Using a four-stroke cycle, this aircraft engine converts reciprocating (piston) action into rotary (crankshaft) motion. The rotating crankshaft turns a propeller, which creates thrust and causes the aircraft to move forward.
This particular engine powered a 1940s-era Globe Swift GC-1B, a light general aviation aircraft. While aircraft piston engine technology has improved greatly over time, the basic operating principles have remained the same.
