US Patent:

6734390, May 11, 2004

Filed:

Mar 24, 2003

Appl. No.:

10/396027

Inventors:

Lowell D. Frye - Chandler AZ

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

B23K 2638

US Classification:

2191217, 21912171

Abstract:

A system and method for trepanning holes into a work piece as relative movement between the work piece and a pulsed laser occurs. As a cylindrical work piece rotates for example, a position controlled pulse laser fires a first series of timed pulses. During each subsequent rotation of said work piece another series of pulses is fired such that the periphery of a row of identical holes is cut into the cylindrical work piece.

International Classification:

B23K 26/38

US Classification:

21912171

Abstract:

Methods are provided of forming a plurality of fan-shaped effusion holes on a combustor having a surface, each hole having an outlet on the combustor surface. The method may include rotating the combustor relative to a laser beam, and positioning the combustor to a first position where the laser beam is at a first predetermined angle relative to the combustor surface. The laser beam is pulsed at the combustor surface to form a first plurality of trepan cuts. The first predetermined angle is adjusted to a second position where the laser beam is at a second predetermined angle relative to the combustor surface. The laser beam is pulsed at each trepan cut of the first plurality of trepan cuts, to thereby form a cut for at least a portion of the fan shape of each effusion hole outlet, wherein each cut overlaps a trepan cut of the first plurality of trepan cuts.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

B23K 26/38

US Classification:

21912171, 21912172

Abstract:

A method of forming a plurality of shaped holes on a workpiece. The method may include rotating the workpiece about multiple axes relative to a laser beam, and positioning the laser at a first predetermined angle relative to the workpiece. The laser beam is pulsed to form a first plurality of trepan cuts defining a row of metering holes. The laser beam, after adjusting to a next predetermined angle and adjacent a previous row of trepan cuts, is pulsed to create a plurality of rows of trepan cuts wherein each cut in the previous row of trepan cuts is connected to a cut in said subsequent row of trepan cuts. The plurality of rows of trepan cuts are formed in a side-to-side sweeping formation and define a portion of each of the shaped holes. Next, the laser is pulsed in alignment with the metering hole to remove debris from therein.

F23M 5/00

US Classification:

60755, 2989002

Abstract:

A combustor is provided for a turbine engine. The combustor includes a first liner having a first hot side and a first cold side; a second liner having a second hot side and a second cold side, the second hot side and the first hot side forming a combustion chamber therebetween. The combustion chamber is configured to receive an air-fuel mixture for combustion therein. The combustor further includes an insert having a body portion extending through the first liner and terminating at a tip, the body portion configured to direct air flow into the combustion chamber. The insert further includes a cooling hole defined in the body portion and configured to direct a first portion of the air flow toward the tip as cooling air.

US Classification:

60754, 2988922, 138103

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.
