*2.5. Tested Configurations*

The number of test configurations and their setup were designed considering the parameters identified as important for the survey. The aim was to perform a series of tests in different spatial positions of the dummy so that it would then be possible to evaluate the effect of force redistribution on the individual elements, based not only on the geometry of the structure itself but also on the different spatial body positions in which the rescue system would be activated. This will replicate the use of emergency parachutes, which are assumed to be activated in positions other than those for ideal and stable skydivers. Another important objective was to determine the effect of chest strap tightening. Nevertheless, the main feature of all tests will be the evaluation of the critical element in terms of its structural capacity. In other words, the critical element may not be the same in all cases. Based on the mentioned requirements, six different test cases have been established:


The meaning of "symmetrical loading" is the fact that a force of the same magnitude is applied to the left and right sides of the harness. The opposite is the case for the second and third tests, as their aim is to obtain information on the redistribution of the forces in the case of opening the canopy asymmetrically. Regarding test cases 1, 2, 3, and 6, the steel dummy has only one fixation point in the bottom between its legs. The position of equilibrium is determined just by the center of gravity and by adjusting the individual straps. Tilted cases 4 and 5 have generally fixed positions in the space defined. The setup of the configurations in the unloaded state is shown in Figure 7.
