The spectacular large scale experiment with the Phantom verified that the theoret-
ically determined load approach according to the RSK-LL describes the loads upon
impact relatively well. The design parameters used in Germany were therefore
verified.
Using the tests carried out at the SANDIA National Laboratories other mathe-
matical models to determine the load function could also be verified. Amongst
others the author was able to verify the mathematical models using the discrete
masses and springs described above. The modeling of fuselage of the approx.
17.6 m long military aircraft was carried out with 176 individual masses and
springs. The bursting load and mass distributions were assumed analog to the
