Gas turbine exhaust nozzle noise abatement

An exhaust nozzle for a gas turbine engine. The exhaust nozzle includes a nozzle body having an upstream end axially spaced from a downstream end relative to an axial centerline of the nozzle body and a plurality of V-shaped patterns circumferentially spaced and extending downstream from the downstream end. Each V-pattern includes an inner wall radially spaced from the outer wall, a root, and a tip axially spaced from the root. At least one V-pattern of the plurality of V-patterns includes a first section extending axially downstream from the root, a second section extending axially downstream from the first section, and a third section extending axially downstream from the second section to the tip. The inner wall extends along the first section, the second section, and the third section. The first segment is distinguishable from the second segment, and the second segment is distinguishable from the third segment. 一种用于燃气涡轮发动机的排气喷嘴。排气喷嘴包括喷嘴本体，喷嘴本体具有上游端和多个V形图案，上游端相对于喷嘴本体的轴向中心线与下游端轴向间隔开，多个V形图案周向间隔开并从下游端向下游延伸。每个
