The Abrial A-13 Buse was a tailless glider prototype that was designed in 1954.
It was the last in a series of glider aircraft designed by Georges Abrial.
[1] The glider featured a short fuselage with a single, non-tapered strut-braced straight wing.
The design had been demonstrated by very complete tests carried out on a 1:10 scale model at the Eiffel Laboratory but no full-size version was ever constructed.
