Boson is a reflex canopy, featuring much speed, lift and agility, dedicated for PPGG (powered trikes) or foot-launched PPG tandems.

Design and purpose

Boson is a paraglider designed for experienced pilots, flying actively and often, who are well familiar with reflex wings behaviour and have fully mastered flying them.

The recommended minimum is 300 hours paramotor time and at least 50 hours of annual flight time.

It was designed with competing and record hunting in mind. It features considerable speed range, precise handling, and great efficiency.

The reflex traits of the Boson are distinct, nevertheless you can use the speed system at all trimmer settings (themselves having generous range BTW).

Design solutions

Boson was based on our proven and acclaimed Hadron Cabrio. Both the 3D body and planform remain similar, still many design solutions are new, from the length of lines to design of the risers, modified modified accordingly to experiences of the Hadron Cabrio pilots. Among others, the risers have been equipped with a speed system. Suspension lines have been shortened, positively influencing agility and launch behaviour.

When rising, the canopy moves smoothly and shows no tendency to overrun the pilot. The quality of the launch is ensured among else by stiffening the leading edge with elastic rods (FET – Flexi Edge Technology), which also guard it against collapses at high speeeds. The design incorporates other effective ways of load distribution too, related to the newest sewing techniques.

In comparison to Hadron Cabrio, Boson needs less power, easily noticeable in less sink with switched-off engine. Boson does require some attention from the pilot in turbulence, nevertheless remains safe and stable. For the steering comfort, it’s important to precisely adjust the steering lines’ length, accordingly to suspension height of the paramotor or a trike – every inch counts here! Steering system itself consist of our renowned and efficient 2D steering with TCT handles, plus additional TST‘s for the accelerated flight. As standard you can choose between three levels of the steering pulleys and docking magnets. Due to these improvements, operation
of the steering system is intuitive.

Already before its premiere the Boson piloted by Krzysztof Romicki and Wojciech Strzyżakowski as navigator has established a world record over a closed route (FAI triangle) for tandems of 280,41 km.

Boson, as all our paragliders, is manufactured entirely in Europe, in our Polish plant, so that we are able to supervise each step of its sophisticated production process.

Technologies, concepts

DRA - Dudek Reflex Airfoil

DRA – Dudek Reflex Airfoil -applied in PPG wings fully autostabilised arofoil, based on long years of research and experience. In our variant we managed to get rid of typical flaws associated with these aerofoils.

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.

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.

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).

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.

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.

TST - Tip Steering Toggles

Our original idea, featuring additional miniature handles that steer the stabilizers. It is a great improvement on long flights, when opened trimmers and full speedbar make steering much harder.

2D - Steering System

2D system is generally similar to the classic one – pilot has but two main steering handles to steer. However, it’s operation is significantly different.  Due to division of main steering lines (there are two for each side now, with one of them going outside of the pulley), an experienced pilot can modify steering progression according to his own preferences.

* Speeds are given as estimated for the middle wing size and the middle of its weight range. These speeds can vary within +/- 5 km / h depending on the size, take-off weight and additional factors such as air pressure and temperature.

** 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.
