DG goes the sustainer option.

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.

Somewhere - I must get round to throwing it out - I have a PC with a
"Turbo" button which runs the 386 inside it at an amazing 16MHz (12MHz
otherwise).

The original PC "turbo" buttons ran the machine at 8 MHz instead of 4.77
MHz!!

"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".

Whoops. Looks like I may not have quite such a star performer as I
thought...

No. In German, Kompressor is used for a mechanically driven charger,
turbo for the exhaust driven charger.

Stefan

Errr, no. There is even a famous upperclass car manufacturer who uses the
word "Kompressor" for turbo-charged engines.

Well, to be as correct as I can be:

"Kompressor" is the German word for, you guessed it, a compressor. So to
call a turbo charged engine a Kompressor charged one is, strictly
technically spoken, correct.

Historically, though, the first cars with charged engines had
mechanically driven compressors (driven by the crankshaft). They were
called Kompressor engines.

Then came the charged engines where the compressor was driven by the
exhaust stream. They were called turbo charged engines, just to
distinguish. Technically spoken, the "cold" side of the turbo charger is
a compressor, too, of course. I should be surprised if any marketing
guiy understands this.

Oh, and then came the sailplanes with a sustainer. They are called turbo
sailplanes, to distinguish them from self launchers. It's a crazy world
out there.

Well, the exact technical term in German is "Verdichter" (which is also how
the compressor stages in a turbojet engine are called).
But that doesn't sound very sexy to the marketing guys, and the sailplane
"turbo" has a another context as already mentioned...

In the US, a belt driven compressor is called a "supercharger". In drag
racing its called a "blower", the engine is refered to as a "blown"
engine, cause that's what you end up with. ;-)

turbocharged here too.

They may call them turbo, but they sound like sewing machines to me. :-)
