How do you measure the power of a jet engine if not in horsepower? The real metric might surprise you and it explains why ...

More blades, more speed? Not exactly-here's why extra propeller blades don't guarantee higher top speeds for aircraft.

Also, in this paper, an experimental validation study for the above-mentioned propellers is performed using a 3D-printed toroidal Propeller and a market-available standard propeller of the same size.

When propellers rotate non-uniformly, it can create detrimental airflow patterns, leading to a significant drop in the duct's thrust and causing system instability, even if the propellers generate ...

Another aspect of a fair comparison that doesn’t seem to have been published for toroidal propellers is comparing different propellers at the same thrust force.
