Constructive Characteristics - Kortel Design Krisis Karré 100 Mode D'emploi

Rev. 5
Offset release shackle at the inner container
Rescue system deployments on the G-Force Trainer showed that the intuitive pulling
direction of a pilot in a stressful situation is often upward, as with the handbrake of a
car. However, this direction is disadvantageous to pull the reserve parachute out of the
harness and it increases the release force significantly. The release shackle at the
inner container of the Krisis Karre is designed in such a way that the release force
remains low even in this „worst case" so that the reserve system can be pulled out of
the harness reliably and fast.
Seperate canopy lock
The rescue system container of the Krisis Karre is designed in such a way that it first
releases the lines and the canopy is released only after they are fully stretched. This
provides for a defined canopy opening and further reduces the risk of an entangling of
the reserve in the paraglider lines in SAT-like rotations.
URGENT RECOMMENDATION
Today, also some harness manufacturers offer containers suitable for their harnesses.
The Krisis Karre has been certified in combination with its inner container and many of
the container's details contribute to an optimal performance of the system. Tests
showed that the DC container performs significantly better in many aspects than the
container that comes with a harness. 5 years of experience with rescue system
deployments on the G-Force Trainer (a centrifugal force simulator) have been
incorporated into the development of the container. We therefore urgently recommed
the use of the original DC inner container and to let the release handle be attached to
it by an authorised specialist if necessary. Should sewings be required, you can
contact Kortel Design for assistance. We are offering this extra service as the
interfaces of the different components are not standardized in paragliding. A careful
adjustment of all components in addition to the obligatory compatibility test thus
optimises your system significatly!
WARNING (according EN certification rules)
Use of this parachute with any alternative inner container: the speed of opening and
opening shock test has been completed using the inner container supplied.
Use of any other inner container may produce different results (including failure)

8.3 Constructive characteristics

Diagonal suspension and flight direction
The diagonal „diamond" configuration is one of the main innovations that make the
originally non-steerable concept of a cruciform canopy steerable. Due to the diagonal
flight direction, the calculative aspect ratio increases from 1 (square) to 2 (diagonal
square). As the Krisis Karre has a defined forward movement, the low sink rates are
not only influenced by the drag coefficient but, similar to a wing, also to the lift
coefficient. The higher aspect ratio that results from the diamond configuartion is
essential for the resulting flight and gliding qualities. The diagonal suspension also
makes it possible to attach the brake lines at two edges of the rescue system canopy.
