Synchronizing ring surge bumper

1. A synchronizing ring assembly, comprising:

a synchronizing ring portion that has a first distal end and a second distal end, the first distal end and the second distal end each form an integrated surge bumper, wherein the synchronizing ring portion defines a first height throughout a span of the synchronizing ring portion, the first height increases to a second height at the first distal end and the second distal end of the synchronizing ring portion; and

a bumper assembly mounted to the synchronizing ring portion, a build gap of the integrated surge bumper with respect to an outer surface of an outer case is 4-5 times a build gap of the bumper assembly with respect to the outer surface of the outer case.

2. The assembly as recited in claim 1 , further comprising a ramp between the first height and the second height.

3. The assembly as recited in claim 1 , wherein the synchronizing ring portion is of a 180 degree arc length.

4. The assembly as recited in claim 1 , wherein each integrated surge bumper is of an arc length that is 2-5% that of the synchronizing ring portion.

5. The assembly as recited in claim 1 , wherein a minimum gap of the integrated surge bumper with respect to the outer surface of the outer case is 15-17 times that of a minimum gap of the bumper assembly with respect to the outer surface of the outer case.

6. The assembly as recited in claim 1 , wherein each integrated surge bumper includes a clevis bridge bracket attachment passage.

7. The assembly as recited in claim 6 , wherein the clevis bridge bracket attachment passage is fastened to the synchronizing ring portion.

8. A synchronizing ring assembly, comprising:

a first synchronizing ring portion that has a first distal end and a second distal end, the first distal end and the second distal end each form an integrated surge bumper;

a second synchronizing ring portion that has a first distal end and a second distal end, the first distal end and the second distal end each form an integrated surge bumper;

a first clevis bridge bracket fastened to the first synchronizing ring portion and the second synchronizing ring portion;

a second clevis bridge bracket fastened to the first synchronizing ring portion and the second synchronizing ring portion; and

a multiple of bumper assemblies fastened to the first synchronizing ring portion and the second synchronizing ring portion, a build gap of the integrated surge bumpers with respect to an outer surface of an outer case is 4-5 times a build gap of each of the multiple of bumper assemblies with respect to the outer surface of the outer case.

9. The assembly as recited in claim 8 , wherein the first and second synchronizing ring portion each defines a first height throughout a span and a second height at the first and second distal end to form the integrated surge bumper, each integrated surge bumper includes a clevis bridge bracket attachment passage.

10. The assembly as recited in claim 9 , wherein each integrated surge bumper provides a build gap greater than a minimum gap with respect to the outer surface of the outer case.

11. The assembly as recited in claim 9 , wherein a minimum gap of the integrated surge bumper with respect to the outer surface of the outer case is 15-17 times that of a minimum gap of the bumper assembly with respect to the outer surface of the outer case.

12. The assembly as recited in claim 8 , wherein a minimum gap of the integrated surge bumper with respect to the outer surface of the outer case is 15-17 times that of a minimum gap of the bumper assembly with respect to the outer surface of the outer case.

13. A method of controlling a deflection of a synchronizing ring assembly during a surge event in a gas turbine engine, comprising:

providing a build gap with respect to an outer surface of an outer engine case for an integrated surge bumper at each distal end of a synchronization ring portion a build gap with respect to the outer surface of the outer case is 4-5 times that of a bumper assembly attached to the synchronization ring portion; and

providing a minimum gap with respect to the outer surface of the outer engine case for the integrated surge bumper at each distal end of the synchronization ring portion that is 15-17 times that of a minimum gap of a bumper assembly attached to the synchronization ring portion with respect to the outer surface of the outer case.

14. The method as recited in claim 13 , further comprising providing a rotational input to the synchronizing ring assembly through a clevis bridge bracket fastened to the synchronizing ring portion.
