Other way around, perhaps? I "read" (my German is very rudimentary)a

history of Schempp-Hirth a few years ago and saw photos of wind
turbine
blades being manufactured some time in the late 50s/early 60s. Does
anybody have any details?

I also understand that a lot of glider wing aerodynamics is actually
a
spinoff from research paid for by wind turbine builders. Eppler, for

one, did turbine work I believe. Again, does anyone know any facts?

Mr Hanle of Glasflugel(Glasswing) was very active in the development of
turbine blades as a parallel activity to many contributions to
developing the art of building sailplanes. Possibly the photos of
blades were taken about the time that S/H was in the process of
absorbing Glasflugel after his death.
