PROBLEM TO BE SOLVED: To provide a gas turbine engine frame for use in supporting a bearing that supports a turbine rotor. SOLUTION: At least one inner set of coaxial tapered inner holes extend axially through inner platform flanges and at least one outer set of coaxial tapered outer holes extend axially through outer platform flanges. The inner set of coaxial tapered inner holes define an inner conical surface and the outer set of coaxial tapered outer holes define an outer conical surface. Each of the axial spaced apart platform flanges may be circumferentially continuous or scalloped so as to have protrusions arranged spaced circumferentially apart. A strut has two inner sets of coaxial tapered inner and outer holes extending axially through the inner and outer platform flanges, respectively. COPYRIGHT: (C)2005,JPO&NCIPI
