You're not countering gravity, you're countering the mass of the helicopter vs. the mass of the air moved. Thus, since the air is thinner: to push larger blades

You're not countering gravity, you're countering the mass of the helicopter vs. the mass of the air moved. Thus, since the air is thinner: to push larger blades going at the same speed, OR the same sized blades going at a faster speed, you'd need more power.
- nickff 3y agoI don’t think you can spin the blades much faster, as Earth-bound helicopters already have issues with blade tip speeds approaching the speed of sound. Short blades are less efficient anyway, and I’m not sure why pushing larger blades will require more power; that would have to do with the balance between density of atmosphere and its viscosity.
