Nieuport-IX

23k b/w "History of aircraft construction in the USSR", Vol.1 p.300

First of large family of 'Nieuport' biplane fighters/scouts (IX to XXV). General layout and design changed only slightly, some were built as two-seaters. All were powered by rotary engines (Rhone or Clerget, from 80 to 130hp). Wooden wire-braced fuselage and wings were covered with fabric, only very front (close to the engine) was aluminum, as well as the engine cowling.

Aircraft had unusual wing configuration. Slightly-swept upper wing (3°) with a cut-out for cockpit access carried ailerons (widened to the outboard end). Lower wing was of high aspect ratio and had 2° dihedral. Wings vere linked by wide hollow wooden V-strut. Tailplane and rudder were flat.

Nieuport-IX was a two-seater. Observer occupied front cockpit. He could fire a rifle above the propeller arch after climbing on his seat and through a hole in the upper wing. No machinegun was provided.
