Nieuport-Delage NiD 640
|Role||four-seat cabin monoplane|
|Primary user||Société des Transports Aériens Rapides|
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 160 kW (220 hp) Wright J-5C radial engine and was followed by 12 production aircraft designated NiD 641 powered by a 180 kW (240 hp) 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 175 kW (235 hp) 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 (STAR), a subsidiary of Nieport-Delage, on cargo and passenger services from Paris.
