Dudek Universal - Structure

The lower surface has a RSS (Reinforcing Strap System) applied in the
wing’s interior. RSS is an ballooning-independent reinforcements system,
made entirely of paragliding fabric, stiffening and stabilizing entire canopy
structure.
Universal’ aerofoil is another product of our DRA (Dudek
Reflex Airfoil) technology. It was calculated with our
previous experiences in mind and thoroughly tested with
numerical methods.
Properties of a reflex airfoil were described above. The suspension points
areas are additionally reinforced with laminated fabric so that loads are
equally distributed on three planes: vertically (through the ribs), diagonally
through VSS system and level through the RSS.
All crossports have been prepared using OCD (Optimised Crossports
Design) technology. Carefully designed shapes of the openings and their
optimal placement between stress lines guarantee very efficient pressure
distribution in the canopy and its quick inflation. These openings are scaled
together with the ribs, so that their replicability is flawless and they do not
disturb the aerofoil in any way. The Universal leading edge is closed to
airflow, and its precise shape is guarded by reinforcements of laminated
fabric.
Another feature of the Universal is the Flexi-Egde
technology. The leading edge is closed to the airflow,
and its precise shape is kept with laminated cloth
reinforcements, incorporating synthetic rods. The rods
make the leading edge stiffer and smoother, bringing improvements in many
areas - from easier inflation, through stiffening the canopy in flight to
improved general airflow.
Cell openings are positioned on the undersurface in the vicinity of the
leading edge. Their exact placement was very carefully selected, so that
they got maximum ram effect in as many flight situations as possible.
On the wingtips we placed the ACS (Auto Cleaning Slots) -
dedicated slots automatically removing dirt from inside the
wing.
Careful selection of modern fabrics and design solutions brings about great
strength and durability of the Universal. All materials used come from
marked production batches, and each production step can be verified down
to identification of specific worker and controller.
Universal is manufactured under new technology, utilizing precision of the
laser cutter. All stages of production process take place
in Poland under strict supervision of the designer himself,
thus ensuring highest European quality.
