Internal cooling cavity with trip strips

A cooling system, comprising:

• an impingement chamber;
• a first trip strip disposed on a first surface of the impingement chamber, wherein the first trip strip has a first geometry selected from a group consisting of at least one of:
• a v-shaped geometry having a point of the v-shaped geometry oriented relatively downward along an axial extent of the impingement chamber away from an end of the impingement chamber, a circular geometry, a wave geometry, an annular elliptical geometry, or a linear geometry non-parallel and non-orthogonal to the axial extent of the impingement chamber;
• and
• a second trip strip disposed on a second surface of the impingement chamber, wherein the second trip strip has a second geometry selected from a group consisting of at least one of:
• the v-shaped geometry having the point of the v-shaped geometry oriented relatively downward along the axial extent of the impingement chamber away from the end, the circular geometry, the wave geometry, the annular elliptical geometry, or the linear geometry non-parallel and non-orthogonal to the axial extent of the impingement chamber, wherein the first geometry and the second geometry are different,
• wherein the impingement chamber further comprises a cross over channel in fluid communication with the impingement chamber, wherein the channel is oriented at an angle relative to the first surface and is configured to direct a coolant as a jet towards a suction-side surface of the impingement chamber.

An internally cooled engine part, comprising:

• an internal cavity;
• a cross over in fluid communication with the internal cavity;
• an impingement chamber in fluid communication with the cross over, wherein the cross over is configured to direct air towards a suction-side surface of the impingement chamber as a jet;
• a first trip strip disposed on the suction-side surface of the impingement chamber, wherein the first trip strip has a first geometry selected from a group consisting of at least one of:
• a v-shaped geometry having a point of the v-shaped geometry oriented relatively downward along an axial extent of the impingement chamber away from the a tip of the engine part, a circular geometry, a wave geometry, an annular elliptical geometry, or linear geometry non-parallel and non-orthogonal to the axial extent of the impingement chamber, wherein the first trip strip is configured to direct the air impinging on the suction-side surface across the suction-side surface of the impingement chamber;
• and
• a second trip strip disposed on a pressure-side surface of the impingement chamber, wherein the second trip strip has a second geometry selected from a group consisting of at least one of:
• the v-shaped geometry having the point of the v-shaped geometry oriented relatively downward along the axial extent of the impingement chamber away from the tip, the circular geometry, the wave geometry, the annular elliptical geometry, or the linear geometry non-parallel and non-orthogonal to the axial extent of the impingement chamber, wherein the first geometry and the second geometry are different.
