Abstract:
1. A thermal expansion joint for a turbine engine, comprising: a second engine component having a generally radially-extending wall, the wall defining a slot; a first engine component disposed adjacent the second engine component and having at least one radially-extending surface adjacent the wall of the second component, the first and second components having differing thermal expansion coefficients; an insert having a stem with an enlarged head at one end and an end portion at the other end, the end portion having a radial diameter less than a diameter of the stem, the insert extending into an axial passage defined in the at least one radially extending surface of the first component, the axial passage having an enlarged section with a limited depth to receive a portion of the stem, resulting in an axial gap between the radial surface of the first component and the enlarged head, the insert aligned to be matingly received in the slot, the insert and slot respectively configured to allow for different thermal radial expansion between the first and second components while the second component is axially restrained by the gap; and a removable fastener retaining the insert to the first component.
