The Sunward ST is a Chinese ultralight trike designed and produced by Sunward Tech (Hunan Sunward Science & Technologies Company Limited) of Zhuzhou. The aircraft is supplied complete and ready-to-fly.^[1]

Design and development

The ST was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}. The aircraft has a maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}.^[1]

The aircraft design features a strut-braced topless hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.^[1]

The aircraft is made from bolted-together aluminum tubing and composites. It uses a double surface Grif Hazard wing, made by the Italian company Grif Italia. The {{convert|10.38|m|ft|1|abbr=on}} span wing is supported by struts and uses an "A" frame weight-shift control bar. The powerplant is an Austrian-made twin cylinder, liquid-cooled, two-stroke, dual-ignition {{convert|64|hp|kW|0|abbr=on}} Rotax 582 engine or four cylinder, air and liquid-cooled, four-stroke, dual-ignition {{convert|80|hp|kW|0|abbr=on}} Rotax 912UL engine.^[1]

The Rotax 582-equipped model has an empty weight of {{convert|198|kg|lb|0|abbr=on}} and a gross weight of {{convert|450|kg|lb|0|abbr=on}}, giving a useful load of {{convert|252|kg|lb|0|abbr=on}}. With full fuel of {{convert|60|l}} the payload is {{convert|209|kg|lb|0|abbr=on}}.^[1]

Variants

ST582

Model powered by a Rotax 582 two-stroke powerplant. Designed for flight training and aerial work, an agricultural aircraft version was introduced in 2012 with crop-spraying gear. This includes a {{convert|120|kg|lb|0|abbr=on}}-capacity tank that can cover {{convert|13.34|sqkm|sqmi|0|abbr=on}}.^[1]

ST912

Model powered by a Rotax 912UL four-stroke powerplant.^[1]
