I’m just waiting to hear that someone has stolen food from a bin at the back of their local supermarket, got food poisoning and then sued the store.

There a number of issues to consider when designing propellers, power delivered by the engine, weight, diameter wrt tip speed, ground clearance and gyroscopic effects, aspect ratio of the blades and probably more I haven’t thought of. A single blade may be more efficient but totally impractical.

Firstly thanks to all the guys that made this possible. ZA147 was the last aircraft I flew in whilst in the RAF on 101 SQN and it brought back a lot of memories from when the Sqn reformed in 1983 through to my departure in 1988. Good to see the old girl up close again and so pleased to hear she is being preserved.

I doubt this will ever happen with fission reactors due to the radiation risks involved, not just in the event of a crash but in everyday handling of isotopes. There is also the weight consideration of a) bio shielding and b) harnessing the heat energy from the reactor.
Even with fusion energy, the heat still needs to be captured and turned into motive power (steam driven electrical generators ? hot air turbines ? ) and although there are no nasty isotopes there would still be a need for a heavy bioshield to stop the nasty neutrons from frying the crew / pax.

All in all too dangerous, too heavy and too costly.
