Innoveering is developing a non-invasive, portable sensing system that can measure and accurately quantify the flow characteristics (pressure, temperature, density, void-fraction, and/or velocity) of a multi-phase fluid within a 2-inch thick metal structure that is multi-species, compressible, highly turbulent, and highly transient. Advanced signal processing methodology and spatially distributed pitch-catch multi-frequency ultrasonics are adapted to measure and convert signals to engineering properties of interest. The methodology for velocity, pressure and void fraction measurement of the key physics associated with the real transient fluid flow event has been demonstrated. The targeted program is Strategic Systems Programs, which aligns well with Innoveering’s mission of developing revolutionary technologies that address sensing and control challenges in the aerospace, defense and energy markets.
Innoveering is developing a sensor system that is capable of operating uncooled in the ultra-high temperature environments (>2500 oF) of gas turbine engines to provide real-time turbine blade health monitoring information. A micro-distributed transduction approach in combination with novel processing enables real-time tracking of blade tip dynamics with high spatial and temporal resolution. Fabricated miniature probes leverage high temperature materials and exceed current size requirements. A frequency response in excess of 1MHz has been demonstrated in subscale gas turbine tests. The targeted application is the Joint Strike Fighter Program and improved understanding of integration requirements will assure a successful transition, and support Innoveering’s mission of developing revolutionary technologies that address sensing and control challenges in the aerospace, defense and energy markets.
