The Göppingen Gö 9 was a German experimental aircraft built to investigate the practicalities of powering a plane using a pusher propeller located far from the engine and turned by a long driveshaft.

In 1937, Claudius Dornier observed that adding extra engines and propellers to an aircraft in an attempt to increase speed would also attract a penalty of greater drag, especially when placing two or more engines within nacelles mounted on the wings.

The aircraft was designed by Dr Ulrich Hütter as a 40% sized, scaled-down version of the Dornier Do 17's fuselage and wing panels without the twin-engine nacelles, and built by Schempp-Hirth.

Power was supplied by a Hirth HM 60 inverted, air-cooled inline four-cylinder engine mounted within the fuselage near the wings.

Other than the engine installation, the only other unusual feature of the aircraft was its all-new, full four-surface cruciform tail, which included a large ventral fin/rudder unit of equal area to the dorsal surface.
