Patent number: 5755093Abstract: The exhaust in a gas turbine engine is lined with stacks of hollow cooling blocks made of a composite material. Air is pumped into each stack and escapes into the exhaust flow from a slot between the blocks in each stack. In addition, the blocks contain passages so that some of the airflow escapes to a space between the stacks. The blocks are attached using special fasteners that does not create mechanical stresses on the composite material.Type: GrantFiled: May 1, 1995Date of Patent: May 26, 1998Assignee: United Technologies CorporationInventors: Mark E.
