Comment:
Th LAK-12 is a single-seat FAI Open-class mid-
wing sailplane with a one-piece forward-hinged
canopy. The retractable main wheel rides on an
oil/nitrogen shock absorber and uses a mechanical
brake. A skid is used at the tail. The wings
are glass-foam-glass construction and taper from
a Wortmann FX67-K-170 airfoil inboard to an FX67-
K-150 at the tips. Glidepath control is provided
by double-panel upper surface airbrakes and by
the flaps (-7, -4, 0, +5, +11, +15 deg). The
wings are capable of holding a total of 190
liters of water in their leading edges and are
filled and emptied through a hole in bottom of
the fuselage. |
