Hi all,

Wanting to get more knowledge about an aircraft piston engine supercharger, does any have or know where to find an internal picture of a supercharger with parts shown on a diagram ie the compressor/inlet etc....?

Thank you.

A fine point perhaps, nevertheless...the diagram is that of a turbosupercharger, not a 'supercharger.'

Of course, perhaps turbo is what the original poster intended...:rolleyes:

Downwind. If you look at the Turbo-charger depicted in the post from aditya104, the difference between a gear driven supercharger and the turbo charger is that the impeller/impellers is/are driven by exhaust gasses driving a turbine in the turbocharger application. The induction air stream is still ambient air drawn in and compressed which may or not then pass through an inter-cooler. Have a look at a RR Merlin engine or a Pratt & Whitney R1830 to see a couple of "Supercharger" installations. These are geardriven type superchargers.
