The Fouga CM.88 Gemeaux was a 1950s French engine test-bed aircraft produced by Fouga. An unusual aircraft, 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 Gemeaux I and first flew 6 March 1951, it was fitted with two Turbomeca Piméné turbojets, one on top of each fuselage. Further variants were produced as the engine fit was changed.

Variants

Gemeaux I
Original configuration with two 220 lb (100 kg) Turbomeca Piméné turbojet engines, first flown 6 March 1951.
Gemeaux II
Designation when powered by one 606 lb (275 kg) Turbomeca Marboré I turbojet engine, first flown 16 June 1951.

An unpowered sub-scale N-20.01 glider and a turbojet powered test aircraft, also sub-scale and known as the N-20.02 Arbalète ("Crossbow"), were test flown. A fighter prototype N-20.10 Aiguillon was built but never flown, and a twin-engines N.20.20 Harpon was also proposed but not followed up.

In response, the firm designed the mixed-propulsion Trident, powered by a single SEPR rocket engine, which was augmented by wingtip-mounted turbojet engines, and the Air Force ordered two prototypes.
