The specific objectives of the research are driven by five key technical challenge areas: power transmission and generation; control theory and information processing and modeling; fluid mechanics, dynamics, and aero-structural coupling; acoustics physics; and solid mechanics and advanced materials. These technical challenges are relevant to a broad range of industry and government programs, inherently force the integration of multiple disciplines, and involve technical issues that are beyond the reach of current prediction tools. Each of the technical challenges brings together the analytical methods and experimental validation data that are required to advance the state-of-the-art in a multi-discipline environment. Innovative solutions to these technical challenges, coupled with the increased ability to predict with certainty the solutions, will drive breakthrough technology for the rotorcraft industry.
