The Teratorn T/A is an American ultralight aircraft that was designed and produced by Teratorn Aircraft. The aircraft was supplied as a kit for amateur construction.[1]
Design and development
The first design by Teratorn Aircraft was known simply as the Teratorn, named after the extinct ice-age soaring bird. The company took its name from the first design. This design quickly evolved into the T/A model and was produced until supplanted in production by the Tierra I.[1]
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The original Teratorn has a standard empty weight of 212 lb (96 kg). It features a cable-braced high-wing, a single-seat, open cockpit, conventional landing gear and a single engine in pusher configuration.[1]
Both the Teratorn and the T/A are made from bolted-together aluminum tubing, with the flying surfaces covered in Dacron sailcloth. Its single-surface 32 ft (9.8 m) span wing is supported by cables attached to a simple kingpost. The landing gear is bungee suspended. Both models were supplied with the 28 hp (21 kW) Rotax 277 single cylinder, two-stroke powerplant as their standard engine.[1]
The T/A model proved a commercial success and a large number were sold. The Skye Treck Skyseeker was based on the T/A.[1]
