You're mistaken. Prop speeds are comparable between piston and turbine engines. Bigger, slower moving props are preferable. When prop tip speeds approach the transonic region, on either turbine or piston power plants, efficiency goes south.
- iSnow 11y agoIs this why on the Antonov-70 and the military Airbus, they have those strange curved multi-blade props?
- ckozlowski 11y agoThe curving of the blades I don't think is intended to support faster blade speeds at all, but rather scoop air more efficiently. Computer modeling has enabled designers to develop much more advanced blade designs. And BuffloBagel is right, I got that part wrong. I think what I was trying to say is that a turboprop supports faster aircraft speeds than a traditional engine. But yes, the propeller remains subsonic.

But I think it's the only production aircraft with them. Also, it's loud as hell. https://en.wikipedia.org/wiki/Tupolev_Tu-95 https://en.wikipedia.org/wiki/Tupolev_Tu-95
