The engines used to provide thrust may be of several types. Often an internal-combustion piston engine is used, especially for smaller planes. They are of various types, based on the arrangement of the cylinders. Horizontally opposed engines employ four to six cylinders lying flat and arrayed two or three on each side. In a radial engine the cylinders (ranging from 5 to as many as 28, depending on engine size) are mounted in a circle around the crankshaft, sometimes in banks of two or more…

A small ion engine uses high voltage to accelerate ions, which are then expelled out of the engine to create thrust. This is a type of electric propulsion system that is highly efficient and can be used for long-duration space missions. As the ions are expelled, the engine rotates due to the resulting thrust, which can be used for propulsion or attitude control.
