Wingtip Propeller Theory
There have been a number of studies of how efficient putting propellers on the wing tips would be. We will try to collect some good ones here.
Below is a video of a simulation:
Below is a list of papers:
- Analysis and Design of a Small-Scale Wingtip-Mounted Pusher Propeller
- Aerodynamic Analysis and Optimisation of Wingtip-Mounted Pusher Propellers
- Experimental and numerical study onwingtip mounted propellers for lowaspect ratio UAV design
If you want to place solar panels on a wing, it is easier to have a rectangular wing. I think for this shape wing the wing tip losses as a glider would be more severe and so having wing tip propellers makes for a bigger win than normal shape wings.
