Ceramic matrix composite ring shroud retention methods-wiggle strip spring seal

A retention assembly for a stationary gas turbine component, comprising:

• a first stationary gas turbine wall comprising a first surface and a retention boss extending outwardly from the first surface;
• a second stationary gas turbine wall comprising a second surface;
• and
• a retainer positioned between the first surface and the second surface, the retainer comprising:
• a base wall positioned adjacent to the retention boss of the first stationary gas turbine wall;
• a first sidewall extending outwardly from the base wall;
• a second sidewall extending outwardly from the base wall;
• a first arm extending outwardly from the first sidewall;
• and
• a second arm extending outward from the second sidewall, wherein each of the first arm and the second arm comprises a plurality of convolutions, and wherein at least one of the plurality of convolutions is in contact with the second surface;
• wherein each of the first sidewall and the second sidewall contacts the retention boss;
• wherein the first stationary gas turbine wall is a turbine shroud mount and the second stationary gas turbine wall is a turbine shroud, wherein the retainer is radially inward of the first stationary gas turbine wall, and wherein the second gas turbine wall is radially inward of the retainer;
• wherein the plurality of convolutions comprises a first convolution and a second convolution, and wherein the base wall is positioned radially between the first convolution and the second convolution.
