Morphing surfaces are highly demanded in various engineering fields due to their numerous advantages including improving aerodynamics, increasing stability, and reducing drag. Various technologies can be used to achieve this purpose. This paper presents the results of implementing a mobile spoiler using a shape memory alloy (SMA) actuator. SMAs are commonly used as actuators since they can reversibly change their shape after the application of thermal or mechanical loads. This study explains the mechanism of spoiler displacement, detailing how a bistable linear actuator with a maximum stroke of 5 mm can facilitate spoiler displacement of approximately 40 mm through a well-designed actuation system.

Abstract
Morphing surfaces are highly demanded in various engineering fields due to their numerous advantages including improving aerodynamics, increasing stability, and reducing drag. Various technologies can be used to achieve this purpose. This paper presents the results of implementing a mobile spoiler using a shape memory alloy (SMA) actuator. SMAs are commonly used as actuators since they can reversibly change their shape after the application of thermal or mechanical loads. This study explains the mechanism of spoiler displacement, detailing how a bistable linear actuator with a maximum stroke of 5 mm can facilitate spoiler displacement of approximately 40 mm through a well-designed actuation system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
