NASA tests Nitinol shape-memory alloy for folding wing
February 12, 2018
Polymet was excited to work with NASA Glenn Research Center to extrude samples of their unique alloy for testing.
“In this video, NASA conducts a flight test to investigate the ability of a shape-memory alloy to fold the outer portions of wings in flight. NASA Glenn Research Center in Cleveland provided the nickel-titanium alloy, and worked with Boeing Research & Technology to integrate the material into an actuator. The alloy is triggered by temperature changes to move the outer portions of wings up or down during flight. The ability to fold wings to the ideal position for various flight conditions may produce several aerodynamic benefits for both subsonic and supersonic aircraft.”
