The Nieuport 31 monoplane fighter was the final Nieuport wartime design. Powered by a 170 hp Le Rhone rotary, it was planned to carry the typical two synchronized guns.The wheels were covered by a large auxiliary airfoil. No further development was undertaken, perhaps due to the success of the more conventional Nieuport 29 biplane and the declining interest in rotary engines.

The Nie 31, technically a sesquiplane, entered flight test during 1919.

The Nieuport 31 looked more like a racing aircraft than a fighter. As far as is known the aircraft was never fitted with armament. The streamline fairing that enclosed the landing gear was in the form of a sub-wing.

Nieuport 31
The Nieuport 31 was the last of the wartime Nieuport designs. It had a shoulder-mounted wing with a monocoque fuselage. The undercarriage was suspended beneath the fuselage by prominent struts and the wheels were partially covered by a large airfoil that actually served as a second wing. This auxiliary airfoil made the aircraft, for all practical purposes, a sesquiplane. The engine was a 170-hp Le Rhone 9R. The pilot sat behind and above the main wing, where he had a good field of view at least in part due to the large cut-outs in the trailing edge of the wing. Two pairs of large struts connected the main wing with the auxiliary wing/undercarriage. The fin and rudder assembly, as well as the monocoque fuselage, was similar to the Nieuport 29 series. Armament was intended to be two Vickers 7.7-mm machine guns. This airplane was not developed further, possibly due to the fact that the rotary engine had fallen into disfavor with the Aviation Militaire. It is also possible that the success of the more conventional Nieuport 29 obviated the need for the Nieuport 31.
