NUMERICAL EVALUATION FOR FAN-NOISE SHIELDING EFFECTS ON AFT-FUSELAGE MOUNTED AND EMBEDDED ENGINES
T. Ikeda¹, R. Furuya, Ryoyu Systems, Japan; M. Murayama¹; ¹JAXA, Japan
The fan-noise shielding effects are numerically compared for JAXA's low-noise aircraft design between the pylon mounted, and the boundary layer ingestion (BLI) engine configurations in a real scale at a take-off condition. Although both the configurations effectively shield fan noise by the airframe, the BLI configuration shows a better shielding capability through visualization.
