A preswirler of a gas turbine engine includes an outer ring. The outer ring includes an outer flange with a plurality of first holes, and an outer cylindrical portion extending from the outer flange. The preswirler also includes an inner ring. The inner ring includes an inner flange spaced apart from the outer flange. The inner ring also includes an inner cylindrical portion located within the outer cylindrical portion and a back portion extending from the inner flange to the inner cylindrical portion. The inner ring further includes a plurality of second holes.

Preswirler configured for improved sealing

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 ().
