Turbine frame

A turbine frame comprising:

• a first ring disposed coaxially about an axial centerline axis and having a plurality of circumferentially spaced apart first ports;
• a second ring disposed coaxially with said first ring and spaced radially therefrom, and having a plurality of circumferentially spaced apart second ports;
• a plurality of circumferentially spaced apart struts joined radially between said fist and second rings, each strut having radially opposite first and second ends, and a through channel extending therebetween;
• and
• a plurality of clevises, each of said clevises being disposed between a respective one of said strut first ends and said first ring in alignment with a respective one of said first ports for removably joining said struts to said first ring for both carrying loads and providing access therethrough;
• each of said clevises comprising:
• a base disposed against said first ring and having a plurality of mounting holes receiving mounting bolts therethrough to removably fixedly join said base to said first ring, said base having a central aperture aligned with said first port;
• and
• first and second legs extending away from said base and spaced circumferentially apart to define a U-shaped clevis slot receiving said strut first end;
• said first and second legs and said strut first end having a pair of spaced apart bores extending therethrough and receiving a respective pair of expansion bolts for removably fixedly joining said strut first end to said first and second legs, with said strut through channel being disposed between said expansion bolt pair and aligned with both said base aperture and said first port;
• and
• wherein said strut first end is disposed in said clevis slot in abutting contact with said first ring through said clevis base central aperture for carrying compressive loads directly thereto through said strut;
• and
• wherein said first ring includes a pair of axially spaced apart annular stiffening ribs disposed on opposite, axial sides of said clevises and said first ports for carrying loads between said struts and said first ring.
