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: The energy storage flywheel device (6) includes a plurality of annular shaped composite sections (8) and an annular shaped insert (10). The insert (10) has a specific radial strength substantially greater than the composite sections' specific radial strength. The composite sections (8) and the insert (10) are alternately stacked such that they have a common axis of rotation. They are bonded to each other such that shear stress is transferred between the composite section (8) and insert (10). In some applications, the flywheel (6) may comprise at least one annular shaped metal matrix composite section (8).
