The Heinkel HE 18 was a sports aircraft built in Germany in the mid 1920s. It was a two-seat conventional low-wing monoplane. A development of the HE 3 it had a narrower fuselage than the HE3 having tandem seating instead of side-by-side. Also its wings were braced by a pair of struts on each side arranged in a V-shape with a single attachment point on each side of the upper fuselage where the HE 3 had cantilever wings.
