84 is formed with a pair of opposed radially inwardly converging cantelevered walls 86 which diverge axially rearwardly to meet a radially extending mounting flange 88 slots 90 fig3 and 5 are formed between the walls 86 and roof 92 of the socket clamp 84 to allow the walls 86 to act as flexible spring loaded biasing members to secure and clamp the outlet guide vanes 54 to the outer support member 48 as discussed further below similar flanged sockets 94 and socket clamps 96 are provided on the inner support member 46 as seen in fig2 a vane foot support 98 is integrally cast from a ceramic matrix composite material for supporting the radially inner and outer ends of the outlet guide vanes 54 within the sockets 76 94 and socket clamps 84 96 each vane foot support 98 is formed with an elongated generally hexagonal boss 100 having axially projecting ridges 102 an elongated pocket or channel 104 is formed within each boss 100 and axial ridge 102 for receiving a radial end portion 106 fig4 of each outlet guide vane 54 with a close fit the surface profile of each boss 100 generally matches the inner contours of the sockets 76 94 and the socket clamps 84 96 however each boss 100 is dimensioned to form a wedged interference fit between the.
