Abstract

Official abstract text for this publication.

A gas turbine engine having a pre-swirler adjustability is presented. The pre-swirler includes a pre-swirler insert installed in a component enclosed by a cover. The component includes an inner compressor exit diffusor enclosed by an outer casing or a shaft cover enclosed by the inner compressor exit diffusor. The pre-swirler is adjustable by replacing the pre-swirler insert. An access port including an access window is arranged on the cover. The access port gives access to the pre-swirler insert for replacement through the access window. The access window includes a manhole or combustor assembly installation hole on the outer casing, or a cutout on the inner compressor exit diffusor. The access port allows adjusting the pre-swirler by replacing the pre-swirler insert installed in the component without lifting the cover enclosing the component.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for adjusting a pre-swirler arranged on a component of a gas turbine engine, wherein the pre-swirler comprises a pre-swirler insert installed in the component, wherein the pre-swirler insert is configured to be replaceable for adjustment, the method comprising: arranging an access port including an access window on a cover enclosing the component to give access to the pre-swirler insert installed in the component; and replacing the pre-swirler insert through the access window, wherein the cover comprises an inner compressor exit diffusor, wherein the component comprises a shaft cover, and wherein the access window is arranged by cutting a cutout on the inner compressor exit diffusor, further comprising turning the shaft cover using a clocking tool passing through the access window on the inner compressor exit diffusor for accessing a plurality of pre-swirler inserts through the access window. 2. The method as claimed in claim 1 , further comprising arranging a plurality of access ports on a circumference of the inner compressor exit diffusor for accessing a plurality of pre-swirler inserts respectively. 3. The method as claimed in claim 1 , further comprising replacing a torque pin installed in the inner compressor exit diffusor with a ball pin prior to turning the shaft cover.
