Supporting NASA's Aeronautics Research Mission Directorate, this project's technologies directly address requirements for a rapid-response, structural material system capable of quickly changing state for shape change, vibration control, or acoustic attenuation. CRG's electrically activated, variable stiffness composites present the opportunity to achieve all of these functions with a low-power solution to minimize the impact to the overall system and maximizing the overall performance gains. CRG's electrically activated, variable stiffness composites may have broad applicability for NASA in both aircraft and spacecraft applications where aerodynamics, flight control, vibrations, and noise are of concern. This project's technologies developed for NASA systems would directly apply to systems operated by other government and commercial enterprises. Government systems that would derive the same benefits would include but not be limited to fixed and rotary wing aircraft, atmospheric reentry vehicles, jet engine components, propulsion systems, and other future aircraft applications that will require adaptive structures, noise suppression, or active vibration damping technology operated by the Department of Defense. This technology's attributes for fixed and rotary wing aircraft should also yield a high potential for private sector commercialization for variable shape components for aircraft structures by Boeing, Lockheed Martin, and GE Aviation, Gulfstream, Bombardier, Cessna, and Dassault.
