Just curious, and this might sound naive but this is a serious question.
Are drone "blades" (not sure of the correct term) more efficient when they aren't enclosed? I understand this is a test unit and there are myriad safety precautions taken when testing. But my first thought when seeing open blades is what happens if it falls, trips or otherwise goes out of control? Then you have rapidly spinning blades going helter skelter to deal with. Not just hitting into any soft humans standing around. But the floor, tables, doors, wires, expensive computer equipment. It seems a bit daft unless it has a purpose that I've missed.
- SamBam 5y agoMost drone propellors are extremely lightweight, meaning that the damage they can inflict is very limited.
- glitchcrab 5y agoThey have very high RPM though as my finger can attest when I mis-judged catching my DJI done once - the cut was surprisingly deep for light plastic props. I'd hate to see what a more substantial prop could do.
- fh973 5y agoGenerally, ducted propellers are more efficient. And yes, these blades are effectively rotating knives. Even small drone motors and propellers are very dangerous as the motors have a lot of power and high RPM, and the more high-end ones are made of CFK and have sharp edges. As these four do not only lift a drone, but a whole robot frame, I'd assume they'd easily cut through a finger.
