Design and purpose

For the Halo, the keyword that guided us during the development phase was “ease of use”. The design goal was to facilitate the work of the instructors by facilitating the apprenticeship of the students. This requested extensive design work involving many numerical simulations. It was followed by numerous hours of trimming on the ground and in the air in a wide variety of conditions and flying spots, notably in the French Alps and in Poland.

Certification

All sizes have passed the certification procedures, receiving EN/LTF A category.

Design solutions

We paid special attention to details that, in our opinion, are of great importance.

Among other things, the separate risers for the “big ears” are intentionally longer than the others, which makes them easier to identify and use, especially for beginner pilots. The handles have been equipped with a double strap attachment system: Easy Keeper magnets and snaps, ensuring safety and comfort.

The Dudek Paragliders team strongly recommends regular ground training – regardless of the pilot’s level of advancement. They improve technique, increase the pleasure of flying, and provide a lot of satisfaction.

Careful selection of the modern cloth and design ideas made sure the Nemo 4 will have great durability. All materials used come from numbered batches, and each production stage can be verified down to identification of individual worker and supervisor.

Main lines are coded with colours according to recent PMA recommendations. More about this initiative on the Association website.

Design solutions, technologies and other functionalities are listed below in the Technologies section.

Construction solutions

Technologies, concepts

SN - Shark-nose

Airtakes designed and executed in Shark-nose technology meaning specific, concave shape of the reinforced profile area at its leading edge (the name comes form the very shape, reminding shark’s nose).

DOA - Dudek Optimized Airfoil

Dudek Optimized Airfoil It incorporates all our experiences stemming form previous designs and as a special feature is optimized with dedicated engineering software.

CSG - Canopy Shape Guard

CSG – Canopy Shape Guard – is our unique system controlling canopy coherence. It is because of this system that our wings are equally tensioned, smooth, stable and… simply remarkable.

LR - Laser Technology

Capabilities of the laser cutter allow for serial cutting of complicated shape narrow elements in large numbers, their optimal placing in relation to structure of the textile and highest possible precision of cut.

FET - Flexi Edge 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.

ACS - Auto Cleaning Slots

Dedicated slots automatically removing dirt from the wing tips.

MR - Mini-Ribs

Mini ribs speak for themselves – they are additionally introduced in the trailing edge between main ribs. Their task is to decrease ballooning (expanding and deformation of the cells) in this vital area af the aerofoil.

Keeping the rear part in shape reduces the drag induced behind trailing edge, thus improving general airflow and increasing airspeed.

OPCJONALNIE

TR - Trimmers

A trimming system for additional angle of attack regulation. Used mainly in PPG wings.
This system features replaceable trim straps. After prolonged or intensive operation they need to be replaced, as they get damaged by buckle edges.

Risers functionality

USED SOLUTIONS

TCT - Triple Comfort Toggle

An easy conversion from hard through medium to soft brake handles. Equippped with a swivel adn Easy Keeper.
Available standard (bigger) and short (smaller) versions.

EK - Easy Keeper

Indigenous way to hold the brake handles at the risers that keeps them firmly in place, while both attaching and releasing goes smoothly and easily. Used in most of our handles (TCT, ACT, SCT).

NP - Napy

Metal clasps for attaching the brakes to the risers.

SS - Speed System

A system of lines and pulleys sewn to the appropriate straps, connected to the bar hanging under the harness. It enables smooth adjustment of the angle of attack during the flight.

ELR - Easy Launch Riser

Split ‘A’ riser makes for easier launch and ‘big ears’.

* The basic rule is to choose the size of the wing so that the take-off weight is in the middle of the weight range. Less weight on the wing (lower range take-off weight) can be considered for foot take-off, when flying in calmer conditions, or when we want to improve economy. More experienced pilots who want to fly dynamically, have higher speed and fly in more demanding wind conditions can consider greater wing loading (take-off weight in the upper range). This is a common option among trike users.

** Note – the canopy significantly changes its behavior with increasing wing loading. The greater the loads, the greater skill and concentration of the pilot are required.
