Nieuport-Delage NiD 39

The Nieuport-Delage NiD 39 was an airliner produced in France in the late 1920s, developed from the NiD 38. The airline Compagnie Aerienne Francaise, which had bought four examples of the earlier aircraft, ordered an improved version with greater passenger capacity. Like its predecessor it was a single-bay biplane of conventional design with an enclosed cabin for the passengers and an open cockpit for the pilot, but it carried four passengers where the NiD 38 carried two. The airline specified the Armstrong Siddeley Lynx engine, although the first eight examples flew with the Hispano-Suiza engine that had powered the NiD 38. The main production version, the NiD 391, had a Lynx IVC of 150 kilowatts, weighed 898 kilograms empty and reached 175 kilometres per hour. The airline operated around thirty examples on routes between western European cities until 1932.
