Abstract

A turbine engine including a first static structure comprising a first material defining a first thermal expansion coefficient and a second static structure comprising a second material defining a second thermal expansion coefficient different from the first thermal expansion coefficient. The first static structure and the second static structure are together disposed in adjacent arrangement along a load direction. The first static structure and the second static structure together selectively define a gap therebetween along the load direction based at least on a load difference between the first static structure and the second static structure.
