Dudek Nucleon WRC, User Manual

excessive decrease of the attack angle. The trimmer system allows for 
considerable raising the rear part of the airfoil, thus effectively reducing its 
projected chord and surface area by some  30%, giving the paraglider a higher 
wing loading and increasing its speed. The centre of pressure also moves 
forward, adding enhanced pitch stability. Such a shift of loading gives the 
Nucleon an exceptional tuck-resistance and increases its projected aspect 
ratio, resulting resulting in much better performance, especially at high speeds. 
Should you require more lift, the rear section can be pulled down to restore an 
airfoil that will be effective along its entire chord. 

The WRC version (With Rod Concept) incorporates Dudek Flexi Egde 
technology.

Some minor modifications in the design (improving curvature among others) 
caused the wing to be more agile. Exchanging mylar reinforcements for elastic 
rods results in easier inflation and stiffens the leading edge. Increased speed 
ranges are another advantage of that improvement. ALC+ (new version of the 
ALC steering system) is more efficient and affects the canopy in more 
proportionate way. In effect steering appears to be smoother.

Those modifications should be welcomed especially by the competitors, 
seeking both for faultless launches and agility.

STRUCTURE

The Nucleon 3D body was designed in our 

CSG

 (Canopy 

Shape Guard) system, comprising many elements resulting 
in exceptional coherence and stability of the shape. Below 
you will find a short  description of CSG subsystems. 

Nucleon 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 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.

Nucleon’ 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.
