Design and development

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category and the US light-sport aircraft category. It features a cable-braced or strut-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 Delta Jet is accepted in the United States as both an Experimental and Special Light-sport aircraft.[2][3]

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. The aircraft uses an "A" frame weight-shift control bar. The powerplant options include the twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine, the four cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912 or 100 hp (75 kW) Rotax 912S engine. In its AS-III model the aircraft has an empty weight of 236 kg (520 lb) and a gross weight of 472.5 kg (1,042 lb), giving a useful load of 236.5 kg (521 lb). With full fuel of 55 litres (12 imp gal; 15 US gal) the payload is 196.5 kg (433 lb).[1]

A number of different wings can be fitted to the basic carriage, including the cable-braced Aeros Profi, the strut-braced Aeros Profi TL and the Apollo Reflex 11 or 13.[1]
