Reasons and benefits of using JAXA Supercomputer System
To perform numerous cases of topology optimization and obtain numerous design idea.
Achievements of the Year
Topology optimization was applied to the design of the wing structure of a transport eVTOL, and a comprehensive study was conducted from design to manufacturing. As a result, it was confirmed that by appropriately converting the optimal reinforcement plan(Fig.1) obtained by topology optimization into path data(Fig. 2) for TFP (Tailored Fiber Placement), it is possible to fabricate an integrated carbon fiber preform(Fig. 3), which can be fabricated as a composites structural member(Fig.4).
