The remaining challenge:  to make sure that the turbine wheel
can survive the temperature.  We have reasons to believe that
post-combustion may occur at some settings on the wheel blades'
leading edge, with local temperature up to 2000°F.  We have to
have the wheel made in high-temp Ni-alloy.  I hope to have this
done and tested by the end of the year.

Hello Francois,

I presume you are familiar with Comprex charger, since initially it was
Brown Boveri development, and it's current version "Hyprex" is developed
by Swissauto and ETH...

Have you got a chance to investigate it's potential as an aircraft
engine charger?

btw: I added a comprex research paper to collection:
