Abstract: With the installation on the most recent aircraft of large engines with a bypass ratio of 10–12, the engine noise contribution to the overall aircraft noise was reduced, and airframe noise has now become one… read more here.

Abstract: This paper considers potential sources of error when using the Ffowcs Williams-Hawkings equation to make predictions of airframe noise, which entails a relatively low-speed, uniform incoming flow encountering geometry of varying complexity. Numerical simulations are… read more here.
