Name that Flying Machine
Yes, the staggeringly complex Napier Nomad I. One propeller driven by a turbo-supercharged two-stroke diesel and the other by the rotating parts of a turboprop, driven by the exhaust gas.

Quemerford,
My profound apologies. I see you were the first Nomad in line!
You take precedence.

Ah, so it's a chopper!

An EVA-XC ..................... there was an article on electric aircraft in some magazine on battery technology a while back
"At only around 150 miles (240 kilometers), the maximum range of Ava is limited. However, around the time of his cross-country flight, Clark also intends to unveil a production eVTOL model, which he said will be different in appearance and capable of flying much farther — up to 290 miles (465 kilometers).
Flying these aircraft will require different approaches to performance and flight planning. In a conventional helicopter or airplane, performance increases over the course of a flight as fuel is burned off, decreasing the aircraft’s weight. In an eVTOL aircraft, however, the weight remains constant during flight and power capacity degrades as the batteries approach a low state of charge."
he uses a bus to drive along behind it to charge it when it lands..............

Thanks - it was such a memorable machine in the original article it came back pretty quickly..............
here's another (not electrically powered)
