Abstract
CRAFT Tech and the research group at the Advanced Aero-Propulsion Laboratory of Florida State University have worked on the jet noise problem and its control for nearly a decade in highly interdisciplinary teams. Leveraging our considerable expertise, facilities that were specifically designed for the type of research proposed here and our highly interdisciplinary research team, a multi-pronged approach is proposed that steps past the limitation of noise control via modification to the nozzle by taking a different approach to control of thermal and vibration loads attenuation for VTOL and/or JBD operations of the JSF F-35B by directing attention towards the modifications to the impingement plane. Specifically, the use of “smart” multi-functional structural materials, including piezoelectric, magneto-resistive and thermoelectric, will be computationally and experimentally investigated for providing vibration/noise control AND for harvesting energy from the unsteady pressure and thermal fields on the impingement plane. Key elements of the proposed research include the following: (a) Control of the Impinging Jet Flow-Noise-Vibration using Active-Adaptive Methods (b) Development & Application of Validated LES and Computational Aeroacoustics (CAA) Tools (c) Development of Piezoelectric Structures for Energy Harvesting and Noise/Vibration Attenuation and (d) Development of Thermoelectric Generators for Energy Harvesting from Thermal Gradients.
