The N1 Sala was a single seat competition, 18 m (59 ft 1 in) span glider built in Italy in 1937. Only one was constructed.
Development
The 1937 N1 Sala was designed by Guglielmo Negri and built by Fratelli Sala, whose main occupation was the production of wooden propellers for the military. It was a high wing monoplane with its two spar wing supported centrally on a fuselage pedestal and braced on each side with a pair of parallel wooden faired [[strut] from the spars at about 20% span to the lower fuselage. The wing, mounted withoutdihedral, had a rectangular centre section out to about quarter span and long, strongly straight tapered, round tipped outer panels which [[trailing edges almost entire filled by the ailerons. The high aspect ratio (21:1) wing was completely fabric covered.[1]
The Sala had a plywood covered, ovoid section fuselage with an open cockpit immediately ahead of the wing pedestal. The cockpit lacked a windscreen but was well instrumented for a glider of the day, with air speed indicator, altimeter, turn and bank indicator and variometer. The fuselage tapered rearwards to the tail where the tailplane, with a straight, swept leading edge and carrying elliptically shaped, aerodynamically balanced elevators, was mounted on top. The fin was no more than a mounting for the tall, curved edge, balanced rudder, which extended down to the keel and moved in an elevator cut-out. The standard glider rubber sprung ash skid, running from just aft of the nose to below the wing trailing edge served as an undercarriage, assisted by a very small tail skid.[1]
