My father’s Cessna 182 had a 2-bladed prop. I can remember many Beechcraft had 3-bladed props., a DC-6 had 4-bladed props, and recently, a E-2 Hawkeye has an 8-bladed prop. What’s the advantage to more blades? I would think the engine’s power would be converted to motion regardless of the blade count.
The only things I can think of are:
=== ground clearance; more blades = shorter blades
=== lighter blades; with more blades, each blades needs to support less, but the mass of 8 blades would outweigh the strenghening of four blades.
And as a side note: does/did anyone make a 5, 6, or other blades prop?
