Design and development

The Junkers Trike was originally designed as a single seater or "tight" two-seater, but later stretched to provide comfortable accommodation for two occupants.[1]

The aircraft 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 450 kg (992 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat or two-seats-in-tandem open cockpit with an aerodynamically streamlined cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.[1]

The aircraft fuselage is made from fibre glass, with its single or double surface wing covered in Dacron sailcloth. The typical wing used is of 9.6 m (31.5 ft) span, is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The standard powerplant factory supplied was the twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine.[1]

With the Rotax 582 the aircraft has an empty weight of 186 kg (410 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 264 kg (582 lb). With full fuel of 43 litres (9.5 imp gal; 11 US gal) the payload is 233 kg (514 lb).[1]

A number of different wings can be fitted to the basic carriage, including those made by Bautek and La Mouette. The aircraft was certified in Germany to DULV standards.[1]
