Communicating Between Ducted Fans and the Wing

Aircraft quite often seem to get designed as an assembly of separate components, wings an entity unto themselves, engines or motors something attached to the fuselage or wings, and not always seen as a set of matched components until final assembly.  Quite often, different components are compromised from their optimal shape or structure because of the need to integrate them with other parts of the craft.  One group of researchers is finding ways to even cause components to begin communicating among themselves. Some parts, such as engines or motors, are hung on the wing or fuselage as replacements for earlier design variants.  The new powerplants may provide additional power, but they may also interfere with the overall performance and handling of the airplane. University of Illinois researchers led by Dr. Phillip Ansell, assistant professor in the Department of Aerospace Engineering in the College of Engineering has explored this subset of aeronautics and come to the conclusion that wings and propulsion …

EAS VIII: Dr. Jaiwon Shin Brings NASA to CAFE

The CAFE Foundation was honored this year to have Dr. Jaiwon Shin, Associate Director for the Aeronautics Research Mission Directorate. at the National Aeronautics and Space Administration (NASA), speak at the eighth annual Electric Aircraft Symposium.  His responsibilities at the agency, and his earnest regard for CAFE and its direction were evident during his talk. According to his NASA biography, “Dr. Jaiwon Shin…  manages the agency’s aeronautics research portfolio and guides its strategic direction. This portfolio includes research in the fundamental aeronautics of flight, aviation safety and the nation’s airspace system.”  Such tasks include overseeing the next generation (NextGen) air traffic control system, funding promising research projects, crafting policies that will assure ongoing progress in creating cleaner, safer flight vehicles, and coordinating such activities with congress and other government agencies. He pointed out that the first “A” in NASA stands for “Aeronautics,” the agency’s first major area of research and policy making.  Dr. Shin noted that the Wrights brought us powered, controlled …
