An aerofoil member is described which provides for a ‘smart Core’and flexible skin. The core comprises sheet material elements forming adjoining cells. The length of the elements can be changed, for example, using the piezo-electric effect, to alter the cross-sectional shape of the aerofoil without changing the peripheral length. Thus, the shape of the aerofoil may be changed to suit different flight conditions, or to mimic the effect of control surfaces.


1. An aerofoil member, comprising a flexible outer skin supported by an inner structural core, the core comprising a plurality of sheet material elements joined together to form a matrix of adjoining cells, at least one of the elements comprising an actuator actuable to adjust at least one of a size or shape of at least one of the elements and adjust a cross-sectional shape of the aerofoil member, at least one of the elements at a periphery of the core joined to the skin. 2. The aerofoil member of claim 1, at least one of the elements formed of piezo-ele...
