The Fauvel AV.45 was an unorthodox motor glider produced in France in the 1960s and 1970s. Like other Charles Fauvel designs, it was a tailless aircraft, in this case inspired by the work that German firms had done on producing motorised versions of his AV.36 design. The prototype of the AV.45 was an extensively modified AV.36 powered by a two-stroke engine. AV.45s have been built with a number of other engines, however, including at least one aircraft powered by a small turbojet (a ). Falconar marketed the plans in the 1970s.
