Buffeting sull’Eurofighter Typhoon: origine aerodinamica e risposta strutturale

The Eurofighter Typhoon is one of the most advanced fighters ever designed in Europe. Its canard-delta configuration allows it to achieve very high angles of attack and maintain excellent maneuverability even in extreme aerodynamic conditions. But precisely under these conditions, a little-seen but extremely important phenomenon comes into play: buffeting. In this video, we clearly and technically analyze what happens when the flow around the delta wing and canards becomes highly vortical. Leading-edge vortices, flow separation, and fluctuating pressures generate unsteady aerodynamic forces that can excite the aircraft structure. These aerodynamic fluctuations translate into wing vibrations, wingtip accelerations, and even perceptible oscillations in the cockpit. Starting from experimental results and aerodynamic studies on the Typhoon, we will explore: how leading edge vortices form on delta wings the interaction between canards and main wing vortices why the pressure field becomes highly nonlinear at high angles of attack how fluctuating pressures generate buffeting how the wing structure responds in bending and torsion The goal is to understand not only what happens, but why it happens, connecting aerodynamics, structures, and flight dynamics.
