Morphing Resonators for Adaptive Noise Reduction

Cornerstone Research Group Inc. (CRG) proposes to advance materials and processes for suppressing radiated noise in an aircraft engine nacelle. CRG seeks to eliminate the complexity of current active systems through the use of CRG’s “smart” materials in shape memory polymer (SMP) based material systems. Design tools will be developed to computationally predict performance of morphing resonator concepts and provide a frame work to establish design methods to develop adaptive liners for all Navy aircraft. The morphing resonator concept will reduce broadband noise and tune absorption properties through flight regime changes. CRG will leverage much experience in morphing system design to realize the morphing resonator concept.
