ACOUSTIC DETECTION OF CHARACTERISTICS OF AN AIRSTREAM MOVING OVER AN AIRFOIL SURFACE

摘要

Apparatus and associated methods relate to detecting turbulence of an airstream over an airfoil surface of an aircraft (10) using a sequence of acoustic transducers (14A-D) attached to the airfoil surface (18) of the aircraft along a path. Each of the sequence of acoustic transducers is configured to detect acoustic waves indicative of airstream condition proximate the acoustic transducer. A processor (16) is configured to determine, for each of the sequence of acoustic transducers, a level of turbulence of the airstream proximate the acoustic transducer.
