21 December 1952: Flying a Société nationale des constructions aéronautiques du Sud-Est-built DH.100 Mistral powered by a Rolls-Royce Nene 104 turbojet engine, Mme Jacqueline Marie-Thérèse Suzanne Douet Auriol set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over 100 Kilometers Without Payload of 855,92 kilometers per hour (531.84 miles per hour).¹

Jacqueline Auriol Sets New Record

     MARSEILLE, France, Dec. 21 (AP)—Jacqueline Auriol, daughter-in-law of the French president, today bettered her own woman’s record for flying over a closed 100-kilometer (62.13 mile) course with an average time of 534.375 miles an hour.

     Mrs. Auriol’s flight today beat the record of 511.360 miles an hour which she set in May, 1951. She flew a “Mistral” jet fighter of the French nationalized aircraft industry, powered by a Nene-Hispano Suiza motor. The previous record had been set with a jet “Vampire.”

     In three passes at the course from Istre military base north of Marseille to Avignon and return, Mrs. Auriol bettered her record on the second try.

     She is the wife of Paul Auriol, son and secretary of the president of the French Republic.

This Day in Aviation has not been able to determine with certainty the exact variant of the SNCASE Mistral that Mme Auriol flew to set this record. The FAI’s online database identifies the aircraft as a “DH.100 Mistral,” but powered by a Rolls-Royce Nene 104 engine. Most contemporary newspaper articles identify the aircraft only as a “Mistral,” and a few, as a “Mistral 76.” So, some speculation is in order.

Initially, Société nationale des constructions aéronautiques du Sud-Est (SNCASE) produced the de Havilland DH.100 Vampire for the Armée de l’air from kits supplied by de Havilland. It went to on to build Vampires based on the FB.5 fighter bomber airframe. SNCASE then developed its own variant, the SE.530 Mistral, which used a Hispano-Suiza-built Rolls-Royce Nene 102 turbojet engine in place of the Vampire’s de Havilland Goblin. (De Havilland designated these fighter bombers as the FB.53 Mistral.) Four SE.530 prototypes were built, followed by 93 production SE.532s. This was further upgraded to the SE.535, which featured enlarged air intakes for the Nene 104 engine, a pressurized cockpit, and a SNCASO ejection seat. It also had an increased fuel capacity. The SE.532s were upgraded to the SE.535 standard. SNCASE built 150 SE.535s.

The 1952 photograph at the head of this article shows Mme Auriol seated in a Mistral with the number 76 painted on its fuselage. Could this be the “Mistral 76” mentioned in the newspaper articles?

Does the number 76 identify this airframe as the 76th of the 93 SE.532s? Since the FAI database states that the engine is a Nene 104, can we further speculate that this 532 has been upgraded to the SE.535 standard?

A French website, FRROM, states that the Mistral flown by Mme Auriol to set the 21 December 1952 speed record was later assigned to 7th Escadres de Chase.

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.

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.
