Gas turbine engine having a vane assembly

Abstract

A vane assembly for a gas turbine engine includes an outer platform, an inner platform, a vane, and a seal. The outer platform is disposed proximate a case. The outer platform has a first rail extending towards the case. The first rail has a first face, a second face disposed opposite the first face, and a first opening extending from the first face towards the second face. The inner platform is disposed opposite the outer platform. The vane extends between the inner platform and the outer platform. The seal is received within a slotted region that is disposed between the first face and the second face.

The invention claimed is: 
     
       1. A gas turbine engine, comprising:
 a case; and 
 a vane assembly connected to the case, the vane assembly comprising:
 an outer platform disposed proximate the case, the outer platform having a first rail extending towards the case, the first rail having a first face, a second face disposed opposite the first face, a first opening extending from the first face towards the second face, the first opening includes a first side surface extending from the first face towards a first support surface, a second side surface disposed opposite the first side surface and extending from the first face towards a second support surface, and a first opening surface extending between the first side surface and the second side surface, the first opening surface extending from the first face towards a third support surface extending between the first support surface and the second support surface, the first opening the first opening having a maximum first width measured between first side surface and the second side surface, the first rail having a second opening that includes a third side surface extending from the second face towards a fourth support surface, a fourth side surface extending from the second face towards a fifth support surface, and a second opening surface extending from the second face towards a sixth support surface, the second opening having a maximum second width measured between the third side surface and the fourth side surface that is less than the maximum first width, and a slotted region disposed between the first opening and the second opening. 
 
 
     
     
       2. The gas turbine engine of  claim 1 , further comprising a seal received within the slotted region that is disposed between the first support surface, the second support surface, the third support surface, the fourth support surface, the fifth support surface, and the sixth support surface. 
     
     
       3. The gas turbine engine of  claim 2 , wherein the seal has a seal body extending between a first seal face and a second seal face. 
     
     
       4. The gas turbine engine of  claim 3 , wherein the first seal face engages the first support surface, the second support surface, and the third support surface and the second seal face engages the fourth support surface, the fifth support surface, and the sixth support surface. 
     
     
       5. The gas turbine engine of  claim 1 , wherein the slotted region has a slotted region width that is greater than the first width. 
     
     
       6. The gas turbine engine of  claim 1 , wherein the case includes a mounting feature that extends from the case the mounting feature configured as a rail having a hooked portion. 
     
     
       7. The gas turbine engine of  claim 6 , wherein the first rail has a rail member extending from the first face towards the mounting feature to connect the vane assembly to the case. 
     
     
       8. A vane assembly for a gas turbine engine, the vane assembly comprising:
 an outer platform disposed proximate a case, the outer platform having a first rail extending towards the case, the first rail having a first face, a second face disposed opposite the first face, a first opening extending from the first face towards the second face, a second opening spaced apart from the first opening and extending from the second face towards the first surface, and a slotted region disposed between the first opening and the second opening, the second opening having a maximum second opening width that is less than a maximum first opening width of the first opening; 
 an inner platform disposed opposite the outer platform; 
 a vane extending between the inner platform and the outer platform; and 
 a seal received within the slotted region, the seal having a seal body that extends between a first seal end and a second seal end including a curved portion that curves towards the first face. 
 
     
     
       9. The vane assembly of  claim 8 , wherein the first rail has a first rail member extending from the first face and a second rail member spaced apart from the first rail member extending from the first face. 
     
     
       10. The vane assembly of  claim 9 , wherein the slotted region is disposed between the first rail member and the second rail member.
