Abstract

Japan Aerospace Exploration Agency is currently investigating feasibility of the Mars Aero-flyby Sample Collection as the capturing Martian dust particles mission. In our previous work, trajectories and thermal analyses for spherical dust particles till particles reached the capturing device were computed. Martian dust particles are not all spherical but have several shape variations. In this study, the trajectories and the temperature elevations of the disk-shaped particles were numerically investigated. As results, the trajectories were deviated and the temperatures were elevated whether the particles face the disk or the lateral side to the relative flow velocity direction. One can find that the projection area of the disk-shaped particle has a great effect on the trajectory and the temperature elevation. Both of the disk-shaped and the spherical particles, the tendencies of the reached density maps are similar. On the other hand, the reached temperature maps showed the area divided into the high and the low temperature by the difference of the projection area or the stable flight attitude of the disk-shaped particles.
