Fouga CM.88 Gemeaux
The Fouga CM.88 Gemeaux was a 1950s French engine test-bed aircraft produced by Fouga. An unusual aircraft as it was two aircraft joined by a common wing.
Design and development
To meet a requirement to use as an engined testbed for Turbomeca turbojets, Fouga combined two CM.8 fuselages. It used the port and starboard outerwings with a new wing centre section to join the two fuselages. The V-tails fitted to each fuselage were joined at the top in a W configuration. The type was designated the Fouga CM.88-R Gemeuax I and first flew 6 March 1951, it was fitted with two Turbomeca Piméné turbojet, one on top of each fuselage. Further variants were produced as the engine fit was changed.
