Description

To study the properties of three-dimensional flying debris, the motions of three types of plate-like debris with different aspect ratios were simulated computationally by solving 6 degree-of-freedom (DOF) motion equations and experimentally measuring six components of aerodynamic forces in a wind tunnel. The results of this simulation for a wide range of initial starting angles of attack indicated that the extension region of the trajectories of flying debris changed depending on the Tachikawa number, Ta; aspect ratio, H/B; and wind speed, U. Furthermore, it was clarified that the mean velocities for the x and z directions were not affected by rotation motion. The ensemble-averaged motion equation for 2 DOF showed that the mean velocities of the debris depended on the Tachikawa number and the averaged drag coefficient, and the lead formula fit to the results of the 6DOF motion simulation very well.
