Keywords: aircraft design, over-the-wing-nacellel-mount configuration

The effect of an Over-the-Wing-Nacelle-Mount airplane configuration for engine noise propagation toward ground is investigated. The nacelle position and shape are optimized to improve aerodynamic performance as well as to reduce ground noise level through numerical analysis and optimization technique.
