CRAHVI D4.3.8 & D 4.4.4a: Simulation results of the A321 DRI-KRASH model including cabin load database

Kurzfassung

This report presents the results of the simulations which were carried out with a full-scale Airbus A321 DRI-KRASH model for two different crash scenarios. The two selected scenarios are impacts on a rigid surface (with a forward velocity of 70 m/s and a downward velocity of 7 m/s) and on a 10° slope (with a forward velocity of 60 m/s and a downward velocity of 4 m/s). These simulations are a DLR contribution to CRAHVI Tasks 4.3 and 4.4 where the generated results are input in the CRAHVI cabin load database. Besides accelerations, velocities and displacements which are presented in detail for 5 selected frames, other KRASH simulation results (e.g. energy distribution, wing deformation and loading) are shown. In order to judge the passengers injury risk, a detailed ‘Eiband’ evaluation was carried out.
