14 May 2005: Test pilot Didier Delsalle landed a Eurocopter AS 350 B3 Écureuil, c/n 3934, registration F-WQEX, at the summit of Mount Everest, the highest point on Earth, at 8,848 meters (29,029 feet).

The Fédération Aéronautique Internationale required that the helicopter remain on the summit for at least two 2 minutes for the landing to be considered official. Delsalle actually landed on the summit twice, staying four minutes each time. The flight set two world records for the highest take-off. ¹ At the summit, the wind was blowing 65 knots (75 miles per hour/120 kilometers per hour), and there were severe updrafts and downdrafts. The air temperature was -35 °C. (-31 °F.).

Delsalle said that on the upwind side, even with the helicopter’s collective fully down to reduce power and lift, the As 350 continued to gain altitude. On the downwind side, the winds blew him away from the summit, and at full power, he was unable to counteract that.

The most difficult problem, though, was that when over the summit, the mountain drops away in every direction. Delsalle had no visual referent to guide him to the surface.

These records broke Delsalle’s previous records for highest take-off, 7,927 meters (26,007 feet), set just two days earlier. ²

During flight tests to evaluate the practicality of the Everest flight, on 14 April 2005, Delsalle and the AS 350 set three time to climb world records over Istres, France. The Écueriel climbed to a height of 3,000 meters (9,843 feet) in 2 minutes, 21 seconds; 6,000 meters (19,685 feet) in 5 minutes, 6 seconds; and 9,000 meters (29,528 feet) in 9 minutes, 26 seconds. ³

Delsalle also rescued two Japanese climbers at 16,000 feet (4,877 meters).

Didier Delsalle was born 6 May 1957, at Aix-en-Provence, France. He joined the Armée de l’Air (French Air Force) in 1979, and was trained as fighter pilot. In 1981 he transitioned to helicopters and was assigned to search-and-rescue operations. After twelve years military service, Delsalle became an instructor at École du personnel navigant d’essais et de réception, the French test pilot school at Istres, France. He then became the chief test pilot for light helicopters for Eurocopter, and later for the NH90 medium helicopter.

Delsalle holds seven FAI world records, five of which remain current.

The Eurocopter AS 350 Écureuil is a  6–7 place, single-engine light helicopter, operated by a crew of one or two pilots. (It is known as the A-Star in the United States.) Introduced by Aérospatiale in 1975, it remains in production today and is one of the most popular civil helicopters. The manufacturer is now known as Airbus Helicopters.

Eurocopter AS 350 B3 Écureuil F-WQEX. (Airbus Helicopters)

The AS 350 B3 is a high-performance variant, widely used in law enforcement. The overall length with rotors turning is 12.94 meters (42 feet, 5.4 inches). The fuselage is 10.93 meters (35 feet, 10.3 inches) long and the cabin is 1.87 meters (6 feet, 1.6 inches) wide. The helicopter’s overall height is 3.14 meters (10 feet, 3.6 inches).

In keeping with standard French practice, the Écureuil/A-Star’s main rotor system turns clockwise as seen from above. (The advancing blade is on the helicopter’s left side.) The fully-articulated the three-blade rotor has a diameter of 10.69 meters (35 feet, 0.9 inch). The normal operating range is 385–394 r.p.m. (320–430 r.p.m. in autorotation). A two-bladed tail rotor is mounted on the right side of the tail boom in a pusher configuration. It rotates clockwise, as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.) Its diameter is 1.86 meters (6 feet, 1.2 inches.)

The AS 350 B3 has an empty weight of approximately 1,174 kilograms (2,588 pounds), depending on installed equipment, and maximum gross weight of 2,250 kilograms (4,961 pounds)

The AS 350 B3 variant is powered by a single Turboméca Arriel 2B turboshaft engine. The Arriel 2B is a free turbine turboshaft engine which uses an electronic engine control system (EECU). The engine has a two-stage compressor section (single-stage low-pressure axial flow, single-stage high-pressure centrifugal flow); an annular combustion chamber; and two-stage turbine section (single-stage gas generator and single-stage power turbine). The compressor section turns 52,110 r.p.m. at 100% N1; The power turbine, N2, turns 39,095 r.p.m. at 100%. A gear reduction unit reduces the engine’s output shaft speed to 5,990 r.p.m.

The Arriel 2B produces 847 shaft horsepower, but is de-rated to the helicopter’s main transmission limit. Installed, the Arriel 2B is rated at 536 horsepower for cruise; 700 horsepower, Maximum Continuous Power; and 733 horsepower for take off (5 minute limit).

The Arriel 2B is 118.0 centimeters (3 feet, 10.46 inches) long, 50.0 cm (1 foot, 6.69 inches) wide, 62.0 cm (2 feet, 0.41 inches) high. It weighs 134 kilograms (295.4 pounds), dry. The Arriel series engines are now produced by Safran Helicopter Engines.

12 May 1951:  Mme Jacqueline Marie-Thérèse Suzanne Douet Auriol flew a Goblin-powered de Havilland DH.100 Vampire to set a Fédération Aéronautique Internationale (FAI) world record for speed over a given distance of 100 kilometers (62.14 statute miles), averaging  818.18 km/h (505.39 m.p.h.). ¹ Mme Auriol  took off from Istres, flew to Avignon and back. She broke the existing record, 703.38 km/h (437.06 m.p.h.) set 29 December 1949 by Jacqueline Cochran of the United States with a North American Aviation P-51C Mustang. ²

The Chicago Tribune reported:

MRS. AURIOL, 33, PILOTS PLANE AT RECORD 507 MPH

Breaks Women’s Mark of Jacqueline Cochran

     ISTRES AIRFIELD, Marseilles, France, May 12—[Reuters]—Mrs. Jacqueline Auriol, daughter-in-law of the French president, Vincent Auriol, today officially smashed the American held 100 kilometer [62.5 miles] air speed record for women.

     Mrs. Auriol, blue eyed mother of two children, flew the Istres-Avignon return course at an official speed of 818.558 kilometers an hour [about 507 miles].

     Thus she broke the three year old record of Jacqueline Cochran, who flew the distance at Coachella Valley, Cal., in a P-51 Mustang, powered by a Rolls-Royce piston engine, of 469 m.p. h.

     Mrs. Auriol established the new record in a French built Vampire jet, named “Mistral” after a prevailing French wind. The ship has two British De Havilland Gobling [sic] turbo-compressors.

Trial Run Even Faster

     At a trial run this morning Mrs. Auriol went even faster, covering the course at 509½ m.p.h. After the morning test run, Mrs. Auriol said she hadn’t “pushed” he aircraft at all. The French makers claim it can reach 567 m.p.h.

     Mrs. Auriol, 33, is slim, boyish, has her hair cut short and usually wears slacks. She studied painting, but gave it up after her marriage in 1938 to Paul Auriol, private secretary to his father.

     Her face bears the marks of a flying accident in which she nearly lost her life two years ago. She was co-piloting a seaplane which crashed into the Seine.

Holds U. S. Pilot License

     She spent a year in hospital in France before going to the United States to complete her treatment, which included 22 operations. Four eight months she had to be fed artificially.

     She learned to pilot a helicopter at Buffalo, N. Y., and passed her pilot test over Niagara Falls. She learned jet piloting in a Meteor with Test Pilot Raymond Guillaume, who was present today and made a test flight over the course before her record attempt.

Chicago Sunday Tribune, Vol. CX, No. 115, 13 May 1951, Part 1, Page 29, Column 1

For her record flight, Mme Auriol was named Chevalier de la légion d’honneur. Harry S. Truman, President of the United States, presented her with the Harmon International Aviatrix Trophy.

The DH.100 was a single-seat, single-engine fighter powered by a turbojet engine. The twin tail boom configuration of the airplane was intended to allow a short exhaust tract for the engine, reducing power loss in the early jet engines available at the time.

Société nationale des constructions aéronautiques du Sud-Est (SNCASE) assembled knocked-down kits of de Havilland DH.100 Vampires before entering into licensed manufacture of its own SE.530 Mistral.

The fighter variant, the DH.100 F1, was armed with four 20 mm guns.

The Goblin is a linear descendant of the early Whittle units. It comprises a single-sided centrifugal compressor delivering air to sixteen combustion chambers grouped symmetrically around the axis of the unit and leading to the nozzle of the single-stage axial turbine which drives the compressor. Compressor impeller and turbine rotor are coupled by a tubular shaft to form a single rotating assembly which is mounted on only two ball bearings. The maximum diameters of the engine, around the compressor casing, is 50in., [1.27 meters] and with a jet pipe of minimum length fitted the overall length is about 8ft. [2.438 meters] Equipped with a jet pipe and all the necessary engine auxiliaries the dry weight of the complete unit is 1,500 lb. [680 kilograms] Fuel consumption is at the rate of 1.23 lb. / hr. per lb. thrust.

FLIGHT and AIRCRAFT ENGINEER, No. 1923. Vol. XLVIII. Thursday, 1 November 1945 at Page 472, Column 2

The Vampire entered service with the Royal Air Force in 1945 and remained a front-line fighter until 1953. 3,268 DH.100s were built. The SE.530 Mistral served with the Armée de l’air from 1952 to 1961. SNCASE had assembled 67 Vampire FB Mk 5 kits and built 120 SE.530 Mistrals.

11 May 1964: At Edwards Air Force Base, California, Jacqueline Cochran flew a Lockheed F-104G Starfighter, 62-12222, to 2,300.23 kilometers per hour (1,429.30 miles per hour)—Mach 2.16—over a straight 15 to 25 kilometer course. She was the first woman to fly faster than Mach 2 and she set a new Fédération Aéronautique Internationale (FAI) World Speed Record. ¹

Jackie Cochran wrote about flying the 15/25 kilometer straight course in her autobiography:

Picture in your mind a rectangular tunnel, 300 feet high, a quarter of a mile wide, and extending 20 miles long through the air at an altitude of 35,000 feet. I had to fly through that tunnel at top speed without touching a side. There were no walls to see but radar and ground instruments let me know my mistakes immediately. Up there at 35,000 feet the temperature would be about 45 degrees below zero. Not pleasant but perfect for what I was doing. Inside the plane you are hot because of the friction of speeding through the air like that. The cockpit was air-conditioned, but when you descend, things happen so fast the plane’s air-cooling system can’t keep up with it. I was always hot and perspiring back on the ground.

Jackie Cochran: An Autobiography, by Jacqueline Cochran and Maryann Bucknum Brinley, Bantam Books, New York 1987, Page 314.

Cochran set three speed records with this F-104G in May and June 1964. Under the Military Assistance Program, the U.S. Air Force transferred it to the Republic of China Air Force, where it was assigned number 4322. It crashed 17 July 1981.

The F-104G was the final production version of the Lockheed Starfighter. Rather than an interceptor, the G-model was a fighter bomber, with a strengthened fuselage and wings, and hardpoints for carrying bombs and additional fuel tanks. Built by Lockheed, they were also licensed for production by Canadair, Dornier, Fiat, Fokker, Messerschmitt and SABCA.

The F-104G was a single-seat, single engine fighter bomber, 54 feet 8 inches (16.662 meters) long with a wingspan of just 21 feet, 9 inches (6.629 meters) and overall height of 13 feet, 6 inches (4.115 meters). The empty weight is 14,000 pounds (6,350.3 kilograms) and loaded weight is 20,640 pounds (9,362.2 kilograms).

The F-104G was powered by a General Electric J79-GE-11A engine, a single-spool, axial-flow, afterburning turbojet, which used a 17-stage compressor section and 3-stage turbine. The J79-GE-11A is rated at 10,000 pounds of thrust (44.48 kilonewtons), and 15,800 pounds (70.28 kilonewtons) with afterburner. The engine is 17 feet, 4.0 inches (5.283 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighed 3,560 pounds (1,615 kilograms).

The maximum speed is 1,328 miles per hour (2,137.2 kilometers per hour). It has a combat radius of 420 miles (675.9 kilometers) or a ferry range of 1,630 miles (2,623.2 kilometers) The service ceiling is 50,000 feet (15,240 meters).

Armament consists of a 20 mm General Electric M61A1 Vulcan six-barreled Gatling gun, with 725 rounds of ammunition. Up to four AIM-9 Sidewinder air-to-air heat seeking missiles can be carried on the wingtips or under wing pylons. In place of missiles, two wingtip fuel tanks and another two under wing tanks could be carried.

On NATO alert, the F-104G was armed with a B43 variable-yield nuclear bomb mounted on the fuselage centerline hardpoint. The B43 could be set for explosive force between 170 kilotons and 1 megaton.

8–19 May 1946: Over an 11-day period, 20th Air Force Boeing B-29 Superfortresses based in the Marianas Islands set a series of twelve payload, altitude and speed records. These records were certified for the Fédération Aéronautique Internationale (FAI) and National Aeronautic Association (NAA) by Charles S. Logsden, the association’s official timer and records keeper. All of the record flights originated from Harmon Field on the Island of Guam.

Harmon Field, 24 January 1945. (NARA/U.S.Navy 80-G-346042)

On 8 May, a B-29 flown by Arthur A. Pearson carried a 10 000 kilogram (22,046 pounds) payload to an altitude of 12 668 meters (41,562 feet). [FAI Record File Number 10415] Other members of the flight crew were Vernon L. Dalbey, R.S. Strasburg, I. F. Bork, J.T Collins, and J. Friedberg.

Finally. on 19 May 1946, J.D. Bartlett, with his crewmen, William Murray, C.M. Youngblood, Don J. Shrader, and R.F. Wilson, flew their Superfortress around a closed circuit if 1 000 km (621.37 mi.) with a payload of 10 000 kg (22,046 lbs.) at an average speed of 575,71 km/h (357.730 m.p.h.); [FAI # 10408]; and 2 000 km (1,243.74 mi.) at 574,59 km/h (357.034 m.p.h.) (FAI # 10409]

Boeing B-29-1-BN Superfortress 42-93843, the final Block 1 Superfortress, circa 1944.

The B-29 Superfortress was the most technologically advanced—and complex—aircraft of World War II. It required the manufacturing capabilities of the entire nation to produce. Over 1,400,000 engineering man-hours had been required to design the prototypes.

The Superfortress was manufactured by Boeing at Seattle and Renton, Washington, and Wichita, Kansas; by the Glenn L. Martin Company at Omaha, Nebraska; and by Bell Aircraft Corporation, Marietta, Georgia.

There were three XB-29 prototypes, 14 YB-29 pre-production test aircraft, 2,513 B-29 Superfortresses, 1,119 B-29A, and 311 B-29B aircraft. The bomber served during World War II and the Korean War and continued in active U.S. service until 1960. In addition to its primary mission as a long range heavy bomber, the Superfortress also served as a photographic reconnaissance airplane, designated F-13, a weather recon airplane (WB-29), and a tanker (KB-29).

The B-29 was operated by a crew of 11 to 13 men. It was 99 feet, 0 inches (30.175 meters) long with a wingspan of 141 feet, 3 inches (43.068 meters). The vertical fin was 27 feet, 9 inches (8.305 meters) high. The airplane’s empty weight was 71,500 pounds (32,432 kilograms). Its maximum takeoff weight of 140,000 pounds (63,503 kilograms).

The B-29’s wings had a total area of 1,720 square feet (159.8 square meters). They had an angle of incidence of 4° and 4° 29′ 23″ dihedral. The leading edges were swept aft to 7° 1′ 26″.

The B-29 was powered by four air-cooled, turbocharged and supercharged, 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Cyclone 18 (also known as the Duplex-Cyclone) 670C18BA4 (R-3350-23A) two-row, 18-cylinder radial engines. These had a Normal Power rating of 2,000 horsepower at 2,400 r.p.m., and 2,200 horsepower at 2,800 r.p.m., for takeoff. They drove 16 foot, 7 inch (5.055 meter) diameter, four-bladed, Hamilton Standard constant-speed propellers through a 0.35:1 gear reduction. The R-3350-23A was 6 feet, 4.26 inches (1.937 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,646 pounds (1,200 kilograms).

The maximum speed of the B-29 was 353 knots (406 miles per hour/654 kilometers per hour) at 30,000 feet (9,144 meters), though its normal cruising speed was 216 knots (249 miles per hour/400 kilometers per hour) at 25,000 feet (7,620 meters). The bomber’s service ceiling was 40,600 feet (12,375 meters) and the maximum ferry range was 4,492 nautical miles (5,169 statute miles/8,319 kilometers).

The Superfortress could carry a maximum of 20,000 pounds (9,072 kilograms) of bombs in two bomb bays. For defense, it was armed 12 Browning AN-M2 .50-caliber machine guns in four remote, computer-controlled gun turrets and a manned tail position. The bomber carried 500 rounds of ammunition per gun. (Some B-29s were also armed with an M2 20 mm autocannon at the tail.)

A number of B-29 Superfortresses are on display at locations around the world, but only two, the Commemorative Air Force’s B-29A-60-BN 44-62070, Fifi, and B-29-70-BW 44-69972, Doc, are airworthy. (After a lengthy restoration, Doc received its Federal Aviation Administration Special Airworthiness Certificate, 19 May 2016.)

Wright Aeronautical Division XF3W-1 Apache, Bureau of Aeronautics serial number A7223, was a prototype for a single-place, single-engine fighter for the U.S. Navy. The XF3W-1 was a single-bay biplane with a fuselage constructed of steel tubing, covered with doped fabric. The wings were constructed of wood. It was 22 feet, 1 inch (6.731 meters) long with a wingspan of 27 feet, 4 inches (8.331 meters) and height of 8 feet, 6 inches (2.591 meters). It had an empty wight of 1,414 pounds (641 kilograms) and gross weight of 2,128 pounds (965 kilograms). Only one XF3W-1 was built.

The XF3W-1 was designed to use the new air-cooled, supercharged 1,176.036-cubic-inch-displacement (19.272 liters) Wright Aeronautical Division R-1200 Simoon 9-cylinder radial engine, which was rated at 350 horsepower at 1,900 r.p.m. The R-1200 weighed 640 pounds (290 kilograms).

After taking delivery of the prototype, the Navy installed the number two Pratt & Whitney Wasp A engine. (The XF3W-1 was the first airplane to fly with a Pratt & Whitney Wasp engine, 5 May 1926.) The Wasp A was an air-cooled, supercharged, 1,343.8-cubic-inch displacement (22.021 liters) nine-cylinder radial direct-drive engine with a compression ratio of 5.25:1. It was rated at 410 horsepower at 1,900 r.p.m. at Sea Level, burning 58 octane gasoline. The Wasp A was 3 feet, 6.63 inches (1.083 meters) long, 4 feet, 3.44 inches (1.307 meters) in diameter, and weighed 745 pounds (338 kilograms).

The National Advisory Committee for Aeronautics (NACA) used the XF3W-1 for engine and cowling tests at the Langley Memorial Aeronautical Laboratory (LMAL), Langley Field, Hampton, Virginia. Which engine was installed at the time of Lieutenant Soucek’s record flight is uncertain.

The XF3W-1’s engine was supercharged by a NACA Model 2E Roots-type supercharger, built by the Allison Engineering Company. This supercharger, serial number 1, is in the collection of the National Air and Space Museum.

The XF3W-1 was also configured as a float plane.
