of which a single prototype was built. Soon afterwards, Nieuport-Delage built two examples of a modified version for the 1924 Coupe Beaumont as the NiD 42S,''The Illustrated Encyclopedia of Aircraft'' 1985, p. 2600. on which the main wings were mounted directly to the sides of the upper fuselage at shoulder position with a short subsidiary wing fitted around the undercarriage axle. To further streamline the design, the surface radiators were installed on the upper surface of the wing."The Nieuport-Delage Type 42", p. 461.

Operational history

One of these aircraft was flown by

Joseph Sadi-Lecointe Joseph Sadi-Lecointe (1891 – 1944) was a French aviator, best known for breaking a number of speed and altitude records in the 1920s. Biography Sadi-Lecointe was born on 11 July 1891 at Saint-Germain-sur-Bresle. He learned to fly at the Ze ...

'' Flight,'' 26 June 1924, p. 416. Retrieved: 16 September 2012. Indeed, having finished the prescribed six laps of the course, Sadi-Lecointe flew another four laps to break the world speed record over a 500-km closed-course. His average speed in winning the Coupe Beaumont was and over the was , beating the previous record for the latter by . On 15 February the following year, Sadi Lecointe took a NiD 42S up to a speed of and went on to win the 1925 Coupe Beaumont with a NiD 42S on 18 October with an average speed of ."Sadi Lecointi wins Beaumont Cup."
'' Flight,'' 22 October 1925, p. 682. Retrieved: 16 September 2012. While the NiD 42S was achieving these distinctions, development continued on the fighter version. Nieuport-Delage designed two further such variants in 1924; a single-seater designated NiD 42 C.1 and a similar machine with a second cockpit for a tail gunner with a machine gun in a ring mount, designated the NiD 42 C.2. One of the latter was exhibited at that year's ''

'', along with a NiD 42 C.1 nose section to illustrate an alternative engine mount."The Paris Aero Show 1924" 1924, p. 774. These differed from the original NiD 42 fighter in having a second, small wing added to the lower fuselage, turning the parasol monoplane into a sesquiplane, a design feature adopted from the NiD 37Hartmann 2006, p. 15. which would be a key identifying feature through most of the versions developed from the 42. Only two examples of the two-seater were built, but Nieuport-Delage entered the single-seater in the 1925 ''concours des monoplaces'', a competition by the Army's Technical Service to find a replacement for the NiD 29. The NiD 42 was selected from a field of eleven competitors, and an order for 50 aircraft was placed, of which 25 were eventually delivered. Although impressive at the time it was designed, technology had already surpassed the NiD 42 when it entered service in 1928, particularly with regard to its wooden structure, and most of the development work associated with the design was made in an effort to cure it of a tendency to enter a flat spin. Nevertheless, it provided the foundation for further development as the NiD 52 and NiD 62.Taylor and Alexander 1969, p. 117.
