Nieuport-Delage NiD 37

The Nieuport-Delage NiD 37 was a single-engine, single-seat monoplane fighter and racing aircraft designed and built in France in the early 1920s, with a small foreplane to bring the centre of pressure forward. It was built around four spars, covered in stressed three-ply and fitted with long-span ailerons, and was powered by an upright water-cooled Hispano-Suiza 8Fb V-8 engine of 220 kilowatts. The aircraft first appeared in public at the Paris Air Show in December 1922 without having flown, and made its first flight the following April. It proved heavy and slower than expected, and had turbo-supercharger problems, so development ended without any aircraft entering service. A second aircraft was built as a racer with a much smaller wing area and a cantilevered upper wing, but after a carburettor fire in the 1922 Coupe Deutsch it withdrew and was retired for good.
