Aircraft Propellers: How They Work, How They Control RPM, and Why Blade Angle Matters
How They Work, How They Control RPM, and Why Blade Angle Matters Propellers look simple from the outside. A few blades spin around a hub and pull an airplane through the air. But once you start studying aircraft maintenance, you quickly discover that a propeller is actually a sophisticated aerodynamic system. On many aircraft, it is also part of a hydraulic and mechanical control system capable of automatically changing blade angle, maintaining engine RPM, feathering after an engine failure, and even producing reverse thrust after landing. ...
