The ATEC 122 Zephyr 2000 is a Czech ultralight aircraft, designed by Oldrich Olansky and produced by ATEC v.o.s. of Libice nad Cidlinou. The aircraft is supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction. [2] [3] [4] [5]
The Zephyr was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear, a T-tail and a single engine in tractor configuration. [2] [3] [4]
The aircraft's fuselage is made from composites with wooden bulkheads. The semi-tapered 9.6 m (31.5 ft) span wing is made from plywood with composite spars and leading edges and employs a UA-2 airfoil. The wing is covered with doped aircraft fabric. The standard engine factory-supplied was the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant. [2] [3] [4] [5]
The Zephyr is noted for its low payload. With a useful load of 197.5 kg (435 lb) and full fuel of 43 kg (95 lb), this leaves only 154.3 kg (340 lb) for occupants and baggage. [2] [3] [4]
The Zephyr was later developed into the ATEC 321 Faeta. [2]
