NASA Armstrong Flight Tests Shape Memory Alloy Onboard PTERA Testbed

PTERA flies with the outer portion of its wings folded 70 degrees downward. The wings were able to fold in-flight thanks to a shape memory alloy material, which is triggered thermally and used in an actuator to move parts of the wing.
