Design and development
[edit]The Royal 912 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 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 single surface wing covered in Dacron sailcloth. Its 10.48 m (34.4 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912 or 100 hp (75 kW) Rotax 912S engine. The aircraft has an empty weight of 230 kg (507 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 220 kg (485 lb). With full fuel of 55 litres (12 imp gal; 15 US gal) the payload is 180 kg (397 lb).[1]
The aircraft carriage is manufactured under sub-contract in Slovenia. A number of different wings can be fitted to the basic carriage, but the standard wing is the Drachen Studio Kecur EOS 15 with a wing area of 15 m2 (160 sq ft) and which is equipped with spoilers.[1]
