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.

AVweb’s DA40 NG Flight Trial
Diamond's diesel-powered DA40 NG is proving a popular choice for flight schools. In this video, AVweb's Paul Bertorelli explains the engine's details and gives the airplane a wring out in snowy London, Ontario.
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.
