Low-Cost, Low-Power Sensor For In-Flight Unsteady Aerodynamic Force and Moment Estimation

Tao Systems and University of Minnesota propose to develop a sensor system providing sectional aerodynamic forces and moments with fast response, low volume/size/power requirements for ease of installation, and minimal calibration requirements. Aviation loss of control (LOC) accidents often result from stall and uncertain weather/flow conditions, often at low altitudes e.g., take-off/landing. The sensor system: (1) uses a robust transduction mechanism, (2) has a one-time lifetime calibration requiring minimal maintenance, (3) provides monotonic output with speed and circulation, and is (4) relatively insensitive to environmental parameters such as flight altitude, pressure, temperature, and density. This technology provides real-time output for energy state awareness under both nominal and off-nominal flight conditions.
