FreeX X-one Mode D'emploi page 63

The canopy of the X-ONE is made of extremely strong,
especially coated Porcher Marine fabric which when treated
properly (see chapter Care and maintenance) has proved to be
extraordinarily wear-resistant and airtight, so that you will enjoy
safety and excellent resale value of your X-ONE for a long time.
Diagonally stiffened Porcher Marine fabric was our choice for the
profile and ribs in order to guarantee maximum profile accuracy
in connection with the load optimised force penetrations for
induced forces. The profile of the X-ONE was particularly
calculated for the demands of a modern paraglider by the
aerodynamics specialist Dani Loritz and shows an unusually high
range of angle of attack.
Leading and trailing edge are reinforced with a polyester band,
air intake holes in the central part of the canopy are stiffened with
Mylar for best attributes for launching and high speeds.
The round shape of the cell openings was chosen to guarantee
a balanced tension ratio between upper and lower surface and at
the same time to keep the openings at the leading edge which
normally are disadvantageous to performance as small as
possible.
The X-ONE is not equipped with a stabilizer in the traditional
sense. It has been reduced to a winglet of the smallest possible
dimensions. In this way induced drag has been reduced and the
X-ONE has been provided with high directional and canopy
stability without bringing about unnecessary parasitic drag.
The parasitic line drag has been minimized by bifurcating
(branching) the lines between canopy and riser at three levels
and by adapting their diameters to the occurring loads. Only
high-quality Cousin Trestec, Super Aramid and dynema lines are
used.
These high-tech-lines meet the highest requirements of a
paraglider line in a special way: The outstanding tension stability
