Abstract
A combustor for a turbine engine is provided. The combustor includes a first liner and a second liner forming a combustion chamber with the first liner, the combustion chamber configured to receive an air-fuel mixture for combustion therein. The first liner defining an air admission hole for directing a first jet of pressurized air into the combustion chamber, and the air admission hole may have a non-circular shape. The combustor further includes an insert positioned within the air admission hole to guide the first jet through the air admission hole and into the combustion chamber.

A combustor for a turbine engine, comprising:
- a first liner;
- a second liner forming a combustion chamber with the first liner, the combustion chamber configured to receive an air-fuel mixture for combustion therein;
- the first liner defining an air admission hole for directing a first jet of pressurized air into the combustion chamber, the air admission hole having a non-circular shape;
- and
- an insert positioned within the air admission hole to guide the first jet through the air admission hole and into the combustion chamber.
A method for installing an insert in an air admission hole of a combustor liner, the insert including a body portion, a shoulder, and an inlet portion and the combustor liner having a liner wall with a first side and a second side, the method comprising the steps of:
- inserting the inlet portion through the air admission hole from the first side to the second side until the shoulder abuts the hot side, wherein the air admission hole has a generally non-circular shape;
- and
- deforming the inlet portion such that the inlet portion has an outer diameter greater than a diameter of the air admission hole.
An insert for installation in an air admission hole of a combustor liner wall with a first side and a second side, comprising:
- a tubular body portion, the tubular body portion having a non-circular outer circumference;
- a shoulder circumscribing the tubular body portion;
- and
- a curved inlet portion extending from the tubular body portion.
