et l’Espace d’Acquitane, Bordeaux Merignac Airport, France.
