Oh sure, but the glider is moving through the air at a stately pace (generally between 50-95mph), shedding vortices without anything coming behind them to crash into them. A prop operates at much higher speeds, typically between 450-720mph!
- mikeash 8y agoReally? I arbitrarily looked up the DJI Phantom 3 and found a max RPM of about 8000 with a prop diameter of 9 inches, which gives a tip speed of about 200 MPH at the most. That’s still pretty fast, of course. That points to using bigger props as a potential way to cut noise.
- toufiqbarhamov 8y agoYou’re right, I was looking at max motor rpm, whoops!
