Airplane Engines

An airplane engine provides propulsion to the airplane. It drives the propeller which provides thrust on the same principle as the airplane wing provides lift. World War II engines were reciprocating, internal combustion engines. Most were air-cooled rather than liquid-cooled to save weight. The two basic engine designs were (1) in-line in which the cylinders were in one row or two parallel rows in a V-shape, or (2) radial in which the cylinders are arranged in a circle, which gave more air access for cooling. ^Wiki The in-line engines were less powerful than the radial engines. Both used 100-octane gasoline for maximum power.
