the hangar.

Somehow I missed the fact all these years that is was a variable
vane turbo. Apparently a well kept secret in the turbo charger world.
How I missed this fact I will never know. Perhaps they have good patents
and nobody wants to talk it up. If it works as claimed it will put
all the other turbo guys out of biz.

This unit is ideal for turbo charging an aircraft
engine as you can slow the prop RPM with higher prop pitch
and boost the HP at that RPM with the variable vanes.

It is also ideal for turbo compound.

The convoluted design of the turbine housing leads to a cooler exhaust
impinging on the vanes and the turbine wheel. The bearing oil supply
is also self contained. No engine oil required. One could probably use
turbine oil and have a separate oil cooler system if necessary.

This is a very innovated unit indeed.

"VATN is a series of variable-vanes that optimize the flow area of the turbine
by adapting to the exhaust gases. By doing this, the turbine wheel is able to
operate at peak efficiency throughout a wide RPM range, something that has
never been achieved before. This also eliminates the need for a wastegate,
which conventional turbochargers rely upon to control boost. Instead, the vanes
automatically adjust the flow area and backpressure to perfectly match the
torque requirements of the compressor wheel to produce the desired boost.
Eliminating the need for a wastgate means eliminating extra cost in your turbo
system"
