Flutter mitigation of turbofan blades using viscoelastic patches
Flutter mitigation of turbofan blades using viscoelastic patches
Flutter as a self-feeding aeroelastic instability presents one of the biggest challenges in aero-engine designsto improve its aerodynamic and structural performance. This work presents a detailed feasibility study ofusing different viscoelastic patches as Constrained Layer Damping (CLD) enhancement for an aero-enginefan blade to reduce potential flutter risks. The static and dynamic responses of the different materials andconfigurations (thicknesses, layers and locations) are evaluated on both cruise and take-off/landingconditions. It is found that a double bi-layer 3M® ISD110 is the optimal choice of material for the CLDtreatment for the fan blade. The study also shows that an optimal CLD treatment of 15 % total surface areaof the blade at the root demonstrated a 36 % reduction in resonance amplitudes across the first six modes.

Abstract
Flutter as a self-feeding aeroelastic instability presents one of the biggest challenges in aero-engine designsto improve its aerodynamic and structural performance. This work presents a detailed feasibility study ofusing different viscoelastic patches as Constrained Layer Damping (CLD) enhancement for an aero-enginefan blade to reduce potential flutter risks. The static and dynamic responses of the different materials andconfigurations (thicknesses, layers and locations) are evaluated on both cruise and take-off/landingconditions. It is found that a double bi-layer 3M® ISD110 is the optimal choice of material for the CLDtreatment for the fan blade. The study also shows that an optimal CLD treatment of 15 % total surface areaof the blade at the root demonstrated a 36 % reduction in resonance amplitudes across the first six modes.
