Agile slalom wing

Description

snake-xx-intro

We are proud to present the very best of slalom canopies: Snake XX. It is a reflex sport paraglider for very experienced pilots, who are familiar with small, fast and very agile canopies with short brakes travel.
This is a demanding wing for demanding pilots.
Highest performance available for fast slalom courses, with possibly best agility.
It's truly a champion's wing.
Despite highest aspirations we did our best to preserve legendary stability, known from our other reflex paragliders.

Development of the Snake XX was focused on creating the best performance for more and more popular slalom competitions. Shark nose profile gives better airflow on the leading edge and higher air pressure within canopy at any angle of attack. The leading edge features synthetic rods (Flexi Edge Technology), considerably improving launch characteristics and protecting against collapses at high speeds. Additionally, front part of the canopy is further stabilised with the LE2R technology (Leading Edge Double Reinforcements). Higher aspect ratio, a bit more cells and modified arc gives result in better economy and agility of the wing.

The Snake XX however distinctly differs from the original Snake; it is faster, more agile and more efficient, yet definitely more demanding and not quite forgiving errors. It is dedicated for advanced pilots (at least 300 hrs paramotor time on similar class of wings, i.e. Snake, Hadron, Hadron 1.1). These requirements are not excessive; for your own safety please observe them rigorously.

The Snake XX is a 4-liner: high speed and stability can be successfully matched only in this riser scheme, allowing for precise pressure distribution within all reflex range.
B riser is anchored on a pulley, minimising speed system forces (previously it was a simple quicklink).   

At Dudek Paragliders we improve not only flight performance, but also constantly care for improvements in production quality. Accordingly, the Snake XX is produced from highest quality Porcher Skytex materials. Coupled with laser cutting, precise sewing and finish of every small detail this makes the Snake XX a masterpiece.

Obviously, the Snake XX is a member of new art family - the XX Four Elements, as Air, Water, Earth and Fire.
The paraglider is currently available in 5 sizes – 15, 16, 18, 20 and 22. We recommend to choose the size so that the wing load ratio stays within 6,5 - 9 kg/m2 range.

Great success of the original Snake forces us to maintain its production for the time being, so that proficient slalom pilots can freely choose a paraglider best suited to their needs.
 
The Snake XX as standard is equipped with both 2D and PA steering systems (PA stands for Power Attack, or Paap Kolar system).
Since the main steering is divided, experienced pilot can adjust progression of trailing edge action to his needs.

Lower line layers are made of sheathed lines, with non-sheathed rest.

The trimmer and speed systems change the angle of attack and raise the trailing edge of the wing, so that projected surface and chord are diminished by some 15%. This increases the wing loading and speed ofthe paraglider, while shifting the aerofoil's centre of pressure forwards increases its pitch stability. As a result, the Snake has better resistance to collapses and greater aspect ratio, meaning much better performance (especially at high speeds).

Lessened reflex of the Snake on closed trimmers is partly compensated for by its smaller size regarding the take-off weight. This results in higher wing loading.

Concepts and  technologies:

FET - Flexi Edge Technology

Snake's canopy features Dudek Flexi Egde technology. Precise shape of the leading edge is closed to airflow, and its precise shape is guarded by reinforcements of laminated cloth combined with synthetic rods, which significantly improve launch performance and protect the paraglider against collapses at high speeds.

CSG - Canopy Shape Guard 

Entire body of the Snake was designed under our CSG (Canopy Shape Guard) system, comprised of many subsystems resulting in exceptional coherence and durability of the canopy.

The Snake has an elliptical planform with slightly rearward swept tips. The cells are divided with ribs additionally supported by diagonal VSS (V-shaped supports) system. Such arrangement ensures a smooth top surface, exact aerofoil reproduction across the entire wingspan and yet more importantly,
minimal number of suspension points.

The lower surface features 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.

Most of all, the CSG oversees three key factors:

  • it forms the canopy, so that its shape remains as close to design as possible, with equally distributed loads. Lack of attention here would result in irregular surface with balloons instead of flat cells (unfortunately, stil quite a frequent sight, even on wings of 'renowned' manufacturers).
  • CSG stabilizes canopy in flight. Not a single pilot likes to see his wing moving like an accordion, especially as it does significantly hamper its performance.
  • CSG improves durability of the paraglider. Simple designs fairly quickly pay for locally accumulated stress with deformations - the most dangerous are those visible as lateral faults on the upper surface between suspension line rows. With the Snake XX that danger is practically eliminated.

DRA - Dudek Reflex Airfoil

Snake’s 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. It is a full bred reflex profile, with accordign characteristics.

Areas close to suspension points are reinforced with laminated cloth, and the cloads are equally distributed on three planes: vertical (through the ribs), diagonal through the 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.

Laser Technology 

Snake is manufactured in new technology, utilising capabilities of precise laser cutter. The enitre production process takes place in Poland under strict supervision of the designer, ensuring highest European quality.

Metal parts

All quick-links between risers and suspension lines are made of polished stainless-steel, with proven durability and resistance to corrosion. We use exclusively the attested quicklinks of French Peguet company.

ACS - Auto Cleaning Slots 

On the wingtips you can find dedicated slots, automatically removing dirt and rubbish from the canopy.

Risers:

Snake features four-way risers, equipped with:

  • 2D - multi-role steering handle (regular brakes)
  • TCT (Three Comfort Toggle) with Easy Keeper system
  • TST - Tip Steering Toggle
  • TEA - Torque Effect Adjuster
  • ELR (Easy Launch Riser) - launch assist system. This is specially marked A riser (red cover)
  • speed system affecting A, B and C risers, equipped with ball-bearing pulleys and specially suited line,
  • comfortable speedbar of the Easy Catch system,
  • trimmers with red trimmer tape, sporting a scale,
  • PA (Power Attack) system - a merger of the trimmers with regular speed system, so that pushing your speedbar automatically and simultaneously releases the trimmers,
  • various levels of steering line pulleys, depending on the suspension height used,
  • TCL  (Tip Control Line) - allows for heading adjustments and turns even at high speed, without distorting reflex profile too much. Steering is done with dedicated red line, fixed to the corresponding stabilo steering line.

Complete kit you receive includes:

Total worth of these additional items amounts to almost 200 Euro.
