FLUTTER DETECTION SENSOR

Systems and methods for monitoring aerostructures are provided. In various embodiments, a method for monitoring an aerostructure may include: receiving a signal from a pressure sensor (192, 193), the pressure sensor (192, 193) located downstream from the aerostructure; performing a time frequency an...

More Information
Summary:Systems and methods for monitoring aerostructures are provided. In various embodiments, a method for monitoring an aerostructure may include: receiving a signal from a pressure sensor (192, 193), the pressure sensor (192, 193) located downstream from the aerostructure; performing a time frequency analysis on the signal to calculate a power level over a range of frequencies; monitoring the power level over the range of frequencies; and determining a susceptibility to a flutter condition based on the monitoring the power level.
