The Product is a tear-resistant Nylon fabric: with a weight of 40g per square meter it meets the re-
quirement of tearing and tear strength while at the same time maintaining optimal porosity. “We’ve
been testing and re-testing for about 18 months, until we discovered the right fabric consistency”,
says Ernst Strobl, chief developer at U-Turn. It took over 40 DHV testings and even more droptests
in order to develop a material that is able to withstand all demands in all imaginable conditions. I
turned out that a certain relation between warp and weft produces the best results, although simple
and double incorporated were used for the Paratex RS. The double polyamide threads are weaved
into the fabric. The outcome is a material that greatly satisfies the demands of rescue equipment.
Due to the RIS you are guaranteed a very small opening time; the glider uses special bands which
cause the canopy and the “basis” not to lie on top of one another but constitute exactly calculated
input tension of the air duct. This positively affects the ampleness particularly in the first millise-
conds.
For the SECURE 3 XS/S the RIS turned out to be obsolete as tests have shown that the system only
generates advantages in opening times as of a certain canopy size. The SECURE Nano only weighs
1.6 kg, the flat surface is only 25 square meters. However the maximum pay load in accordance with
DHV testing is still 6,8 m/s 128,2 kg. At a take off weight of 80 kg the sinking rate is 5,3 m/s. The
SECURE 3 RIS in size XL with a flat surface of 42 square meters brings whole 2,4 kg to the scale and
in the DHV testing it holds 140 kg. Even at a pay load of 140 kg, the sinking rate is still only 6,1 m/s
and by 120 kg is the sinking rate 5,2 m/s.
