A review of recent advances in the use of surface integral methods in Computational
AeroAcoustics (CAA) for the extension of near-field CFD results to the acoustic far-field is …

This paper describes a two-dimensional formulation of the Ffowcs Williams and Hawkings
equation in the frequency domain. By assuming subsonic rectilinear motion of all acoustic …

Numerical investigations are performed to investigate the interaction effect between the rotor
and fuselage on the aerodynamic and aeroacoustic characteristics of the XV-15 tiltrotor …

The acoustic analogy was introduced into acoustics by Lighthill in 1952 to understand and
predict the noise generated by the jet of an aircraft turbojet engine. The idea behind the …

The paper makes a contribution to the clearer understanding of the physical meaning and
domain of applicability of the Ffowcs Williams–Hawkings (FW-H) and Kirchhoff aeroacoustic …

A new formulation for the Ffowcs Williams–Hawkings quadrupole source is presented for
helicopter-rotor noise prediction. The formulation is a far-field approximation which is exact …

To reduce the aerodynamic noise and radar cross section (RCS) of the helicopter rotor
without sacrificing its aerodynamic characteristic, a comprehensive optimization method …
