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

The invention claimed is:

1. A V-band clamp comprising:
a mount plate that includes along an edge thereof a longitudinally extending V-groove and a mount portion at each end of the V-groove, the 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;
a plurality of V-band members each having a longitudinally extending V-groove and a mount portion at each opposing end of each V-groove; and
a plurality of coupling elements configured to couple at least two of the V-band members to each other and at least one of the V-band members to the mount plate, thereby aligning the V-grooves of the V-band members with the V-groove of the mount plate;
wherein at least one of the plurality of coupling elements comprises a latch configured to removably connect at least two adjacent mount portions and to tighten the V-band clamp
wherein the mount plate further includes a clevis configured to couple the V-band clamp to a third component that is physically separate from the V-band clamp and the first and second components.

2. The V-band clamp of claim 1 , wherein the mount plate is articulated to comprise the plurality of V-band members.

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

4. The V-band clamp of claim 1 , wherein the mount plate comprises:
an integral V-band defining the longitudinally extending V-groove; and
a mount surface extending from the integral V-band and configured to at least partially support the first component.

5. The V-band clamp of claim 4 , wherein at least one of the plurality of V-band members is 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.

6. The V-band clamp of claim 4 , 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.

7. The V-band clamp of claim 4 , wherein the mount plate is a load bearing structure.
