The Schönleber Vento (transl. Wind) is a German ultralight trike designed and produced by Schönleber Metallbau GbR of Schönaich and formerly located in Regensburg. The aircraft is supplied complete and ready-to-fly.[1]

Design and development

The company has been producing ultralight trikes since the 1990s, mostly to supply local customers and without advertising. The company's main business is metal fabrication.[1]

The Vento was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 400 kg (882 lb).[1]

The aircraft design features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with an optional cockpit fairing, tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 9.5 m (31.2 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine, equipped with a 4:1 belt reduction drive to reduce the aircraft's noise signature.[1]

The aircraft has an empty weight of 160 kg (353 lb) and a gross weight of 400 kg (882 lb), giving a useful load of 240 kg (529 lb). With full fuel of 60 litres (13 imp gal; 16 US gal) the payload is 197 kg (434 lb).[1]

A number of different wings can be fitted to the basic carriage, including a special wing for hang glider towing.[1]
