The Weller ULI NG (New Generation), sometimes called the Weller Uli NG, is a German ultralight aircraft, designed and produced by Weller Flugzeugbau of Bibersfeld. It was introduced at the Aero show held in Friedrichshafen in 2010. The aircraft is supplied as a complete ready-to-fly-aircraft.[1][2]
The aircraft is derived from the Egon Scheibe Uli 1 and was re-designed to comply with the German 120 kg (265 lb) class ultralight rules. It features a cable-braced high-wing, a single-seat open cockpit without a windshield, fixed conventional landing gear and a single engine in pusher configuration.[1][2][3]
The aircraft fuselage is made from welded steel tubing, the wing built from bolted-together aluminum tubing, with its flying surfaces covered in aircraft fabric. Its 9.68 m (31.8 ft) span wing has an area of 12.78 m2 (137.6 sq ft), giving a very light wing loading of 17.0 kg/m2 (3.5 lb/sq ft). The standard engine available is the 30 hp (22 kW) Briggs & Stratton industrial four-stroke powerplant with a V-belt reduction drive, powering a two bladed wooden propeller. The engine burns 5 litres (1.1 imp gal; 1.3 US gal) per hour at cruise. The aircraft's 18 litres (4.0 imp gal; 4.8 US gal) fuel tank is detachable for refueling and is filled with premium auto-fuel. The design incorporates a ballistic parachute whole-aircraft rescue system that includes an ignition cut-off upon firing.[1][2][3]
