Compressor
Wheel and part of the diffuser system showing the gap between the
wheel edge and the vanes. This wheel is 80mm inlet size, 128mm
overall diameter and 7.5 mm 'deep' at the edge. Notice balance
cut outs.
New Solent Internal Pictures as it was stripped for painting!
There are lots of large detailed pics on this page and they load together - please be patient! Quality is more important than speed to the guys who are building and running these things.

Comparison
with an old Garret T3 turbocharger compressor wheel, as used by
many model engine builders. And my thumb..
What you see when you
unbolt the front case. The diffuser ring actually faces the other
way, or it wouldn't work!
An ignitor
(OK a spark plug...) There are two of these, but I may not put
them back, instead the holes will be blanked off and the thing
will be ignited with a lighter as we do already.It pokes through
the case and into a hole near the injectors and easily ignites
Kerosene, (finely atomised by the injectors).
This is
what you see if you unbolt the rear case. The injectors (that you
can see sticking out of the back part on the left) inject through
the holes in the combustor. Remember that this is the rear of the
engine, so the air and fuel burned inside the combustor has to do
a 180 degree turn at the front and comes out through the turbine
wheel that you can see here (reverse flow).
