Most paraglider harnesses are equipped with a protection device that
damps the shock on the pilot’s spine during a hard landing.

Shock impact tests have to be executed on these harnesses in order to
prove the damping characteristics of it.

Harness attached to protector test dummy, in a similar way
like a real pilot in flight
Impact will be simulated by dropping the dummy from a
certain height.
To simulate the “in-flight” conditions, the airbag is inflated
with pressurized air equalling an airspeed of 7m/s. Inflation
has to be stopped at least 5 sec before impact.
Impact will be measured by an accelerometer mounted on
the dummy. (Impact measured in g’s)
Requirements: Minimun height: 1.5 m (shortest distance between harness and impact
surface)

Test ID resc depl
The deployment of the rescue system has to be ensured
in all circumstances, especially with a damaged glider.
The pilot has to be able to deploy the rescue chute with a
single pull out of the outer container, single handed and
in an anatomical favorable direction.
In order to simulate this, the test responsible deploys the
rescue seated in the harness. In a similar way as in real
flight. The deployment resistance is approximately
measured by the load cell, which is placed between the
hand of the test responsible and the rescue hand grip.
On the other hand inadvertent deployment has to be
fairly remote. Therefore a shear link has to withstand a
minimum load

The handgrip of the outer container has to be
connected to the inner container with a removable
loop in a way that it is possible to use the inner
container with different types of outer containers.
The connection between handgrip and inner container
has to have sufficient load capacity/structural strength
in any situation that may arise during normal
operation.
In order to verify this, the connection is tested on its
tensile strength by a default tensile testing setup.
In addition to this the breaking resistance will also be
measured.
Comment: Passed (although a duration of 10 s was not
obtained the test responsible considers this
test as passed giving the high break
resistance)
