The Avio Design Swan is a family of Bulgarian ultralight trikes, designed and produced by Avio Design of Kazanlak. The aircraft are all supplied as a complete ready-to-fly-aircraft.[1]
Design and development[edit]
The aircraft family was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). All models feature a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear with wheel pants 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. Typical wings used have a 9.5 to 10.2 m (31.2 to 33.5 ft) span wing, are supported by a single tube-type kingpost and use an "A" frame weight-shift control bar. The standard powerplant is the twin cylinder, air-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine. Options do not include the 80 hp (60 kW) Rotax 912 engine.[1]
