1.4.1 Descriptive
The “Ventus-3T” is a flap equipped, single-seat high performance powered sailplane
built from fiber reinforced plastic (FRP), featuring flaps and a T-tail (fixed horizontal
stabilizer with elevator, fin and rudder).
Wing
The six-piece wing with winglets is four-stage trapezoid in planform with triple-panel
“Schempp-Hirth” type airbrakes on the upper surface. The flaps are full-span and
act at the same time as ailerons.
The water ballast tanks are integral compartments in the forward section of the
wing. Every right and left wing contains 3 water ballast tanks. The water ballast tank
in the outboard panel is connected to the next tank in the inboard wing panel.
During rigging, the outboard tank is connected automatically to the inboard panel.
Their total capacity is approx. 178 liter (47.0 US Gal., 39.1 IMP Gal.).
The wing shells are a CFRP/foam-sandwich construction with spar flanges of
carbon fiber rovings and shear webs made from GFRP/foam-sandwich.
Fuselage
The pilot has a semi-reclined position in the comfortable cockpit. The one-piece
canopy hinges sideways and opens to the right.
The cockpit region is constructed as a Kevlar/carbon/glass fiber laminate in order to
achieve a high energy absorption.
The aft fuselage section is a pure carbon fiber (non-sandwich) shell for high
strength. The stiffening of the fuselage shell is made in the aft fuselage cone by
carbon fiber bulkheads and glass fiber webs. In the cockpit area the stiffening is
done by a double fuselage shell at the side with integrated cockpit frame and
seatpan supports.
The spring-suspended main landing wheel is retractable an features a hydraulic
disc brake. The tail wheel is fixed.
Horizontal tailplane
The horizontal tailplane consists of a fixed stabilizer with elevator. The elevator trim
is adjusted automatically when actuating the flap.
The stabilizer is a GFR /foam-sandwich construction, the elevator halves are a pure
CFRP shell.
