Pratt & Whitney and Virginia Tech Pioneer Laser-Optical Thrust and Emissions Measurement for Gas Turbines
PARIS, June 19, 2023 /PRNewswire/ -- PARIS AIR SHOW -- Pratt & Whitney and Virginia Tech today announced a pioneering new technology for calculating thrust using lasers to enable high fidelity measurement of key gas turbine engine parameters including velocity, temperature, and density. Known as Filtered Rayleigh Scattering for Thrust measurement (FRST), this new optical instrumentation technique offers significant advantages compared to traditional sensors and probes, which will support the development of more efficient engine core technologies and could enable the measurement of non-CO2 particulate emissions in flight.
- "The ability to use lasers and optical sensors represents a major step forward in engine instrumentation technology and is testament to the longstanding collaboration within the Pratt & Whitney Center of Excellence at Virginia Tech," said Geoff Hunt, senior vice president, engineering and technology, Pratt & Whitney.
- Pratt & Whitney and Virginia Tech's joint research team successfully measured engine thrust using FRST optical techniques on a research engine in a test stand at Virginia Tech recording similar accuracy to that of traditional sensors and probes.
- Pratt & Whitney and Virginia Tech have a long-standing collaboration in propulsion technology development, with a focus on advanced instrumentation.
- The collaboration enables multiple graduate level projects and internships at Virginia Tech and Pratt & Whitney.
