CERAMIC MATRIX COMPOSITE RING SHROUD RETENTION METHODS - CMC PIN-HEAD

摘要

The present application is directed to a retention assembly (100) for a stationary gas turbine component (74). A first stationary gas turbine wall (84) defines a first wall cavity (112) and a second stationary gas turbine wall (74) constructed from a ceramic matrix composite defines a second wall cavity (102). A pin shaft (106) constructed from a first material includes a first shaft end (114) and a second shaft end (120). A pin head (110) constructed from the ceramic matrix composite includes a first pin head end (118) and a second pin head end (136). The pin head (110) defines a pin head cavity (116) extending inward from the first pin head end (118). The first shaft end (114) is positioned in the first wall cavity (112), and the second shaft end (120) is positioned in the pin head cavity (116). The second pin head end (136) is positioned in the second wall cavity (102). The first material is different from the ceramic matrix composite.
