Pratt & Whitney has teamed with scientists at Virginia Tech University to develop a tool for measuring thrust and emissions from gas turbine engines using lasers. The new technique, known as “filtered Rayleigh scattering for thrust measurement” (FRST), enables high-fidelity measurements of key parameters such as velocity, temperature, and density.

According to Raytheon subsidiary Pratt & Whitney, the FRST technique offers several advantages over traditional sensors and probes, which can cause blockages in airflow and are often difficult to install, especially on smaller engine cores with limited space.
