Propeller Blades: The Key to Efficiency Improvements

Propeller design is all about tradeoffs. The designer tries to create the most efficient propeller possible. The principle challenge to this is the direction of water velocity. Then the tradeoffs of propeller blade design are complex, with many choices along the way. To go from ideal to practical propellers, we need to understand the choices and tradeoffs.
