Other forms: propellers
A propeller is the spinning blades that pull an aircraft along. A four-blade propeller, the propeller stopped, propeller wash.
Each blade is a small wing, and the twist along its length exists because the tip travels much faster than the root, so both parts have to meet the air at a workable angle. A ship's propeller works the same way in water.
