Gas turbine engine structural frame with multi-yoke attachment of struts to outer casing

In a gas turbine engine including a high pressure turbine and a low pressure turbine having respective outer casings, a structural frame component, comprising:

• (a) an annular outer shell attached to, and extending between, said casings of said high and lower pressure turbines;
• (b) an annular inner central hub concentric with said outer shell about a common axis;
• (c) a plurality of circumferentially-spaced struts extending between the outer shell and central hub, each strut being attached at its inner end to said central hub;
• and
• (d) a multi-yoke attachment including a plurality of yokes, each yoke including a clevis releasably attached between said outer shell and an outer end of a respective one of said struts, said clevis having a one-piece construction and including
• (i) an inner bifurcated portion attached to opposite sides of said outer end of said strut, and
• (ii) an outer base portion integrally connected to said inner bifurcated portion and attached to said outer shell, said outer base portion being disposed in an outer overlying relation to said outer end of said respective one strut outwardly from and attached to said inner bifurcated portion.
