Airframe noise simulation for landing gear and high-lift devices with CFD and FW-H

How airframe noise simulation works for landing gear and high-lift devices: tonal and broadband sources, CFD with a Ffowcs Williams-Hawkings step, mesh and record limits, array and tunnel validation, certification context and where AI surrogates help.
