DETERMINING AIRCRAFT FLYING CONDITIONS BASED ON ACOUSTIC SIGNALS CAUSED BY AIRFLOW

Apparatus (12) and associated methods relate to determining airspeed and/or altitude based on acoustic waves caused by airflow. One or more acoustic transducers (14A-D) are positioned along an exterior surface of an aircraft. Each of the one or more acoustic transducers is configured to detect acous...

Zusammenfassung:	Apparatus (12) and associated methods relate to determining airspeed and/or altitude based on acoustic waves caused by airflow. One or more acoustic transducers (14A-D) are positioned along an exterior surface of an aircraft. Each of the one or more acoustic transducers is configured to detect acoustic waves caused by the airflow. The acoustic waves detected are indicative of an airstream condition proximate the acoustic transducer, such as, for example, airspeed and/or altitude. A processor (64) is configured to determine airspeed and/or altitude of the aircraft based, at least in part, on the acoustic waves detected.
