8.2 Inner container

The inner container has been developed on the G-Force Trainer and is the result of 5
years of experience with rescue system deployements under centrifugal force. These
are its most important characteristics:
Flat construction design, but not necessarily with the least possible volume
Tests have shown that the container can be pulled out of the harness' rescue
compartment much easier and with less effort than cube-like shaped containers,
sometimes even if they have a smaller volume.
Also, the flat container deforms much more when it is pulled out by the pilot in upward
direction. It bends up so that the risk of getting caught in the harness is reduced as
far as possible and the reserve parachute can be deployed with considerably less
effort.
Tapered shape with rounded edges
The tests have also shown that pulling out the first third of the container requires the
most effort. Accordingly, the likelihood of the inner container getting stuck inside the
harness is highest during the first phase of deployment. The inner container of the
Krisis Karre is thus designed to have a very low profile without rough edges in the
front area so that the risk of getting caught in the harness is minimised. However, it
must be noted that problems associated with deployment are also significantly
influenced by harness design.
No dangerous gaps on the surface of the closed container
The container of the Krisis Karre has been designed in such a way that the line
bundles cannot get outside the closed container. There are currently many systems in
the market that cannot guarantee this. Especially the popular lover leaf style
containers are prone to this. When the line bundles exit the container too early during
deployment, this can lead to dangerous situations. The closed Krisis Karre container
does not have any gaps on the surface so that its functionality is guaranteed even
under high centrifugal forces and in extreme conditions.
Redundant container lock
The container with the line bundles is double-locked for improved operational safety
and to prevent an early and thus uncontrolled opening of the rescue system.
This is a further measure to avoid the entangling of the reserve in the paraglider lines
as it contributes to a defined deployment after the release.
Fabric-coated rubber bands
If the container is locked using packing rubber bands or rubber bands without
protection, there is a risk of early breakage as they are often not strong enough –
especially at high centrifugal forces – and might thus release the lines or the canopy
from the inner container too early or the reserve parachute might even remain inside
the harness while only the container is pulled out of the compartment.
Therefore, the inner container of the Krisis Karre is equipped with fabric-coated rubber
bands with a diameter of 3 mm. The rubber bands can be easily replaced when
necessary due to aging.
