Abstract
Official abstract text for this publication.
A duct arrangement may comprise a duct extending along a centerline axis, a flange coupled to an end of the duct, and a balking feature coupled to a distal surface of the duct and extending axially towards the flange, wherein the balking feature is configured to align a clamp with the flange.
First claim
Opening claim text (preview).
What is claimed is: 1. A duct arrangement, comprising: a duct extending along a centerline axis; a flange coupled to an end of the duct; and a balking feature coupled to a distal surface of the duct, wherein the balking feature is configured to align a annular clamp with the flange; the balking feature extends axially towards the flange from the duct when the annular clamp is in an installed position; and a free end of the balking feature is configured to be spaced apart from the annular clamp and a latch of the clamp and spaced apart from the duct when the annular clamp is in the installed position, and the free end of the balking feature is located radially between the latch and the flange. 2. The duct arrangement of claim 1 , wherein the balking feature physically interferes with the annular clamp in response to the annular clamp being misaligned with the flange. 3. The duct arrangement of claim 1 , further comprising a doubler patch coupled between the distal surface of the duct and the balking feature. 4. The duct arrangement of claim 3 , wherein the doubler patch is welded to the distal surface of the duct and the balking feature is welded to the doubler patch. 5. The duct arrangement of claim 1 , wherein the balking feature is welded to the distal surface of the duct. 6. The duct arrangement of claim 1 , wherein the balking feature comprises a piece of sheet metal. 7. The duct arrangement of claim 1 , wherein the balking feature is flexible in a radial direction. 8. The duct arrangement of claim 1 , wherein the balking feature is flexible in a circumferential direction. 9. The duct arrangement of claim 1 , wherein the balking feature is tapered. 10. A duct arrangement, comprising: a first duct comprising a first flange; a second duct comprising a second flange; a clamp circumferentially surrounding the first flange and the second flange, wherein the clamp comprises a first segment and a second segment; a balking feature coupled to the first duct and extending from the first duct into a gap between the first segment and the second segment when the clamp is in an installed position, wherein the balking feature prevents the clamp from being installed over the first flange and the second flange unless the gap is aligned with the balking feature, and the balking feature comprises: a base portion fixed to the first duct, and an axially extending portion extending from the base portion, wherein a free end of the axially extending portion is disposed radially between the clamp and the first duct. 11. The duct arrangement of claim 10 , wherein the first segment is hinged. 12. The duct arrangement of claim 10 , wherein the second segment is hinged. 13. The duct arrangement of claim 10 , wherein the balking feature comprises a piece of sheet metal. 14. The duct arrangement of claim 10 , wherein the balking feature is flexible in a radial direction. 15. The duct arrangement of claim 10 , wherein the balking feature is flexible in a circumferential direction. 16. The duct arrangement of claim 10 , wherein the clamp comprises a V-band clamp. 17. The duct arrangement of claim 10 , wherein the first flange is compressed against the second flanged in response to the clamp being tightened. 18. The duct arrangement of claim 10 , wherein the balking feature is located at a latch side of the clamp.
