Franz Xaver Wortmann (September 24, 1921 - January 16, 1985) was a German aerodynamicist.
After World War II, Wortmann spent time as a pilot and observer with the German Air Force.
[1] Together with Richard Eppler and Dieter Althaus, Wortmann carried out ground-breaking work in the late 1950s and the 1960s in the field of development of laminar flow airfoil profiles using the inverse design method.
By the early 1970s, many successful designs of glider had a wing based on a Wortmann profile.
In 1974 Wortmann took over the leadership of the Institute of Aerodynamics and Gas Dynamics at the University of Stuttgart.
