Abstract

A V-band clamp includes a V-band segment that has a V-groove and is configured to generally circumscribe a flange of a first component and a flange of a second component. The V-band segment has a coupling element that is configured to couple the V-band clamp to a third component. The V-band clamp also has a latch disposed on the V-band segment that is configured to tighten the V-band clamp about the flanges.

First claim

1 . A V-band clamp comprising:
a V-band segment having a V-groove and configured to generally circumscribe a flange of a first component and a flange of a second component, the V-band segment having a coupling element configured to couple the V-band clamp to a third component; and a latch disposed on the V-band segment configured to tighten the V-band clamp about the flanges.

2 . The V-band clamp of claim 1 , wherein the coupling element comprises a clevis.

3 . The V-band clamp of claim 1 , wherein the coupling element comprises a tab.

4 . The V-band clamp of claim 1 , wherein the V-band segment further comprises:
a mount plate extending from the V-groove configured to at least partially support the first component.

5 . The V-band clamp of claim 4 , wherein the mount plate is articulated to comprise a plurality of V-band segments.

6 . The V-band clamp of claim 1 , wherein the coupling element is disposed at a position of the V-band clamp distal to the latch.

7 . A mount plate comprising:
an integral V-band defining a V-groove configured to receive a first portion of a flange belonging to a first component and a first portion of a flange belonging to a second component; and a mount surface extending from the integral V-band and configured to at least partially support the first component.

8 . The mount plate of claim 7 , wherein the mount plate is a first V-band segment of a V-band clamp.

9 . The mount plate of claim 8 , and further comprising:
a second V-band segment of the V-band clamp, wherein the second segment is attached to the mount plate and configured to be positioned about a second portion of the flange belonging to the first component and a second portion of the flange belonging to the second component.

10 . The mount plate of claim 9 , and further comprising:
a latch for joining adjacent V-band segments.

11 . The mount plate of claim 7 , wherein the first component is a heat exchanger in a gas turbine engine and the second component is an outlet duct in a gas turbine engine.

12 . The mount plate of claim 7 , wherein the mount plate is a load bearing structure.

13 . The mount plate of claim 7 , wherein the mount plate includes a clevis for attaching the mount plate to a gas turbine engine core.

14 . A method for removably securing a first component to a second component, the method comprising:
positioning a first portion of a flange belonging to a first component at least partially within a V-band segment; positioning a first portion of a flange belonging to a second component at least partially within the V-band segment; positioning the V-band segment about a second portion of the flanges belonging to the first and second components, wherein the V-band segment forms a V-band clamp; tightening the V-band clamp; coupling the V-band clamp to a third component.

15 . The method of claim 14 , wherein the first component is a heat exchanger in a gas turbine engine and the second component is an outlet duct in a gas turbine engine.

16 . The method of claim 14 , wherein the third component is a gas turbine engine core.

17 . The method of claim 14 , wherein the V-band clamp is tightened using a latch.

18 . The method of claim 14 , and further comprising:
loosening the V-band clamp; removing the V-band segment from the second portion of the flanges of the components; and removing the first component from the V-band segment.

19 . The method of claim 14 , wherein the V-band segment remains mounted to the third component after the first component is removed.

20 . The method of claim 14 , wherein the first and second components comprise ducts.
