ABSTRACT:
A thermal load relief ring is disposed between the mating surfaces of adjacent cases of a gas turbine engine and secured thereto by a dowel pin or bolt to assure the concentricity of the cases. The bolt and dowel pin are configured to assure the concentric fit of the components. These configurations allow the cases to be fabricated from different materials to allow a lighter and less expensive case.
