A turbine blade having a base and an airfoil, the base including a root end. The airfoil including a skin extending from the base and defining a leading edge, a trailing edge, having a tip end opposite from the root end. The turbine blade further including dividers located within the airfoil. The dividers, leading edge, trailing edge, and skin define serpentine channels within the airfoil. A first multi-bend heat exchange path and a second multi-bend heat exchange path extend through the serpentine channels to cool portion of the turbine blade.

Turbine blade with serpentine channels

A turbine blade having a base and an airfoil, the base including a root end. The airfoil including a skin extending from the base and defining a first edge, a second edge, having a tip end opposite from the root end. The turbine blade further including a base rib extending from the base and into the airfoil, a center divider extending from adjacent the first edge towards the second edge, a center rib disposed between the center divider and the second edge, extending from adjacent the center divider towards the tip end and extending from adjacent the center divider towards the root end, a tip center rib extending from adjacent the second edge towards the first edge, a tip rib extending from adjacent the tip center rib towards the base, a dividing rib and a first channel.

A gas turbine engine preswirler () includes an outer ring () and an inner ring (). The inner ring () includes a plurality of angled holes (). Each angled hole () follows a vector which is angled in at least one plane. A component of the vector is located on a plane perpendicular a radial from an axis of the preswirler (). The component of the angle is angled relative to an axial direction of the preswirler ().

A gas turbine engine turbine diaphragm () includes an inner cylindrical portion (), a mounting portion (), and a disk portion (). The mounting portion () is located radially outward from the inner cylindrical portion (). The disk portion () extends radially between the inner cylindrical portion () and the mounting portion (). The disk portion () includes a plurality of angled holes (). Each angled hole () follows a vector which is angled in at least one plane. A component of the vector is located on a plane perpendicular to a radial extending from an axis of the diaphragm (). The component of the vector is angled relative to an axial direction of the diaphragm ().
