AbstractA part of the noise research activities in Aviation Program Group of JAXA are introduced in this paper. Noise prediction around high-lift-devices of a civil aircraft is performed using UPACS (Unified Platform for Aerospace Computation Simulation)-LES (Large Eddy Simulation) code. Especially, noise from the flap edge and slats of high-lift-devices are known to the dominant source and these flows are investigated. From the careful observation of the computed results, the causes of both narrow and broadband noise became apparent. Current results give an insight to design the new low noise devices for the future high-lift-devices.
