1.4 Descriptive data

The “Ventus-2c” is a flap equipped, single-seat high performance sailplane,

constructed from fiber reinforced plastic (FRP), featuring a T-tail (fixed horiz.

stabilizer with elevator, fin and rudder).

It can be flown in 15 m or 18 m configuration.

Wing

The four-piece (15 or 18 m) wing with winglets is multi-stage trapezoid in

planform with double-panel “Schempp-Hirth” type airbrakes on the upper

surface. The flaps act as full-span ailerons.

The water ballast tanks are integral compartments in the fwd. section of the

inbd. panels (174 Liter [45.97 US Gal., 38.28 IMP Gal.]) and in the 18m-outbd.

panels (28 Liter [7.40 US Gal., 6.16 IMP Gal.]).

Their total capacity is approx. 202 Liter (53.40 US Gal., 44.40 IMP Gal.).

The wing shells are a CFRP/foam-sandwich construction with spar flanges of

carbon fiber rovings and shear webs made from CFRP/foam-sandwich.

Fuselage

The pilot has a semi-reclining position in the comfortable cockpit. The one-

piece canopy hinges sideways and opens to the right.

For high energy absorption the cockpit region is constructed as a Kevlar/

carbon/glass fiber laminate, which is reinforced by a double skin on the sides

with integrated canopy coaming frame.

The aft fuselage section is a pure carbon fiber (non-sandwich-) shell, stiffened

by carbon fiber bulkheads and glass fiber webs. The landing wheel is retract-

able an features a mechanical respective hydraulic brake; the tail wheel (or

rubber skid) is fixed.

Horizontal tailplane

The horizontal tailplane consists of a fixed stabilizer with elevator. The stabi-

lizer is a GFRP/CFRP/foam-sandwich construction, the elevator halves are a

pure GFRP/CFRP shell. The automatic elevator trim is linked to the flap

actuating rod and is infinitely adjustable.

Vertical tail

Fin and rudder are constructed as a GFRP/foam-sandwich.

On request a water ballast trim tank with a capacity of 7.8 Liter (2.06 US Gal.,

1.72 IMP. Gal.) is provided in the fin.

Controls

On rigging the wing panels, the control surfaces are automatically hooked up.
