Moynet Jupiter

The Moynet M 360 Jupiter was a small executive transport built in France in the 1960s. It had an unusual twin-push-pull, single-fuselage configuration. Two prototypes were produced, the second with more power and seating, but no sales resulted.

Design and development

Some civil propeller driven aircraft that have used one or more pairs of engines in push-pull configuration have been flying boats, with engines mounted above the wing and clear of spray. Others have had a pair of engines, one at either end of a pod fuselage with a tail unit mounted on a pair of booms, for example the Cessna Skymaster, the Adam A500 or the Rutan Voyager. The Moynet 360 Jupiter was an example of a push-pull aircraft of a less common configuration, where a single conventional fuselage has an engine at either end; the Dornier Do 335 fighter used the same arrangement. For light civil aircraft, the aim was to combine the performance of a conventional twin-engined aircraft with the ease of handling of a single-engined one.

The Jupiter was an executive transport with between four and seven seats, depending on engine power. It was designed by André Moynet, a member of the National Assembly of France and a former government minister, while also a test-pilot, and built by S.S. Engins Matra (so it is sometimes referred to as the Matra Moynet Jupiter), the first prototype flying on 17 December 1963 with the designer and Lucien Tieles at the controls. Its wing had a straight trailing edge, but the centre section had strong taper on the leading edge which continued more weakly outboard.
