LAK-17A

The LAK - 17A is a new generation of FAI 15m - 18m class sailplane designed and certified to the JAR - 22 category "U" specifications. It is a midwing glider with flaps, T - tail, retractable main landing gear with the shock absorber, pneumatic tail wheel and is capable of carrying 180ltr water ballast.

The sailplane is made of hybrid composite materials such as Kevlar, carbon, and glass fiber. The wing spar is made of modern carbon rods GRAPHLITE SM315 and has a double T section. The weight of each wing panel is about 55 kg. The airbrakes are situated in upper surfaces only. The wing airfoil is LAP 92 - 130/15 and it passes into the LAP 92 - 150/15 in the tip.

The cockpit is of monocoque construction. The manually contoured seat pan and an adjustable seat back together with optimally arranged control elements offer notable comfort on long flights. The one-piece Mecaplex canopy hinges forward. On the left side there is a sliding window with ventilation scoop. The instrument panel lifts up together with the canopy.

The retractable landing gear has a 350x15mm tire and shock absorber. The mechanical main wheel brake is actuated by a handle on the control stick. The rudder pedals are adjustable in flight. All controls, including the water ballast system, hook up automatically. The tow release is mounted near the main landing gear and permdits winch as well as aerotow take off. The wings incorporate fork - type spar roots joined with two pins.

The T-tail (fixed stabilizer with elevator) provides stable and responsive pitch characteristics. The elevator hooks up automatically during assembly. The glider is fitted with a fin ballast tank (capacity 7ltr) in order to compensate the nose-heavy moment created by the high ballast loads in the wings tanks. The fin ballast tank is jettisonable in flight. The water ballast is filled in, and emptied out through the holes at the bottom of the wings. The VHF antenna is mounted in the vertical fin.

Warranty 24 months or 200 flight hours whatever comes first.
