Additively manufactured combustor liner v-band cooling ring

A combustor comprising:

• an inner wall circumscribing an axis;
• an outer wall spaced outward relative to the inner wall, wherein the inner wall, the outer wall, or both the inner wall and the outer wall comprising a v-band ring;
• and
• a head wall extending from the inner wall to the outer wall to enclose an upstream end of the combustor;
• wherein the v-band ring comprises:
• a monolithic body extending circumferentially entirely about the axis and extending axially parallel to the axis from a first end to a second end, the monolithic body comprising:
• an outer surface facing away from the axis and extending from the first end to the second end;
• an inner surface facing inward towards the axis and extending from the first end to the second end, wherein the inner surface includes a convergent frustoconical segment, a convex segment, and a divergent frustoconical segment that form a V-shaped cross-section of the monolithic body with a rounded vertex;
• a plurality of scoops extending from and integrally formed with the convex segment of the inner surface;
• and
• a plurality of passages extending through the monolithic body, each passage extending from the outer surface through one of the plurality of scoops;
• wherein the convergent frustoconical segment has a decreasing radial dimension in a direction from the first end towards the convex segment, and
• wherein the divergent frustoconical segment has an increasing radial dimension in a direction from the convex segment towards the second end, and
• wherein at least an oblique scoop of the plurality of scoops includes an oblique passage of the plurality of passages extending tangentially about the axis and axially relative to axis towards the first end of the monolithic body.

A v-band ring for a gas turbine combustor having a circumferentially extending wall, the v-band ring comprising:

• a monolithic body extending circumferentially entirely about an axis and extending axially parallel to the axis from a first end to a second end, the monolithic body comprising:
• an inner surface facing inward towards the axis and extending from the first end to the second end, wherein the inner surface includes, in series, a first frustoconical segment, a convex segment, and a second frustoconical segment that form a V-shaped cross-section of the monolithic body with a rounded vertex;
• a plurality of scoops extending from and integrally formed with the convex segment of the inner surface;
• and
• a plurality of passages extending through the monolithic body, each passage extending through one of the plurality of scoops;
• wherein at least an oblique scoop of the plurality of scoops includes an oblique passage of the plurality of passages extending tangentially about the axis and axially relative to axis towards the first end of the monolithic body.
