A heat exchanger including an internal passage extending from a first inlet end to a first outlet end; a first longitudinal length extending from the first inlet end to the first outlet end; an inner surface of the passage including a first augmentation feature disposed along the first longitudinal length across the inner surface; an outer surface extending from a second inlet end to a second outlet end, the outer surface being in heat transfer communication with the inner surface; and a first region including portions of both the inner surface and the outer surface adjacent at least a portion of the first inlet end, wherein the first augmentation feature varies a cross-sectional area in a direction along the first longitudinal length and within the first region.

Variable passages to optimize delta p and heat transfer along flow path

A vane ring for a gas turbine engine includes a multiple of vanes that extend between the inner vane platform and the outer vane platform, each of the multiple of vanes contains an airfoil cooling circuit that receives cooling airflow through a respective one of a multiple of feed passages; a multiple of metering passages in the outer vane platform, each of the multiple of metering passages in communication with the respective one of the multiple of feed passages; and a multiple of secondary passages in the outer vane platform, each of the multiple of secondary passages in communication with the respective one of the multiple of metering passages.

Redundant entry cooling air feed hole blockage preventer for a gas turbine engine

A vane ring for a gas turbine engine component includes a multiple of vanes that extend between an inner vane platform and an outer vane platform, each of the multiple of vanes contains an airfoil cooling circuit that receives cooing airflow through a feed passage located in the outer vane platform and an extension from the outer vane platform, the extension comprises a metering passage in communication with the feed passage.

Shape recessed surface cooling air feed hole blockage preventer for a gas turbine engine

A turbine airfoil includes a body that has inner and outer platforms and an airfoil section that extends between the inner and outer platforms. There are film cooling holes that define external breakout points from the body. The external breakout points are located in accordance with Cartesian coordinates of at least points 222 through 256 set forth in Table 1 herein.
