Abstract

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.
