How a Propeller Plane works

Propeller planes are aircraft powered by one or more propellers, rotating airfoils that generate thrust by accelerating air backward. They may use piston engines, turboprop engines, or, in some experimental designs, electric motors. Propeller aircraft were the dominant form of powered flight from the early 20th century to the mid-century, before jet engines became standard for application in various high-speed aviation scenarios. Propeller planes remain widely used because they are efficient at low to medium speeds and on shorter routes. Small general-aviation aircraft, cargo planes, agricultural aircraft, training aircraft, bush planes, and many regional airliners still use propellers. Their relatively low operating costs and manageable speeds also make them common in flight schools. Compared with jet aircraft, propeller planes usually fly slower and at lower altitudes, but they can operate from shorter or rougher runways and often cost less to run. Their characteristic sound comes from the propeller blades cutting through the air, a familiar mechanical signature of aviation’s earlier age that remains in everyday use.
