Technical Description
without any tendency to overshoot or launch
the pilot unintentionally.
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.
Line system
The APUS RS has A, B and C- 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
Please make sure that you comply with
the service intervals for the lines which
are given in the Maintenance and Service
book. These must be observed under all
circumstances.
The lines used for the APUS RS have a
diameter of less than 1mm. There is a
risk that the lines will break if they are
handled incorrectly or if the service
intervals are not observed.
