The
Ventus-2 range of sailplanes is one of the most successful model ranges
to emerge over the last decade. We have now decided to take this well proven
and high performance sailplane and develop the design to its logical next
step. Our state-of-the-art know-how in aerodynamics together with the additional
demands placed on the structure by modern competition flying (e.g. higher
wing loading) - and much more - have been incorporated in the production
of this new aircraft. The first place at the WGC 2003 in Leszno already
confirmed our work with the first participation impressively.
The Ventus 2cx sailplane is designed for racing in both
the 15m and 18m classes. By using optional "racing tips" (with winglets) of
1.82 m length, it may also be flown successfully in 15 m class contests,
because the 15 m wing likewise in not affected by any aerodynamic
compromises thanks to the ingenously selected separation point far inboard
on the wing (at y=5.68m).
The wing planform is thus optimized for either span, and
in conjunction with a new airfoil section, which was developed especially
for the Ventus 2 models, results in significantly higher L/D values as
compared with those of the predecessors.The Schempp-Hirth specific wing
geometry with multi-stage swept-back leading edge, two-stage bent-up 18
meter tips, flaperons over almost the full span and a very light control
system result - even with very high wing loadings - in phenomenal handling
qualities in circling and low speed flight, which were formerly thought
impossible. In so doing, the Schempp-Hirth design team, along with Dr. Mark
Maughmer and Karl-Heinz Horstmann, who designed the new 18 meter tips, and
Luek Boermans who designed the new tail airfoil, have designed a totally new
18 meter Ventus 2 !!
Standard features continue to include Flaperons, water
ballast controls and the very effective double-panel airbrakes which all
hook up automatically on rigging the inboard wing panels; a special device
(no loose pins) connects and locks the wing extension. When using a wing
stand, the assembly of the Ventus 2cx by two persons is very easy, as the
mass to be raised is hardly 30 kg on either end for each inboard wing panel.
