Reasons and benefits of using JAXA Supercomputer System
To obtain airframe-proplusion integration design technology to enable airframe design with higher environmental performances of future aircraft application, CFD-based design/analyis have been conducted in this research. The high-fidelity CFD analysis of the whole aircraft configurations with the airframe-engine installation requires large computational resources. JSS enables the high-fidelity evaluations of the peformance in a timely manner and the technology developments.
Achievements of the Year
Based on specifications from the conceptual design for a 220-seat BWB with hydrogen-electric distributed engines, the wing-body design was performed. A BWB wing-body configuration that achieves the target lift distribution was successfully obtained.
