Keywords: integrated active fibres, composites, rotor blades, structural modelling, aeroelastic stability

A new model has been developed to characterise the structural behaviour of rotor blades that benefit from fully integrated active fibre construction. The beam wall is assumed to consist of a composite laminate with passive as well as active material plies. Standard theory describing the macro-mechanical behaviour of composites is employed to formulate the cross-sectional stiffness matrix and the actuation forces and moments in the rotor blade.
