Shape Memory Alloy Locking Apparatuses
In an example, method for locking/unlocking a structure is described. The method includes attaching a first end of a pawl to a support assembly, wherein the pawl comprises a shape memory alloy (SMA) element configured to transition between a first configuration and a second configuration, and wherein the pawl is attached to the support assembly such that a second end of the pawl is movable between a locked position that prevents a rotatable shaft from rotating and an unlocked position that allows the rotatable shaft to rotate, activating the SMA element, thereby causing the SMA element to take on the first configuration and move the second end of the pawl to the locked position, and deactivating the SMA element, thereby causing the SMA element to take on the second configuration and move the second end of the pawl from the locked position to the unlocked position.
