Abstract
A combustor includes a shell that at least partially defines a combustion chamber and a grommet mounted in the shell. The grommet has a body that defines a passage through the grommet that is operable to communicate air from outside the combustion chamber into the combustion chamber. The body carries a first surface, an opposite, second surface and a third surface that defines the passage and joins the first surface and the second surface. The third surface includes a bevel surface with respect to at least one of the first surface and the second surface.
Claims16
A combustor comprising:
- a shell at least partially defining a combustion chamber;
- and
- a grommet mounted in the shell, the grommet having a body defining a passage through the grommet that is operable to communicate air from outside the combustion chamber into the combustion chamber, the body carrying a first surface, an opposite, second surface and a third surface defining the passage and joining the first surface and the second surface, the third surface including a bevel surface with respect to at least one of the first surface and the second surface.
A turbine engine comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor,
- the combustor including:
- a shell at least partially defining a combustion chamber, and
- a grommet mounted in the shell, the grommet having a body defining a passage through the grommet that is operable to communicate air from outside the combustion chamber into the combustion chamber, the body carrying a first surface, an opposite, second surface and a third surface defining the passage and joining the first surface and the second surface, the third surface including a bevel surface with respect to at least one of the first surface and the second surface.
A method of controlling quench flow into a combustor, the method comprising:
- providing a shell at least partially defining a combustion chamber and a grommet mounted in the shell, the grommet having a body defining a passage through the grommet that is operable to communicate air from outside the combustion chamber into the combustion chamber, the body carrying a first surface, an opposite, second surface and a third surface defining the passage and joining the first surface and the second surface;
- providing the third surface with a bevel with respect to at least one of the first surface and the second surface, the bevel defining a bevel size;
- and
- selecting the bevel size to reduce variation in a coefficient of discharge of flow of the air through the passage.
