Bladeflutter
Bladeflutter is an aeroelastic phenomenon in rotating blades, in which aerodynamic forces interact with the blade’s structural bending and torsion to produce unstable oscillations, or flutter. If unchecked, these oscillations can grow and compromise structural integrity, performance, and control.
Bladeflutter can occur in rotorcraft blades, wind turbine blades, and marine propellers, especially when blades are
Analysis and prediction rely on aeroelastic models that combine structural dynamics with unsteady aerodynamics. Campbell diagrams,
Mitigation strategies include increasing structural damping and stiffness, redistributing mass and stiffness along the blade, tip
Bladeflutter remains a central concern in aeroelastic design, influencing blade development for aviation, wind energy, and
