7.2 SAILPLANE DESCRIPTION
The L 23 SUPER BLANIK
-
sailplane is a cantilever, high-wing, two-seat glider
of all-metal structure. The rudder, elevator and ailerons are fabric covered. In
the forward section part of the fuselage there are front and rear cockpits. Both
cockpits are covered with a two-part canopy which can be jettisoned in flight.
Both cockpits are equipped with all sailplane flight control including flight and
navigation instrument panels. The sailplane is equipped with tow hooks either
for winch or aero-tow take-off.
Wings including ailerons and air brakes, are attached to the fuselage at six
suspension points (three on each side.There is a possibilityof using the wing
tip extensions which enlarge the wing span from the 81st series. They may be
connected to the standard wing instead of the laminated wing tips. The vertical
stabilizer is permanently fixed to the rear fuselage section. The horizontal
stabilizer is fastened by hinges on the top of the vertical stabilizer.
Elevator and aileron controls are actuated by control push rods and control
cables, the rudder control is pedal- operated also by control push rods and
control cables. Air brakes are controlled by control levers. The elevator trim
tab is controlled by the control lever.
The sailplane is equipped with the main landing gear and the tail landing
gear. The main landing gear is mechanically semi-retractable with an
oleo-pneumatic shock-absorber and a mechanical brake. The tail landing gear
is equipped with a wheel and shock-absorber . Cockpits are ventilated by cold
air tapped from the nose part of the fuselage. The baggage compartment is
behind the rear cockpit. Both cockpits are upholstered.
