Yes I keep forgetting it was a turbine project originally.As mentioned in the documentation and that I added on the bottom of the spreadsheet, they were 5 Prop blades and 6 Stators.
So conforming to what KIWI303 sais about reduced noise.
is on the fraser page 2 right above those sheets - guessing they're for that version not a lycoming version?The 71X flew with one of the Lycoming piston engines and a 4- bladed wood propeller.
I did a weight analysis of a 400hp class hybrid/ electric fan setup including a 50KWh battery pack and it weighs roughly 1000 pounds more than a TSIO-540 with propeller. This will also come nowhere close in speed to the Lycoming setup. Static thrust is less and the fan efficiency is really low above 200 knots.Electric drive will not be as efficient as gears and shafts. Most likely, more weight and cost, too. So dumb, unless a special application like modest power tip motor/generators. Most of the "Electric Cool-Aid" projects are investor scams. Recreational psychedelics is the future of flight.
Fake jet design is a real challenge. The fan(s) are limited in diameter and the desire for high performance leads to high HP, weighty engines and unfortunately decreasing thrust per HP. Hats off to the developers of a pseudo-jet with reasonable performance. Seaplanes might use ducted props to advantage.

”We‘ve improved this design by putting a turbocharger in front of the compressor, which should bring efficiency in line with the cheaper diesel we will be replacing this with”.He could have done that to the first one, claimed a diesel version was under development and flown until he retires without ever producing anything.
