New system vibrates airplane wings to shake off the ice | A system that relies on tiny piezoelectric actuators embedded on the wing's surface. These actuators vibrate when a current flows to them, and have the ability to shake off the ice that forms above them.
While most planes use heat to melt ice that can form on the wing either before takeoff or during flight, the process is highly energy intensive and can impact engine efficiency. A new process from German researchers shakes the ice off instead.
