A flow deflector blade primarily for mounting within the efflux of an aircraft propulsion fan so that a change of flow direction can be effected, includes a leading edge member, a trailing edge member, a leaf spring member of arcuate form connecting the two, and filler portions of rubber bonded to each side of the leaf spring member shaped to provide a desired blade contour.

A resiliently deformable flow deflector blade including a first surface, a second surface facing generally opposite to said first surface, a leading edge member, a trailing edge member, a leaf spring member connecting the leading edge member and the trailing edge member, and filler portions sandwiching said leaf spring member and shaped to provide a desired external contour at said first and second surfaces when the blade is undeformed, said leaf spring member comprising a leading region connected to said leading edge member near said first surface of said blade, a trailing region connected to said trailing edge member near said first surface, and an intermediate region between said leading region and said trailing region with said leaf spring being of arcuate form so that both when the blade is undeformed as well as deformed, said intermediate region will always lie adjacent said second surface of said blade, said filler portions being of a rubber material to adopt alternative desired contours when said blade is deformed.
