TECHNICAL DESCRIPTION
Construction of the canopy:
The canopy of the MACJET consists of 58 cells over the wingspan. The wingtips are
slightly pulled down and this acts as a kind of stabilizer. The MacJet is a second rib
diagonal-construction paramotoring glider. Every main rib is attached to 4 or 5
suspension lines. Between these main suspension ribs, intermediate ribs are
suspended by diagonal segments. 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 strip on the top and bottom panels alongside the openings and
running the length of the trailing edge defines the wingspan, together with an optimized
sail tension; this guarantees high form stability. Large cross ports allow effective airflow
inside the canopy, providing good re-inflation without reducing the profile accuracy.
The MacJet is mainly made of the proven Nylon fabrics Porcher Marine 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 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 D-risers to the brake handles. A mark on the main brake line
indicates the position of the brake handle. This adjustment, on the one hand, allows
sufficient brake to be applied during extreme flying situations and when landing, while
on the other hand, this ensures that brakes are not permanently applied to the canopy
(especially when fully accelerated). This trimming should not be altered. For
differentiation purposes the A-lines are coloured red, the brake lines are orange, all
remaining lines are yellow. 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 lines of the MacJet are made of proven strong and stretch resistant Polyester HMA
Aramid/Kevlar (yellow core) lines and PES/Dynema (white core) for brake lines. The
entire rigging system comprises individual suspension lines looped and stitched at each
end. The Aramid main lines have strengths from 140 up to 340 kg. The 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.
