Yes, that's a turbo charged engine. But in sailplanes, the term "turbo"
has a different, historical developed meaning. At the time the term was
introduced, "turbo" was a synonym for "better", "extra" etc. Hence the
term "turbo" was used for sailplanes with a sustainer. That's the whole
story. Technically as wrong as it can be, but who cares.

"turbo" applies perfectly well to a propellor ("turbine" in many
languages).

Given where they come from, if they were what we call "turbocharged" it
would proabbly say "Kompressor".
