An end-to-end simulator for frequency scanning methods of filtered Rayleigh scattering (FSM-FRS) has been developed during the master thesis research at the German Aerospace Center (DLR). It can model several frequency scanning filtered Rayleigh scattering methods and predict the accuracies in measuring flow temperature, pressure, and velocity. In the context of the DLR project OSIRIS, FSM-FRS probe geometries have been conceived for simultaneously measuring airplane velocity, off-board temperature and pressure in-flight with the aim of replacing current measurement sensors in the future. Based on statistical uncertainties calculated using Monte-Carlo simulations, FSM-FRS techniques, probe configurations and settings have been optimized for maximizing the expected accuracies in the above-mentioned parameters. A validation experiment has been successfully performed for checking the reliability and usability of the end-to-end simulator. It was concluded that FSM-FRS accuracy is not sufficient to replace current airplane sensors, but this technique shows very good potential for further research.
