Airfoil: Shaped surface, such as an airplane wing, tail, or propeller blade, that produces lift and drag when moved through the air.
The two-section propeller is supported by a center bearing and coupled together by universal joints.
The propeller will windmill and crank the engine.
The reason the propeller shaft shortens as the angle increases is that the rear axle and differential move in a shorter ARC than the propeller shaft.
The boat's engine stopped Because the propeller had fallen foul of some weed
This accommodates any effective change of length of the propeller shaft as the rear axles move toward or away from the CAR frame.
Deicer:a device used on an aircraft to keep the wings and propeller free from ice or to remove ice after it has formed.
By its rotation In water or air, the propeller produces thrust on the blades, which gives forward motion to the vehicle.
A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, LIFT, thrust, or propulsion
Among commonly used types are those employing either a propeller or cups for measuring wind speed and a Vane for measuring wind direction
