sailplane of FAI standard class.
Sailplane description
Fuselage
The fuselage tapers behind the wing, the faired-in one piece
canopy is hinged forward.
The fuselage shell is of GRP single skin construction, therefore
capable of large energy absorption. The fuselage shell is supported
by GRP profile frames.
The pilot is seated in a semi-reclining position.
The landing gear is retractable.
A C.G. release is fitted as standard, and an Aerotow nose release
can be fitted on request.
Wing
The two-piece wing is cantilever and double trapezoidal. It is
constructed as a GRP-Foam-Sandwich shell with spar caps of
parallel glass fibers, extruded by a method developed by Hütter and
Hänle, and shear webs of reinforced GRP-Foam-Sandwich. The air
brakes are located only on the wing upper surface aprox. in one
third of wing semi-span. The ailerons have an internal drive thus
the wing skin is not disturbed.
The two replaceable water ballast bags can carry up to 115 liters
i.e. 25.3 Ukgal, 30.4 USgal.
Horizontal Tail Unit
The horizontal tail unit consists of a stabilizer and elevator.
Trimming is by means of a leaf spring on the control column,
adjustment is possible by a touch-button on the handgrip of the
control column. The stabilizer is of GRP-Foam-Sandwich
construction.
