Propeller Airplane

A propeller as a spinning wing that produces lift, but in a forward direction—better known as thrust. A difference in air pressure between the front and back surfaces of its blades while it is moving causes lift.  Propeller airplanes need help from an engine.  Here is a great article all about propeller planes from the Smithsonian Air and Space Museum.
