Due to recent advancements in electric propulsion, battery technology, and aerodynamics, eVTOL (electric Vertical Take-off and Landing) aircraft are heralded as the next frontier in the aviation industry. However, unlike their conventional counterparts, eVTOLs are much smaller in size and lighter in weight, creating challenges in navigating through turbulent atmospheric conditions at lower altitudes. Consequently, these aircraft must demonstrate exceptional agility to effectively maneuver through challenging weather conditions. Complicating matters further, eVTOLs rely on battery power, whose reliability and health status remain unpredictable and difficult to gauge precisely, thereby introducing additional complexities to their operation and maintenance. Therefore, innovative techniques are needed to ensure flight safety and battery health.
In this presentation, we will introduce novel fly-by-feel and battery health monitoring techniques based on integrated piezoelectric sensor/actuator networks. These techniques are aimed at making eVTOL operations safer and more efficient by providing real-time high-fidelity insights into flight mechanics and battery performance, thereby empowering operators to make informed decisions and mitigate potential risks effectively.
