Fauvel AV.2


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.
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.
