    Abstract: PROBLEM TO BE SOLVED: To manufacture a light air foil, having rigidity adaptable to a load generated by a gas turbine engine, at a low cost. SOLUTION: An air foil 30 of which, for example, a fan outlet guide vane consists has a body with geometrical cross section comprising a first wall 44; a second wall 46 arranged opposite to the first wall; a front edge 48; a rear edge 50 arranged opposite to the front edge; and at least one of cavities 52 and 54. The cavities 52 and 54 are formed between the first and second walls 44 and 46 and between the front and rear edges 48 and 50. The air foil 30 is extrusion-molded by using non-continuous reinforced aluminum such that the body with geometrical cross section is extended between first and second ends.

    Abstract: PROBLEM TO BE SOLVED: To provide an aluminum alloy having excellent mechanical properties at the temperature up to about 300 deg.C. SOLUTION: This aluminum alloy strengthened by high strength dispersion consists of an aluminum solid solution matrix strengthened by the dispersion of particles based on a compound Al3X having an L12 structure. Various alloy elements are used so that the matrix and particles have similar lattice constants, thus the lattice constants of the matrix and particles are modified. The alloy is produced from a melt by rapid solidification.

    Abstract: A fan blade comprises an airfoil portion and a sheath portion. The sheath portion has a sheath head section, a first sheath flank, and a second sheath flank, both flanks extending chordwise from the forward sheath section. The sheath portion is bonded to the airfoil portion such that the sheath head section covers the forward airfoil edge, defining a blade leading edge. The first sheath flank covers a portion of the first airfoil surface proximate the airfoil forward edge, jointly defining a blade suction surface. The second sheath flank covers a portion of the second airfoil surface proximate the airfoil forward edge, jointly defining a blade pressure surface. The first metallic material is an aluminum alloy containing between about 0.5 wt% and about 3.0 wt% of lithium.

    Abstract: A fan blade includes first and second titanium portions that are secured to one another with an aluminum alloy braze. A method of manufacturing a fan blade includes providing first and second titanium portions, applying an aluminum alloy braze to at least one of the first and second titanium portions, and heating the fan blade to melt the aluminum alloy braze and join the first and second portions to one another to provide a fan blade with an airfoil exterior contour.
