Core assemblies and gas turbine engine components formed therefrom

A component for a gas turbine engine comprising:

• a cavity formed inside the component and defining a cooling flow path within the component;
• a first cooling circuit fluidly connecting the cavity to an exterior of the component, wherein the first cooling circuit comprises a first portion and a second portion wherein the first portion of the cooling circuit and the second portion of the cooling circuit are configured to define a first exit and a second exit at two different locations on the exterior of the component, and wherein the first portion and the second portion extend from a trunk portion of the first cooling circuit;
• and
• a second cooling circuit formed within the component and merging with the first cooling circuit proximate the first exit of the first cooling circuit,
• wherein the second cooling circuit is fluidly connected to a second cavity different from the cavity the first cooling circuit is fluidly connected to.

A method of forming a core for a component of a gas turbine engine, the method comprising:

• forming a core assembly having a first core body with a trunk that attaches to a cavity core structure, a first branch extending from the trunk and configured to form a first portion of a first cooling circuit in the component, and a second branch extending from the trunk and configured to form a second portion of the first cooling circuit in the component, the first branch of the first core body having a first joining surface;
• attaching a second core body to the first core body at the first joining surface to form a junction, the second core body configured to define a second cooling circuit within the component;
• and
• attaching the first core body to a cavity core structure,
• wherein the junction of the first core body and the second core body define a merging of the first and second cooling circuits proximate an end of the component;
• and
• attaching the second core body to a different cavity core structure than the cavity core structure the first core body is attached to.
