The action of a propeller is that of a rotating wing where the lift provided by the wing is the desired thrust for propulsion. The blades also have an associated drag which reduces the overall ...

Fly without wings or propellers? One team just made it happen—this breakthrough could forever change how we take to the skies.

That’s not really what you want if you’re testing brushless motors and prop configurations, anyway; similarly sized props can have very different thrust profiles. Instead of building a dyno ...
