On an airliner, engines are a source of noise heard on the ground, but so is airflow over landing gear, flaps and slats. Using massive supercomputers to model airflow, NASA is seeking ways to reduce such noise. This AVweb video explains the project.

Why the Dragon’s Split Second Launch Timing is a Must
In this AVweb VODcast, former NASA lead flight director and KITPLANES editor at large Paul Dye explains why this week's launch of the Crew Dragon spacecraft requires split-timing. It's a little like driving a really fast car with only a few quarts of gas in the tank.
Nice tech, but I thought that drag was a good thing when descending and slowing for landing?
Is this a rerun? Haven’t we seen this footage before?
First, is all this research time & money for the benefit/comfort of the pax?
surely not folks on the ground.
Really, is the gear down noise the most bothersome of your trip?
Comments please.
