Distar UFM-13 Lambada

From Wikipedia, the free encyclopedia

The Distar UFM-13 Lambada (named for the Brazilian dance) is a Czech shoulder-wing, two-seat motor glider originally designed and produced by Urban Air and now built by Distar Air of Ústí nad Orlicí.[1]

Design and development

The Lambada was designed to comply with the Fédération Aéronautique Internationale microlight rules at a gross weight of 472.5 kg (1,042 lb) and US light-sport aircraft rules at 600 kg (1,323 lb). The design is on the Federal Aviation Administration's list of approved special light-sport aircraft.[1][2][3][4]

The aircraft features a cantilever wing, a T-tail, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear or conventional landing gear with a steerable tail wheel and a single engine in tractor configuration.[1][4]

The aircraft is made from composites. Its 13 m (42.7 ft) span wing employs a SM 701 airfoil, has an area of 12.16 m2 (130.9 sq ft) and flaperons with spoilers or optionally ailerons and dive brakes. Flaperon settings are 0°, 5°, 9° and 16°, with the last setting assisted by the spoilers. The wings can be extended to 15 m (49.2 ft) with wing tips for soaring. The main landing gear legs are fabricated from fibreglass laminates and the wheels are equipped with single lever hydraulic brakes. Standard engines available are the 80 hp (60 kW) Rotax 912UL and the 85 hp (63 kW) Jabiru 2200 four-stroke powerplants.[1][4][5][6]

The aircraft achieves a 26:1 glide ratio with 13 m wings and 30:1 with 15 m wings fitted. Aside from its use as a motorglider, the Lambada has also been successfully employed as a glider tug.[1]
