The Ekolot KR-030 Topaz is a Polish ultralight aircraft, designed and produced by Ekolot of Krosno. It was certified in Poland in February 2010. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly aircraft.[1][2]
Design and development
[edit]The Topaz is a development of the Ekolot JK-05L Junior and was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever high wing in place of the Junior's strut-braced wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1][2]
Like the Junior, the Topaz is made from composites. Its 10.76 m (35.3 ft) span wing employs an NN-1817 airfoil, has an area of 10.24 m2 (110.2 sq ft) and flaps. Dual 35 litres (7.7 imp gal; 9.2 US gal) fuel tanks are located behind the seats. A ballistic parachute is an available option. The standard engine available is the 80 hp (60 kW) Rotax 912UL four-stroke powerplant.[1][2][3]
The use of a one-piece wing without struts gives the Topaz a 20 km/h (12.4 mph) higher cruise speed than the Junior, while resulting in the same empty weight.[1][2]
The Topaz has been accepted by the US Federal Aviation Administration as a light-sport aircraft.[4]
