An interesting safety feature found on turboprops is called Propeller Feathering. What is it, and how does it work?

Later came variable-pitch propellers, where the angle of attack of the blades could be increased collectively to take a bigger “bite” of the air for more thrust.

The propeller company advised Lindbergh that a pitch setting of 15.5 degrees would be best for takeoff, but 16.5 degrees would give the best efficiency in cruise. Lindbergh opted for cruise.

While both elements are essential to performance, the pitch comes first when shopping. Thankfully, understanding propeller pitch is simple. The pitch of a propeller is the number of inches it moves ...

A variable-pitch propeller allows your boat to shift gears like a car, since it's designed to maintain a low pitch angle during initial acceleration, then shift to a higher pitch angle in the ...

The display mode enables graphing of any radial distribution, such as chord, skew or pitch angle. One-click graphing allows quick visualization of blade outlines, thickness profiles, and 2D ...
