Deployable wing mechanism

A deployable wing assembly for airborne missiles, aircraft or marine devices which comprise a body having wings thereon, each comprising an inner and an outer wing segment connected together to be generally co-extensive when deployed, and arranged to be stowed against the said body, and having first hinge means connecting an inner edge portion of the said inner wing segment to said body along a generally longitudinally disposed axis on the said body, and second hinge means connecting the outer wing segment to an edge portion of the said inner segment remote from the said first hinge means, said second hinge means being disposed generally at right angles to the surface of the said inner and outer wing segments at the said second hinge means, characterized in that the inner segment chord is large enough for the outer hinge to be in such a position as to permit efficient aerodynamic fairing, further characterized in that the said outer wing segment is long relative to the said inner wing segment and projects substantially beyond the inner wing segment whereby the wing segments can be given a large extension with high aspect ratio and good aerodynamic efficiency, further characterized by means to move and hold said inner wing segment angularly about the said first hinge means in relation to the said body, and means to move and hold said outer wing segment angularly about the said second hinge means in relation to the said first wing segment, whereby both wing segments can lie adjacent the said body with the inner or outer part of the wing segment extending beyond the inner wing segment, or can be deployed to selected positions.
