Aeronautical research. The Aeronautics part of the National Aeronautics and Space Administration isn't just a bygone relic. Their most visible projects are their space side, but they do a fuckton of research into making planes fly better/faster/safer. They do research on new control methods of planes, new geometries, how weather phenomena affect planes, etc.
