Nieuport-Delage NiD 640


The Nieuport-Delage NiD 640 was a French four-passenger transport monoplane built by Nieuport-Delage.

Development

The NiD 640 was an all-wood high-wing cantilever monoplane powered by a nose-mounted radial engine. An enclosed cockpit for two-crew forward of the wing and a cabin for four passengers was aft. The NiD 640 was powered by Wright J-5C radial engine and was followed by 12 production aircraft designated NiD 641 powered by a Lorraine 7M Mizar radial engine. The NiD 640 was converted to an ambulance aircraft and later had a Mizar engine fitted to bring it up to 641 standard. One aircraft was powered by a Armstrong Siddeley Lynx Major engine and designated the NiD 642 but it did not find a buyer and was scrapped. Seven NiD 641 aircraft were flown by Société des Transports Aériens Rapides, a subsidiary of Nieport-Delage, on cargo and passenger services from Paris.
