Three blades or four, how propeller design balances speed, power, and cavitation
Ship propellers are a constant compromise between efficiency, vibration, cavitation, and power delivery. This video explains why adding blades can solve serious mechanical problems, and why engineers ...
Could the secret to transforming propeller design lie in the dimples of a golf ball? It might sound far-fetched, but the same aerodynamic principles that allow a golf ball to soar farther and faster ...
