SYSTÈMES ET PROCÉDÉS POUR OBTENIR DES DONNÉES DE CAPTEUR INDICATIVES DES CARACTÉRISTIQUES DE VOL D'UN AÉRONEF UTILISANT UN CONVERTEUR D'ENERGIE ACOUSTIQUE

摘要

In an example, an acoustically powered sensor unit for obtaining sensor data indicative of flight characteristics of an aircraft is described. The acoustically powered sensor unit includes a housing having a first portion comprising a diaphragm and a second portion coupled to an exterior of an aircraft and. The diaphragm is configured to receive acoustic energy from an engine of the aircraft. The acoustically powered sensor unit further includes a voice coil actuator disposed within the housing and coupled to the diaphragm. The voice coil actuator is configured to receive kinetic energy by way of a vibration of the diaphragm and responsively generate an electrical power signal. The acoustically powered sensor unit further includes one or more sensors disposed within the housing and powered using energy from the electrical power signal. The one or more sensors are configured to obtain the sensor data indicative of flight characteristics of the aircraft.
