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.
