TECHNICAL DESCRIPTION
The internal reinforcements maintain the precise form of the canopy and increases
stability. The cell openings on the under-surface of the leading edge provide good
airflow into the glider. Stretch resistant support panels with diagonal ribs at the
suspension points ensure an even distribution of load throughout the canopy. Stretch
resistant Mylar strips on the top and bottom panels of the openings run the length of the
trailing edge defining the wingspan. This ensures optimized sail tension and guarantees
high canopy stability. Large cross ports allow effective airflow inside the canopy
providing good re-inflation without interrupting the profiles shape.
The Chronos is mainly made from proven high quality Nylon fabrics. Porcher Marine
Skytex Rip-stop 9092 E85A, 9017 E38A and 9017 E29A are the carefully selected
materials. Important care must be taken to maximize the life of your glider because like
any synthetic material, this can deteriorate through excessive UV exposure.
Rigging system:
The suspension lines are comprised of “cascaded top lines” (attached to the under-
surface),”cascaded middle lines” (cascade 2 to 2 top lines together on middle main
lines), and “main lines”. Main lines lead to the “quick links” (a small triangle carabineer
which connects lines to the risers). The “stabilizer lines” connect the upper stabilizer
lines on the outer suspension points with the quick link. The “brake lines” are not load
carrying suspension lines. They lead from the trailing edge of the canopy to the main
brake lines and run through the pulleys on the D-risers to the brake handles. Two black
marks on the main brake line indicate the two possible positions of the brake handles.
This adjustment allows for sufficient brake to be applied during flight and landing safety.
It also ensures that brakes are not too short causing permanent applied brakes during
flight (especially when fully accelerated). Having your brakes too short is dangerous!
Special attention is required before adjusting your brakes.
For differentiation purposes, the A-lines are coloured red, the brake lines are orange,
and all remaining lines are yellow. The main suspension loop on the bottom of the riser
is reinforced and covered red. This is where the main carabineer should be hooked in
connecting the risers to the harness.
The lines of the Chronos are made of strong and stretch resistant HMA Aramid/Kevlar
(yellow core) lines and PES/Dynema (white core) for brake lines. The entire rigging
system comprises of individual suspension lines looped and stitched at each end. This
contributes to the glider being incredibly strong.
The main Polyester sheathed ARAMID lines have strengths from 140 up to 340 kg. The
unsheathed Aramid upper cascade lines have strengths from 60kg up to 120 kg. The
Aramid middle cascade lines have strengths from 80kg up to 160 kg. The Dynema
brake lines have strengths from 100kg up to 240 kg. Add up the strength of all the lines
to understand the design of the Chronos provides you with safety and confidence.
