WebThe 3-blade propeller will generally have a smaller diameter than the 2-blade propeller that it replaces, which also reduces the tip speed and noise. In a twin-engine aircraft, the reduced diameter of the 3- blade propeller will result in less tip-generated noise and a greater clearance between the blade tip and the fuselage. gilgamesh civ6 mod
