Abstract
JAXA FQUROH+ Research aims at raising the technical maturity level of the noise reduction technology for high-lift devices and landing gear, which draws international attention to reduce noise in areas around airports, to a level applicable to future development of aircraft and related equipment. One of the objectives of the research is to verify the feasibility of practical noise reduction concepts and design methods based on advanced computational simulations. In this work, operation check and debug of the modified CFD code on JSS is conducted.

Reasons and benefits of using JAXA Supercomputer System
The JSS is used to understand detailed physics of noise generation, and to optimize noise reduction designs. The FQUROH+ Research aims to accelerate technology maturity of airframe noise reduction methods using advanced high-fidelity computational simulations on the JSS's high performance computing platform and to demonstrate the high-fidelity design technologies through flight tests. Computational simulations using the JSS make it possible to design low-noise devices by understanding detailed physical phenomena, which is difficult to obtain only with wind tunnel tests.
Achievements of the Year
The pre-processing in the CFD code was modified with debuging through application to a large scale practical problem on JSS.
