Advanced Technology MEMS-based Acoustic Array, Phase I

The proposed power reclamation technology has the potential to be transportable across multiple NASA facility classes as well as implemented across government-owned, industry and academic institution test facilities. The target market is acoustic energy harvesters for the aerospace industry and the AEH device can be adapted towards multiple aircraft or flight applications with minimal redesign required. Given the capability of the proposed device's ability to withstand harsh environments, the technology would support multiple NASA GRC facilities such as Aero-Acoustics Propulsion Laboratory, Small Hot Jet Acoustic Rig, Nozzle Acoustic Test Rig, Advanced Noise Control Fan Rig and NASA LaRC facilities such as the Curved Duct Test Rig (CDTR), and the Grazing Flow Impedance Duct (GFID). Beyond aerospace applications and customers, other potential markets include commercial aircraft, automotive and array-based feedback/embedded sensor systems for structural health monitoring. The investigators have an established relationship with Boeing and have identified other target customers such as Northrop Grumman, GE Transportation, Rolls Royce, Airbus, Honeywell, and Pratt & Whitney.
