And the million dollar question is, what kind of project is it you are working on?  |

I use those engines to build a solar thermal power plant.
I found a way to make them run on hot clean air.
Nothing special, even Leonardo Davinci knew how...
The first one I bought is running on jet-A1 in a test configuration.
I added some components (outlet diffuser described in NASA documents from 30 years ago) and lowered the fuel consumption by approx 20%.
Now i need some high temperature heat exchangers for gas turbines.
Problem is the 800°C, most existing ones don't meet these requirements.

Hi
LOL........you must have done a lot more than just add a diffusing exhaust to get a 20% reduction in fuel usage , a diffusing exhaust might pickup a couple of percentage points on turbine efficiency but thats about all .
800 deg C , gunna need stainless , have you looked at steam superheaters ??
Cheers
John

Indeed more was done than just that...
love to talk about it, but it will have to wait until commercialized.
