Cooling hole for a gas turbine engine component

A component for a gas turbine engine, comprising:

• a wall having an internal surface and an outer skin;
• a cooling hole having an inlet extending from said internal surface and merging into a metering section, and a diffusion section downstream of said metering section that extends to an outlet located at said outer skin;
• and
• wherein each of said metering section and said diffusion section includes a downstream surface, said downstream surface of said diffusion section is coaxial with said downstream surface of said metering section, and said diffusion section includes a diffusion section inlet and a diffusion section outlet downstream of said diffusion section inlet, said diffusion section outlet includes a leading edge and a trailing edge, and said trailing edge is generally linear and defines the downstream most end across an entire width of said cooling hole, and said trailing edge is defined where said downstream surface meets said outer skin.

A component for a gas turbine engine, comprising:

• a wall having an internal surface and an outer skin;
• a cavity, wherein the internal surface faces into the cavity;
• a cooling hole having an inlet extending from said internal surface and merging into a metering section, and a diffusion section downstream of said metering section that extends to an outlet located at said outer skin;
• and
• wherein said diffusion section of said cooling hole includes a first side diffusion angle, a second side diffusion angle, and a downstream diffusion angle at a downstream surface of said diffusion section, said first side diffusion angle is a different angle from said second side diffusion angle, said downstream diffusion angle is 0° from an axis of said metering section, said downstream surface of said diffusion section is coaxial with a downstream surface of said metering section, said diffusion section does not diffuse toward a downstream edge of said wall, and said diffusion section includes a diffusion section inlet and a diffusion section outlet downstream of said diffusion section inlet, said diffusion section outlet includes a leading edge and a trailing edge, and said trailing edge is generally linear and defines the downstream most end across an entire width of said cooling hole, and said trailing edge is defined where said downstream surface meets said outer skin.
