## Abstract

A heat shield panel including: a first surface; a second surface opposite the first surface; and a plurality of cooling apertures extending from the first surface to the second surface through the heat shield panel, each of the plurality of cooling apertures are oriented at a non-normal angle relative to the second surface

## Claims

### Claim 1

A heat shield panel for a gas turbine engine, the heat shield panel comprising:
a first surface;
a second surface opposite the first surface; and
a plurality of cooling apertures extending from the first surface to the second surface through the heat shield panel, wherein each of the plurality of cooling apertures are oriented at a non-normal angle relative to the second surface.

### Claim 2 (depends on 1)

The heat shield panel of claim 1, further comprising:
one or more threaded studs extending away from the second surface of the heat shield panel.

### Claim 3 (depends on 1)

The heat shield panel of claim 1, further comprising:
one or more quench holes extending from the first surface to the second surface through the heat shield panel.
