Subject: Yes, an Autorotor and Aerodyne are different

Hi everyone,

        Included in a tidal wave of mail on the Autorotor were a number of
questions regarding confusion about the Aerodyne and Autorotor.  For those
just getting their feet wet in this subject area here are the basic
definitions.  The Aerodyne is a variable vane turbo.  Its variable vane
design allows it to avoid most of the "lag" usually associated with turbos.
As a turbo it is driven by exhaust gases.  The Autorotor is a
supercharger--driven off the crank wheel by a belt like your airconditioning
compressor.
