Adjoint-Based Shape Optimization for Noise Reduction

ITAC and its partners propose to develop and demonstrate a computational technology and methodology tool for the concurrent automated shaping of aft airframe and nozzle geometries to reduce tactical aircraft jet noise without any performance penalties. The proposed technologies will lead to an integrated tool which inherently maintains critical aerodynamic performance while reducing the noise generated through the process. The ability of the proposed technology to simultaneously address the entire empennage and nozzle geometry represents a quantum leap over existing design tools.
