Abstract

A combustion liner assembly (2) for a gas turbine includes an outer liner (4), the outer liner having a flange (14) at a forward end. An inner liner (6) is disposed within the outer liner. The inner liner has a first inner wall (12). A venturi (8) includes a second inner wall (24), a venturi throat (10), and the first inner wall of the inner liner. A slip joint (16) is connected to the second inner wall. The slip joint receives the flange of the outer liner. Alternatively, or additionally, the combustion liner assembly includes a slip joint (30) between the inner or outer liner and an aft section (20).
