The air touching the blades isn’t moving. Kinda hard to conceive but YouTube wind tunnel testing with cars, they use smoke to test the aerodynamics. If you watch closely the smoke never actually touches the car, but moves ever so slightly above it. That small cushion of air is how it’s able to stay and stick
