How Fluid structure interaction Impacts Aerospace Engineering

Have you ever watched an airplane wing flex out the window during a bumpy flight? That’s Fluid-Structure Interaction (FSI) in action. FSI is a massive deal in engineering, especially in aerospace. When wind hits a plane's fuselage and wings, the physical material actually changes shape. This alters how the air flows around the plane, which can trigger nasty aeroelastic issues like heavy vibrations.
