From the development to the birth of the AV-22 was an extremely long time. In 1946, Charles Fauvel had exhibited during an aviation convention in Paris a tandem two-seat glider project, under the title “glider for multiple uses”. This project was based on a survey from 1938, that foresaw the possiblity of transforming a two-seat glider to a single-seater able to takeoff by itself using a small front fuselage-mounted engine, and an economical two-seat side-by-side motorglider that would use the same wings but a different fuselage equipped with a heavier, more powerful tractor engine.
The project was not approved and it had been necessary to wait until 1956 for the AV-22 to see the light of day, thanks to funds brought in by the sales of the AV-36 produced by Wassmer. ..The craft had its first flight on April 5, 1956, and was proposed to the official government services immediately, where it was put in competition with the glider Bréguet 902. The following year, the second prototype continued tests. It was equipped with very efficient Schempp-Hirth type air brakes and had a tow hook in the nose of the fuselage, mounted in a high location so as to maintain a better axis in towed flight.
The landing gear was composed of a retractable center wheel and a fixed skid. The wing was removable in two parts, the spars capable of being quickly installed using lever actuated attach pins. The top of the fuselage, as well as the nose, were achieved in fiberglas, while the plexiglas canopy was moulded by Sud-Aviation in Marignane (now known as Matra-Aérospatiale). The AV-22 had a ventilator pickup located in its nose and ventilation was completed by exiting through side windows in the canopy.
Four AV-22’s were constructed, the first made its first flight to Cannes on March 26, 1959. It was delivered to the aeroclub of St Auban on April 14. It is interesting to note that the exhibition at the rally of LeBourget on June 15, 1959 featured the AV-22 performing aerobatics. Towed to 1000 meters, Charles Fauvel demonstrated multiple loops and wingovers, finishing with a low pass at 22O km/h.
The AV-22 had good flight qualities and a very good glide ratio (L/D) compared to other well respected gliders of its time. It demonstrated good air penetration and excellent maneuverability. It was however not the winner chosen by an official group supervising the competition to pick a new glider for aeroclubs. Instead, the “Bijave”, an existing glider design produced by the Wassmer Company, was chosen mainly because of two reasons : it was a more classic glider design and the Wassmer company had the ability and capacity to build it in larger numbers.

As a result of his experience with the AV-3, Charles Fauvel began to think about a new improved prototype. World War II didn’t immediately allow him to realize his objective, but once the conflict was over, he resumed his quest at the Société Aéronautique du Rhône, near Bourg-lès-Valence with his newest prototype, the AV-17. The aircraft was destroyed in its first flights. According to Charles Fauvel, the glider had not been constructed correctly; as the cause of the accident was neither the fault of the pilot nor did it discourage Fauvel in pursuit of his flying wing design formula. Fauvel, having raised serious doubts about the AV-17’s construction, was convinced that the blame for the crash should be placed upon the Société Aéronautique du Rhône, the constructor. Although the AV-17 never flew again, the experience gained was a great contribution to the development of later designs by Charles Fauvel.
The single-place AV.17, commonly called “la godasse” (the “shoe”) on the flying fields, was primarily a light machine intended for amateur construction. Its success was certainly due to the fact that almost 300 sets of plans were sent to more than 16 countries and it is reasonable to imagine that about 150 machines have flown.

This project was designed as a successor to the AV-10. Many improvements were incorporated into this new design. But the war stopped the development of this machine and it remained a project on the drawing board. The construction of an improved version, the AV-141, was studied in 1947 and a construction started at Estang-Aviation, in Marseilles, in July 1949. But this construction was never completed.

In 1935 Fauvel flew the AV-10, a light two-seater touring craft with a Pobjoy engine. Concentrating his efforts on this machine, Fauvel improved its performance, and in 1937 the AV-10 took the world altitude record in its category, while becoming the first flying wing to receive a Certificate of Navigability.
The AV-10 was the first airplane-only design of Fauvel to be flown. Designed as a two-seater side-by-side and equipped with a Pobjoy engine of 75 Horsepower, it first flew in 1935. It was exhibited at the 25th Salon de L’Aéronautique at the Grand-Palais of Paris, on the 13th to the 29th of November, 1936, along with other light planes of the era : the Salmson Cricri, the Potez 60, the Leopoldoff Colibri and the Peyret Taupin. In 1937, the AV-10 set a new altitude record for it’s category when it reached 5791 meters, and became the first government-certified flying wing. The AV-10 remained a unique prototype, allowing Charles Fauvel to expand his knowledge and expertise in designing flying wings. The AV-10 disappeared in 1940, when it was taken by German troops.

With the unexpected bankruptcy of the Guerchais enterprise and the end of financial support from the main investor, the Makhonine company, the development of the AV-2 stopped and was ultimately never finished. In a parallel effort, Charles Fauvel designed another prototype, a pure glider designated the AV-3. Thanks to the financial support of friends (former squadron friends), he was able to construct and test the AV-3, making the first flights in 1933 from the La Banne d’Ordanches airfield. He also allowed a famous glider pilot, Eric Nessler, to fly the glider, who confessed that he was very much impressed by Fauvel’s flying wing formula. The AV-3 was destroyed in 1936, when the aircraft hangar where it had been stored for the winter was virtually destroyed by a storm that took off the roof. This allowed rain to fall in torrents on the glider for more than a week and the water caused too much damage to consider repair. The AV-3 was the last pre-war glider of Charles Fauvel.

Charles Fauvel modified an Abrial airfoil section for his projects (the Abrial / STAé 230-231, thickened to 17%) and Georges Abrial helped him for the development of his AV-2. The Abrial reflex airfoils were very efficient and the various tests at the St Cyr wind tunnel gave enough data to use them successfully for tailless aircraft.
Charles Fauvel decided, after having obtained a patent on his formula for the flying wing, to put into work a prototype incorporating his theories. The designation was AV-2 (“AV” for Aile Volante, French for Flying Wing), the AV-1 having been intended only as the model to study the formula in laboratory studies. The construction of the AV-2 started about the year 1932, and the work was performed at the Guerchais factory. Equipped with a self-stabilizing airfoil designed and drawn by Georges Abrial, this aircraft was aimed at amateur pilots of motorized flight as well the glider pilot. The engine, mounted on a pylon on top of the back of the fuselage, could be disassembled from the craft in a few minutes to transform the plane into a pure glider.

Born 31 December 1904 at Angers, Charles Fauvel was attracted to aviation from an early age. From 1913 on, he built models, and Garros and Audemar’s acrobatic competition at Angers in 1914 permanently sealed his passion for aviation. He passed his latin-science-philosophy baccalaureat, then obtained a military flight training scholarship in 1923; he then entered the French Air Force Academy. In 1925 he witnessed his first soaring competition at Vauville, during which Alfred Auger officially beat the glider altitude record using the Peyret-Abrial “Vautour” with more than 700 meters. The same year, during his military service at Chateauroux, he made the acquaintance of Pierre Massenet, with whom he later participated in the foundation of the Club Aéronautique Universitaire (University Aero Club), one of the most renowned soaring clubs of the pre-1940 period.
It was also in 1928 that Fauvel, watching the new Summer soaring competition at Vauville, formed his first flying wing concepts. Observing certain gliders with long, thin wings (Peyret-Abrial “Rapace”, Wolf Hirth…), he considered that to reduce parasitic losses to a minimum, one cannot indefinitely increase the aspect ratio of the wings. Reducing the size of the fuselage and the interaction with the horizontal empennage thus led to the “flying wing” formula, for which Fauvel registered a patent in 1929. Unlike the projects conceived at about the same time in Germany by the Horten brothers and by Lippisch, the work of Charles Fauvel, based on studies and experiments of Georges Abrial and René Arnoux, involved the use of a “stable” airfoil section providing both lift and stabilization, without recourse to a swept and twisted wing as on the German gliders.
Still in 1928, toward the end of the year, Charles Fauvel put the finishing touches of a small light single-seater, the Peyret-Mauboussin PM-10, equipped with a 34 hp Scorpion ABC engine, whose best glide ratio was nearly 16 without engine fairing or wheel pants. It was with this machine that he beat, in September 1929, several international records in the under-400 kg category, including the international altitude record (5,193 meters) and the duration record (12 hours). In 1929, Fauvel participated in the creation of AVIA with Massenet, Auger and a few friends; this was a committee founded to promote the development of soaring. He then left the air force to join AVIA as sport director, while remaining chief pilot of the CAU. He prospected and discovered the airfields of Beynes (near Paris) and of la Banne d’Ordanche (in Auvergne). In the same period he received and perfected the single-seat AVIA 10 A designed by Jarlaud at the Béchereau works. In 1931, he had to leave AVIA, which was suffering financial difficulties, and re-enter the Air Force as a test pilot at the Villacoublay flight test center, until 1933. While on leave, he participated in the Vauville competition in 1931 in the AVIA 32 E, and managed the best French distance of the competition. In 1932, he passed his C license (no. 19) at la Banne d’Ordanche, on the AVIA 15 A.
He then threw himself into the design of his first machine, the AV-1, followed by the AV-2, then by the first pure glider, AV-3, which appeared in 1933. In 1935 he flew the AV-10, a light two-seater touring craft with a Pobjoy engine.
In 1940, Germany invaded France. Charles Fauvel was reassigned to Morocco a deputy group commander. Returning to France after the armistice, he passed in 1941 his instructor’s license at the Montagne Noire center, and was appointed chief of the military soaring center at Avignon. After the invasion of the free zone, he retired from the Air Force with the rank of lieutenant colonel. In May 1945, he was working at the air sports studies technical establishment at Castelnaudary.
In 1954, Charles Fauvel started his own enterprise, the SURVOL company, at Cannes, whose purpose was to promote and facilitate the commercialization of his flying wings.
In 1971, Charles Fauvel decided to stop commercial production of his gliders, but continued to distribute stacks of drawings to amateur builders. The Survol company offered the AV-361, the AV-451, as well as touring craft such as the AV-60. From 1972 on he was president of the Fayence soaring center and also participated in the OSTIV (Organisation Scientifique et Technique du Vol à Voile) congresses, notably in 1978 at Chateauroux, where he presented his report on the flying wing design formula. He died on 10 September 1979 at the controls of his airplane, a Gardan “Super Cab”, which struck the Alps at 735 meters altitude north of Genoa, in Italy.
Recipient of the Croix de Guerre 40-45, Officer of the Legion of Honor, Médaille d’Outre-mer (Overseas Medal) 1926-1927, Aeronautical Medal, Grand Silver Medal of the Aéro-club de France, Grand Gold Medal of the FFVV, Charles Fauvel flew more than 200 different types of airplane and 50 types of glider.

The Faure Monoplane was designed and built by Faure in France, around 1909.
