Abstract
A component for a gas turbine engine may comprise a cooling channel. A first trip strip may extend from a wall of the cooling channel. A leg of the first trip strip and a first plane orthogonal to a direction of airflow through the cooling channel may form a first angle. A second trip strip may be downstream from the first trip strip and extending from the wall of the cooling channel. A leg of the second trip strip and a second plane orthogonal to the direction of airflow through the cooling channel may form a second angle different from the first angle.
Claims25
A component for a gas turbine engine, comprising:
- an internal cooling channel disposed within the component;
- a first trip strip extending from a first wall of the internal cooling channel, the first trip strip comprising a first leg extending in a downstream direction toward a second wall of the internal cooling channel, wherein the first trip strip is located a first distance from an inlet of the internal cooling channel, and wherein the first leg of the first trip strip and a first plane orthogonal to a direction of airflow through the internal cooling channel form a first angle;
- and
- a second trip strip extending from the first wall of the internal cooling channel, the second trip strip comprising a first leg extending in the downstream direction toward the second wall of the internal cooling channel, wherein the second trip strip is located a second distance from the inlet, the second distance being greater than the first distance, and wherein the first leg of the second trip strip and a second plane orthogonal to the direction of airflow through the internal cooling channel form a second angle different from the first angle.
A gas turbine engine, comprising:
- a compressor;
- and
- an internally cooled component aft of the compressor, the internally cooled component comprising:
- a cooling channel,
- a first trip strip extending from a first wall of the cooling channel, wherein a first leg of the first trip strip extends in a downstream direction toward a second wall of the cooling channel, and wherein the first leg of the first trip strip and a first plane generally orthogonal to a direction of airflow through the cooling channel form a first angle, and
- a second trip strip downstream from the first trip strip and extending from the first wall of the cooling channel, wherein a first leg of the second trip strip extends in the downstream direction toward the second wall of the cooling channel, and wherein the first leg of the second trip strip and a second plane orthogonal to the direction of airflow through the cooling channel form a second angle different from the first angle.
An airfoil, comprising:
- an internal cooling channel;
- and
- a turbulator formed in the internal cooling channel, wherein a first portion of the turbulator and a first plane orthogonal to a direction of airflow through the internal cooling channel form a first angle, and wherein a second portion of the turbulator downstream from the first portion and a second plane orthogonal to the direction of airflow through the internal cooling channel form a second angle different from the first angle.
A component for a gas turbine engine, comprising:
- an internal cooling channel disposed within the component;
- a first trip strip extending from a first wall of the internal cooling channel, the first trip strip comprising a first leg and a second leg joined at a first apex, wherein the first leg of the first trip strip and the second leg of the first trip strip form a first angle;
- and
- a second trip strip located downstream of the first trip strip and extending from the first wall of the internal cooling channel, the second trip strip comprising a first leg and a second leg joined at a second apex, wherein the first leg of the second trip strip and the second leg of the second trip strip form a second angle, and wherein the second angle is greater than the first angle.
