摘要

The present disclosure is directed to a retention assembly for a stationary gas turbine component. The retention assembly includes a first stationary gas turbine wall having a first surface. A retention boss extends outwardly from the first surface. The retention assembly includes a second stationary gas turbine wall having a second surface. A retainer is positioned between the first and the second surfaces. The retainer includes a base wall positioned adjacent to the retention boss. A first sidewall extends outwardly from the base wall, and a second sidewall extends outwardly from the base wall. A first arm extends outwardly from the first sidewall, and a second arm extends outwardly from the second sidewall. Each of the first arm and the second arm includes a plurality of convolutions. At least one of the plurality of convolutions is in contact with the second surface.
