The LAK-12 is a Lithuanian mid-wing, single-seat, FAI Open Class glider that was designed and produced by LAK (Litovskaya Aviatsionnaya Konstruktsiya) (English: Lithuanian Aircraft Builders) and later by Sportine Aviacija and Sport Aviation USSR.[1][2]

Design and development

The LAK-12 was designed in the 1980s as an open class racer.[1]

The aircraft is made from fibreglass, foam and carbon fibre. Its 20.42 m (67.0 ft) span foam-core wing employs a Wortmann FX67-K-170 airfoil at the wing root, transitioning to a FX67- K-150 section at the wing tip. The wings feature both double-panel upper surface air brakes and flaps that can be set to -7°, -4°, 0°, +5°, +11° and +15°. Water ballast is 190 l (50 US gal) held in the wing leading edges and dumped through a centre-fuselage valve. The landing gear is a single retractable monowheel suspended by an oil/nitrogen oleo, plus a tailskid. The cockpit canopy is of one-piece and forward hinged.[1][3]

Operational history

In August 2011 there were 24 LAK-12s listed on the United States Federal Aviation Administration registry, all in the Experimental - Racing/Exhibition category and one registered with Transport Canada in the Limited Class.[2][4]
