Abstract
A method, system, and sensor for air flow sensing. The system can include a cantilever, a transducer, and a processing module. The method can include measuring beam deflections of one or more cantilevers, extracting information about air flow, and determining one or more of an airspeed, an angle of attack, and a sideslip, based on extracted information. The system and method can exploit nonlinearities in the behavior of the cantilever in fluid flow.

11. An airflow sensing system for measuring flight data, comprising:
-
a cantilever having a cantilever surface, the cantilever being positioned on a surface of a vehicle; a transducer configured to detected deflections of the cantilever and produce an output based the deflections; a processing module in communication with the cantilever; wherein the processing module is calibrated to translate the output from the transducer into one or more of an airspeed, an angle of attack, and a sideslip. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
