✦ Synopsis

The scope of this article is to investigate the aeroelastic stability of wind turbine blade sections subjected to combined ¯ap/lead±lag motion. The work is motivated by recent concern about destructive edgewise' vibrations of modern, half-megawatt-scale, blades. The aeroelastic governing equations derive from the combination of a spring±mass± damper equivalent of the structure and a non-stationary' aerodynamic model. The aerodynamic model used in the present context is the differential dynamic stall model developed at ONERA. The resulting equations of motion are linearized and their stability characteristics are investigated in terms of the system entries, expressed through suitable, non-dimensional, structural and aerodynamic parameters.

Equations for large amplitude coupled flap-lag motion of a hingeless elastic helicopter blade in forward flight are derived. Only a torsionally rigid blade excited by quasi-steady aerodynamic loads is considered. The effects of reversed flow are included. By using Galerkin's method the spatial depen
