Technical Description
and consequently also more control and better
performance for the pilot.
Collapse behaviour
If there are any stability problems, RAST
prevents the canopy from suddenly and/or
completely emptying because the air is not able
to escape as quickly from the rear section.
However, it allows a sufficiently large area of the
glider to collapse to dampen and dissipate
energy. With RAST technology, collapses more
than 50% of the wing depth can only be
simulated with great difficulty and to date have
not been experienced in practice even in very
thermic and turbulent conditions.
A paraglider equipped with the RAST system
empties more slowly, has less tendency to turn
and opens more quickly.
This means that there is much less loss of
height than for the same design without RAST.
TIP
Do not be tempted by the increased safety
offered by RAST into taking greater risks.
Instead, you should use RAST as your
personal crumple zone if there is ever a
situation where you have misjudged
conditions.
Line system
The TWIN RS 2 has A, B, C and D- line levels,
which fork twice from the bottom (riser) to the
top (canopy) and which are divided into main,
middle and top lines. The individual line levels
are connected with one another using the
“handshake knot”.
The Maintenance and Service book has a
detailed line connection plan, showing the
individual
levels,
connections
and
line
descriptions.
With the brake lines, the individual levels are
bundled at the end with the main brake line. This
runs through the brake pulley on the riser and is
knotted at the brake swivel of the control
handle. There is a mark on the main brake line
which allows the control handle to be correctly
positioned.
The main lines are all attached to Maillon quick
links. The lines are fed through special elastic
rings and attached to prevent them from
slipping and to ensure that they sit in the
correct position.
WARNING
The paraglider is delivered ex factory with
the Maillon quick links secured using a
strong thread-locking compound Loctite
to
prevent unintentional opening. After service
work, quick links which have been opened
must be secured again against unintentional
opening.
