The Antares MA-32 is the first model in a large family of Ukrainian flying wing ultralight trikes that is designed and produced by Antares Aircraft and at one time marketed by Leading Edge Air Foils as the LEAF Antares. The aircraft are supplied as kits for amateur construction.
Design and development
The MA-32 is a two-seat design that was originally developed for European microlight competition flying. The aircraft has a standard empty weight of 321 lb (146 kg). It features a cable-braced hang glider-style high-wing, weight-shift controls, an open cockpit, tricycle landing gear and a single engine in pusher configuration.
The aircraft is made from bolted-together aluminum tubing, with titanium used on the carriage structure and wing attachment. The wing is covered in Dacron sailcloth. Its 33.8 ft (10.3 m) span wing is supported by a single tube-type kingpost and uses an "A" frame control bar. A number of single or double surface purpose-designed trike wings are optional, including the Aeros Still-17, Aeros Stream-16, Aeros Stranger 2, Aeros Profi, Aerossa Sprinter-15, Aerossa Stratos and the Aerossa Stratos-13. The landing gear uses a unique curved, slab-sided, main gear leg design made from fiberglass that reduces aerodynamic drag. All wheels have suspension and the steerable nose wheel also features a drum brake. A fiberglass cockpit fairing is optional. Series engines include the Rotax 447 two-stroke powerplant of 40 hp (30 kW), Rotax 503 of 50 hp (37 kW), the liquid-cooled Rotax 582 of 64 hp (48 kW), the Rotax 912 and 912S four-stroke powerplants of 80 hp (60 kW) and 100 hp (75 kW) and the HKS 700E of 60 hp (45 kW).
The aircraft can all be quickly folded for storage or ground transportation.
