Why three blades
Blade count is a trade-off. Two blades are the most efficient in clean air but produce noticeable vibration. Four or more are smoother and quieter but each blade works in the disturbed wake of the one ahead, costing efficiency.
Three is the usual compromise, and it also happens to look right — a three-blade propeller is rotationally balanced and reads clearly as a shape from any angle, which two blades do not.
Marine propellers face the same maths plus cavitation: spin a blade fast enough and the water pressure on its back face drops low enough to boil at ambient temperature, forming bubbles that collapse and eat the metal.
