AIRFOIL VANE, BAFFLE FOR AN AIRFOIL VANE ASSEMBLY AND METHOD OF ASSEMBLING A CERAMIC MATRIX COMPOSITE AIRFOIL VANE

摘要

An airfoil vane (100) includes an airfoil section (106) including an outer wall (108) that defines an internal cavity (110); and a baffle (112; 212; 312; 412) situated in the internal cavity, the baffle including a baffle wall (113; 213; 313; 413) that defines a central cavity (114; 214; 314; 414) having a leading end (113a; 213;a 313a; 413a) and a trailing end (113b; 213b; 313b; 413b) corresponding to a leading end and a trailing end of the airfoil section, and a tail (118; 218; 318; 418) extending from the baffle wall, the tail including at least one feature configured to disturb an airflow surrounding the tail. A baffle for the airfoil vane assembly and a method of assembling a ceramic matrix composite airfoil vane are also disclosed.
