TECHNICAL DESCRIPTION
Construction of the canopy:
The canopy of the MARVEL consists of 75 cells over the wingspan. The wingtips are
slightly pulled down and this produces a kind of stabilizer. The Marvel is a third rib
diagonal-construction paraglider. Every third main rib is attached to the 3 or 4
suspension lines. Between these main suspension ribs, intermediate ribs are
suspended by diagonal ribs. These diagonal ribs lead to top surface of canopy. This
construction ensures a smooth top surface and precise airfoil reproduction. The internal
reinforcements maintain the precise form of the canopy and provide stability. The cell
openings on the under-surface of the profile’s nose provide airflow into the glider.
Stretch resistant flares, integrated with diagonal ribs at the suspension points, ensure an
even distribution of load throughout the canopy. A stretch resistant Mylar reinforcements
combined with plastic rods on the leading edge help to keep airfoils in right shape and
this guarantees a high level of stability. Large cross spots allow effective airflow inside
the canopy, providing good re-inflation without reducing the profile accuracy. The Marvel
is made of the proven Nylon fabrics Porcher Sport Skytex Rip-stop 9092 E85A, 9017
E38A and 9017 E29A. Like any synthetic material, this can deteriorate through
excessive exposure to UV.
Rigging system:
The lines of the Marvel are made of proven strong and stretch resistant non covered
Aramid/Kevlar lines and brake lines are made from non covered Dynema lines. The
entire rigging system comprises individual suspension lines looped and stitched at each
end. The Aramid/Polyester main lines have strengths from 140 up to 230 kg. The
Aramid cascade unsheated lines have strengths from 45 kg up to 160 kg. The Dynema
brake lines have strengths from 60 kg up to 100 kg
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 link” (a Maillon which connects
lines and 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 C-risers to the brake handles.
