TECHNICAL DESCRIPTION
Construction of the canopy
The canopy of the ARAVIS consists of 50 cells over the wingspan. The wingtips are slightly
pulled down and this produces a kind of stabilizer. The Aravis is combination three rib
diagonal-construction paraglider. Every main rib is attached to the 3 or 4 suspension lines.
Between these main suspension ribs, intermediate ribs are suspended by “bridge” diagonal
ribs system. These diagonal ribs lead to 80% of height of ribs. This construction ensures a
smooth top surface and precise aerofoil 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. Nitinol wire-rods on the leading edge and on C diagonals help to
keep aerofoils 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 Aravis is made of the proven Skytex 27 HF & Double Coating, Skytex
32 Universal, Nylon fabrics from Porcher Sport. Like any synthetic material, this can
deteriorate through excessive exposure to UV.
Rigging system
The lines of the Aravis are made of proven strong and stretch resistant covered
Aramid/Kevlar lines and Dyneema lines. The entire rigging system comprises individual
suspension lines looped and stitched at each end. The lines have strengths from 50 kg up
to 200 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.
For differentiation purposes the main A-lines are coloured red, the main B-lines are
coloured yellow, the main C-lines are coloured blue and the main brake lines are orange.
Also the main suspension loop, on the bottom of the riser, is covered red. This is where the
main karabiner should be hooked in, which then in turn connects the risers to the harness.
The Aravis is equipped with 4 risers per side (A, A1, B, C). The two central A-lines per side
are attached to the main A-risers while outermost A main lines are attached to
A1 risers. The 3 B-main lines and the stabilizer lines are attached to the B-riser.
The 3 C-main lines to the C-riser.
The line connections are made to triangular Maillons (quick links) fitted with a rubber
”O - ring” in the form of a ”figure eight” which prevents any slipping of the lines on the quick
link. See line plan for details.
