This new open class two-seater self-sustaining
sailplane is designed to meet the latest standards of the gliding industry.
Glider is of normal aerodynamic configuration with "T" tail and wings
slightly swept forward.
Due to changeable wingtips, glider can have 23m or 26m wingspan with
winglets.
Latest achievements in engineering and aerodynamics allowed to design
wing with very high aspect ratio, which made
possible to improve glider performance to the new levels.
Glider is made of modern composite materials using
already known LAK brand technologies such as use of pultruded
carbon rods for the wing spar construction and others.
Glider construction allows installation of the power plant.
-Self-sustaining (LAK-20T) versions so called "turbo" is
powered with SOLO 2350C engine (reduction gearing 1:1,56)
-Self-launching
(LAK-20M) version is planned with powerful SOLO 2625 02 engine.
