<p>A rotatable turbine frame (48,50) includes annular outer and inner bands (48b,50b) having a plurality of circumferentially spaced apart struts (48a,50a) extending therebetween. An annular drive shaft (48d,50d) is fixedly joined to the inner band (48c,50c) for transmitting output torque therefrom, and the struts (48a,50a) are backwardly radially inclined relative to the direction of rotation of the frame (48,50) so that gas flow between the struts (48a,50a) tends to straighten the inclined struts (48a,50a) to effect a compressive load component therein. <IMAGE></p> |
