Designed by JB Chandelier, Team Dudek and Jacques Peugeot (airframe sizing engineer), in close collaboration with Porcher Sport, the Run&Fly project had been a real challenge for us. We decided to set ourselves very aggressive goals in order to propose a really different, outstanding product. The main specifications were a total weight below 1 kg (the internal project name was 999gr), with speed and flare comparable to standard wings.
The wing also had to be affordable, in order to give access to the sky to a wider public. With such an ambitious target, we knew we couldn’t simply “make another single skin wing”: we had to think out of the box. As a result, the Run&Fly needed hours and hours of engineering discussions, debates, analyses, comparisons and numerical simulations, then obviously completed with a lot of flight & load tests.
Ultimately, the wing turned out to exceed our expectations. The biggest mono skin problems have been resolved; Run&Fly has good speed, nice landing and offers a lot of fun. Besides reaching our goals we also achieved a good glide ratio – above 6. Although we usually avoid publishing the glide ratio of our paragliders, because this parameter is sometimes subject to manipulation, we made an exception with Run & Fly. We want to give potential pilots at least a rough understanding of what they can expect from the fact that such an innovative wing exists.
Features and purpose
It is exceptionally light, so that you can carry the wing on your back during trail running or climbing sessions almost without noticing the load. It is so compact, that it fits in a 4-litre bag. The Run and Fly is perfect for trail running, hike & fly and necessary travelling, or just as a second wing you will always have with you (you can easily place it in your hand luggage while travelling by plane).
Run&Fly has excellent stability, coupled with organic, intuitive handling qualities, which makes the wing funny and easy to fly.
The harness is not part of the wing (set).
the wing inflates and stays over your head without pilot inputs,
no need to use A risers, no need to use the brakes in order to prevent the overshoot, you just start walking and voila! – your wing is stable above you,
the wing is easy to control once inflated, it’s reactive and much more forgiving than usual.
the wing is super reactive and intuitive – you have direct control,
the wing retains some micro-movement along the pitch axis but never shoots, wants to come back to straight flight as soon as possible without any unpleasant oscillations on the roll axis,
without pilot input, the wing is safe and stable,
deep spiral exit: without pilot inputs, the wing comes back quickly over the pilot’s head, with a very limited shoot.
The run&fly can make a nice flare. It’s essential to give as fast speed as possible during the final, to create a comfortable flare. If the pilot brakes too much, the flare will don’t work.
still under development, but we already know that Run&Fly is so easy and stable that it will certainly become the most popular way of descent in the mountaineering, while possibly changing the paragliding itself too,
according to the first students (complete novices), inflation and take off is totally intuitive,
students should learn faster than with a classic paraglider,
the reflex elements present in the design distinctly increase safety.
As is the case of our other special paragliders, we do not plan for the full certification of the Run&Fly in flight.
Despite the wing being very safe, as you can see on the SIV tests movie, this is not a typical free-flying paraglider, rather a glide-down wing. Both the design specifications as well as single-skin canopy mean that results of the classic EN/LTF tests most probably would be unjust.
However, the load test according to the EN norm was successfully passed, confirming the pilot’s safety up to 108 kg take-off weight.
