ABSTRACT:
A method and apparatus are disclosed for detecting the nature of fluid flow. Specifically, an omnidirectional aerodynamic sensor is disclosed comprising an omnidirectional aerodynamic drag force inducing probe, a force transducer and a signal processor. The force transducer is illustratively an array of strain gauges which detect forces in each of three orthogonal directions. Such forces are initially detected by the probe and then transmitted to the transducer. The transducer outputs electrical signals which the signal processor processes in order to determine, for example, aircraft angle-of-attack and angle-of-sideslip as well as wind speed and direction. The invention is especially useful in the field of aviation.
