Miniaturized Dynamic Pressure Sensor Arrays with Sub-Millimeter (mm) Spacing for Cross-Flow Transition Measurements, Phase I

Metadata Updated: May 2, 2019

The Interdisciplinary Consulting Corporation (IC2) and in partnership with the University of Florida (UF) propose a microfabricated, dynamic piezoelectric pressure sensor array with sub-mm spacing to enable high temporal and spatial resolution measurements of cross-flow transition in swept-wing, supersonic aircraft research. The proposal is in response to Subtopic A1.08 Ground Testing and Measurement Technologies, whereby the primary objective is "to develop innovative tools and technologies that enhance testing and measurement capabilities[HTML_REMOVED]" More specifically, the proposed innovation addresses critically unmet measurement needs of the Commercial Supersonics Technology (CST) Project of the NASA Advanced Air Vehicles Program (AAVP).

The proposed innovation is a highly miniaturized, dynamic piezoelectric pressure sensor array with sub-mm spacing for high bandwidth, high spatial resolution measurements of cross-flow transition. High-spatial resolution pressure sensors with sub-mm spacing provide a much-needed capability that does not currently exist among state-of-the-art offerings, enabling dynamic wall pressure measurement and identification of traveling and standing cross-flow modes. The proposed concept extends the basic design to high bandwidth, high-spatial resolution, dynamic pressure sensing via reduction in sensor geometry and integration of multiple sensors arrayed on a single chip. The end result is a miniaturized, highly-compact array of dynamic pressure sensors with backside contacts to enable a truly flush-mounted, smooth interface for flow measurement applications.
