Check out this extraordinary video of a B-2 Spirit undergoing wing flutter testing in the ‘90s. In simplest of words, the air flowing over the wing can/does induce periodic vibrations in the wing structure, if the vibrations start to match the natural frequency of the wing structure, you get flutter. If flutter is unchecked, meaning the periodic force continues to increase the amplitude of the vibration present, the wing structure will eventually break. Dangerous but a pretty cool phenomenon. |

TechnologyARMY on Instagram: "This incredible footage shows the Northrop Grumman B-2 Spirit stealth bomber undergoing wing flutter testing back in 1995 — and it’s mesmerizing. 🛩️ Aircraft wings are designed to flex, but the B-2 took this to the next level. Built with nearly 80% composite materials, mostly carbon fiber, the Spirit became a milestone in aerospace engineering. These advanced materials replaced traditional metal alloys, making the jet lighter, stronger, and stealthier. From titaniu
