The Flylight Dragonfly is a British ultralight trike, designed by Ben Ashman and produced by Flylight Airsports of Northamptonshire. The aircraft is supplied as a complete ready-to-fly-aircraft.[1]
Development of the Dragonfly started in 2007 with the aircraft entering series production in 2008.[2]
Design and development
The Dragonfly was designed to comply with the Fédération Aéronautique Internationale microlight category, the UK Single-Seat De-Regulation (SSDR) guidelines, as well as the US FAR 103 Ultralight Vehicles rules. It features a strut-braced Aeros Discus hang glider-style high-wing, weight-shift controls, a single-seat open cockpit, retractable 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 10.3 m (33.8 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a single cylinder, air-cooled four-stroke, 22 hp (16 kW) Bailey V4 200 engine, with the single cylinder, air-cooled, two-stroke 33 hp (25 kW) Simonini Mini-3 or 33 hp (25 kW) Simonini Mini-2 engines optional.[1]
With the Bailey engine and the Aeros Discus 15T wing the Dragonfly has an empty weight of 80 kg (176 lb) and a full fuel capacity of 20 litres (4.4 imp gal; 5.3 US gal). With its manual, or optionally electrically retractable landing gear the aircraft can be folded up and ground transported in the trunk of a car.[1]
A number of different wings can be fitted to the basic carriage, including Aeros Discus 15T, 14 and 12 as well as the Aeros Combat 12T.[1]
