Abstract
A static structure of a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, an outer platform, an inner platform, an airfoil that extends between the outer platform and the inner platform, a service tube disposed at least partially through the airfoil, and a seal assembly that seals between the service tube and one of the outer platform and the inner platform.
Claims11
A static structure of a gas turbine engine, comprising:
- an outer platform;
- an inner platform;
- an airfoil that extends between said outer platform and said inner platform;
- a service tube disposed at least partially through said airfoil and configured to direct airflow radially inwardly to cool or pressurize another component;
- and
- a seal assembly that seals between said service tube and one of said outer platform and said inner platform,
- wherein said service tube includes a tube end fitting that includes a groove, and a seal separate from said seal assembly is positioned within said groove,
- wherein said tube end fitting includes a second groove that receives a locking plate of said seal assembly.
5 more elements
A gas turbine engine, comprising:
- a high pressure turbine;
- a low pressure turbine;
- a mid-turbine frame positioned between said high pressure turbine and said low pressure turbine, wherein said mid-turbine frame includes:
- an outer platform;
- an inner platform;
- an airfoil that extends between said outer platform and said inner platform;
- a service tube extending within said airfoil and including a tube end fitting that includes a first groove and a second groove;
- a seal positioned in said first groove for sealing between said service tube and a neighboring component;
- and
- a locking plate positioned in said second groove for sealing between said service tube and one of said outer platform and said inner platform.
