Abstract

The results of experimental and numerical investigations on cargo drop tests from a generic military transport aircraft configuration with open cargo bay are presented. The governing equations for experimental scaling are derived and it is shown, that a correct scaling is difficult to ensure. In the experimental simulations conducted in the DNW-NWB wind-tunnel trajectories of cargos with increasing complexity were measured three-dimensionally. The repeatability of the tests is very good and the accuracy of the optical tracking system is within 1% of the cargo-length. Based on the DLR-TAU-Code a process chain for the coupled solution of aerodynamics and flight-mechanics was developed. Its results match well the experimental data although attention has to be paid in specifying the ini-tial conditions because they may, as expected, have an impact on the solution.
