Tao Systems proposes to develop a sensor system providing quantitative in-flight boundary layer flow characterization with fast response, low volume, minimal intrusion, high accuracy and robustness to weather conditions. Aviation loss of control (LOC) accidents often results from stalls and uncertain weather/flow conditions, often at low altitudes e.g., take-off/landing. We propose to develop a robust sensor system to assess stall conditions and surface boundary layer phenomena through the use of a low-weight system consisting of surface flow sensors that: (1) use a robust transduction mechanism, (2) is operable under adverse weather conditions, e.g., rain, (3) has a one-time lifetime calibration with a minimal maintenance schedule, (4) provides monotonic output with speed and flow angle, and (5) relatively insensitive to environmental parameters such as flight altitude, pressure, temperature, and density. This technology increases sensor robustness as output for control feedback for a wide range of flight regimes and flow conditions.
