Webb22 maj 2024 · Propeller blades should have an airfoil shape, with the cross-section showing camber and twist, which will generate more lift than flat blades of the same area. A flat blade is not as efficient as a fully shaped blade, with camber, curve and twist. Why is Blade Area and BAR Important? Blade area and BAR (blade area ratio) is key to thrust. WebbMost propellers are made with three blades as a compromise for vibration, convenient size, efficiency, and cost. The efficiency difference between a two- and a three-bladed propeller is considered less significant than the vibrational difference.
