The concept aircraft that the GE Team in Phase One of NASA research came up with is a turboprop that is meant to weigh 14,600 pounds and achieve the goals set by NASA to reduce emissions and reduce fuel burn. Cessna was part of the Phase One study; the “skin” research in which Cessna serves as lead, is Phase Two.


SKIN IN THE GAME I


By David Jensen


NASA-sponsored research of skin on aircraft that are built of composites may expose unique benefits. It also could impact significantly aircraft maintenance.

hurdles. What’s more, on aircraft with composite structure, these skins could be made to change color upon impact, indicating damage, much like a bruise shows injury to human skin. They also could incorporate sensors that alert maintenance technicians of repair needs to a fuselage or wing. Cessna Aircraft engineers are now testing such new technology under a 27-month, $1.9-million contract issued in January 2011 by the National Aeronautics and Space Administration (NASA). The agency’s Fundamental Aeronautics Program is sponsoring the research through its Subsonic Fixed Wing (SFW) Project. The SFW Project’s mission is to “cause long-term thinking outside of the box [and] explore concepts in aviation aimed to increase energy efficiency and lessen environmental impact,” according to Dr. Mia Siochi, the contracting officer’s technical representative at NASA.
