Abstract

The present application provides a gas turbine engine. The gas turbine engine may include a compressor and an inlet air system positioned upstream of the compressor. The inlet air system may include a wetted media pad for evaporative cooling. The wetted media pad may include a contoured configuration.

First claim

We claim:

1. A gas turbine engine, comprising:
a compressor; and
an inlet air system positioned upstream of the compressor;
the inlet air system comprising a wetted media pad for evaporative cooling;
wherein the wetted media pad comprises a contoured configuration;
wherein the contoured configuration comprises a curved configuration extending from an upper section to a lower section along at least one of a leading edge and a trailing edge.

2. The gas turbine engine of claim 1 , wherein the wetted media pad comprises polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), nylon, polyester, polypropylene, or cellulose.

3. A gas turbine engine of claim 1 , comprising:
a compressor; and
an inlet air system positioned upstream of the compressor;
the inlet air system comprising a wetted media pad for evaporative cooling;
wherein the wetted media pad comprises a plurality of channels therethrough with a branched configuration;
wherein the branched configuration comprises at least one of a larger, single channel branching into smaller, multiple channels and smaller, multiple channels merging into a larger, single channel.

4. The gas turbine engine of claim 3 , wherein the plurality of channels with the branched configuration extend from a leading edge to a trailing edge or from a top edge to a bottom edge.

5. The gas turbine engine of claim 1 , wherein the wetted media pad comprises:
a first media sheet;
the first media sheet comprising a chevron corrugated surface; and
a second media sheet;
the second media sheet comprising a wavy corrugated surface.

6. The gas turbine engine of claim 5 , wherein the chevron corrugated surface and the wavy corrugated surface extend from a leading edge towards a trailing edge and wherein the leading edge and the trailing edge comprise a diamond like shape.

7. The gas turbine engine of claim 6 , wherein the diamond like shape comprises a bonding portion and an expanded portion.

8. The gas turbine engine of claim 5 , wherein the chevron corrugated surface comprises a plurality of chevron channels with diagonally rising portions and diagonally lowering portions.

9. The gas turbine engine of claim 5 , wherein the wavy corrugated surface comprises a plurality of wavy channels with peaks and valleys.

10. A gas turbine engine, comprising:
a compressor; and
an inlet air system positioned upstream of the compressor;
the inlet air system comprising a wetted media pad for evaporative cooling;
wherein the wetted media pad comprises curved configuration;
wherein the curved configuration extends from an upper section to a lower section along at least one of a leading edge and a trailing edge.

11. The gas turbine engine of claim 10 , wherein the wetted media pad comprise polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), nylon, polyester, polypropylene, or cellulose.
