Gomer, is this just managing the TET or is there another aspect to starting the Arriel? I've only got a small amount of piston experience (not that i wouldn't consider going further if cash wasn't so tight at the mo).

Any chance of outlining the difference in op between piston and turbine? I've been told that turbines are more-or-less single control. Have you ever found the TET response limitation to be a problem once airborn?

I left Longbridge (UK) when it became clear i was never going to get the engine design experience i wanted - i'm sure a lot of talented engineers felt the same . There are some lines of research which look extremely promising at overcoming the combustion delay inherent to compression ignition. Once this is achieved 4kW/kg may be achievable from a small high boost turbodiesel. I am reduced now to trying to fit in a design study between other activities.

For sale: One country, slightly downtrodden, by lack government support for long term investments (like education).
