5-Cylinder Radial Engine in detail
The story
With its cylinders arranged in a star around the crankshaft, the radial engine powered a large share of aircraft from the 1920s to the 1950s, from mail planes to airliners. Cooled by the air striking it head-on, with no radiator and no coolant, it offered great power for little weight.
What you'll see move
Turn the crankshaft: the five pistons rise and fall in turn in their cylinders, the connecting rods converge on the centre and the valves open at the right moment. The whole cycle of an aero engine can be followed from the front.
