I had heard of this propeller in relation to vessel propulsion; tugs
and minesweepers etc. Here's a drawing of the setup:


Wikipedia here:


You can see that where it would-and does- work on a boat where
weight and room aren't a problem however it seems a bit of a
stretch for an aircraft, certainly if configured in a
conventional manner. It's individual blade function in a way
mimics a helicopter rotor blade's angle of attack/rotor tilt
depending on where each rotor blade is in relation to the
direction of flight.
