Abstract
Official abstract text for this publication.
A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a fluid injector for a gas turbine engine comprising: depositing material onto a piece of tube stock, the piece of tube stock having a terminal axial end defining an opening of the piece of tube stock; and machining the deposited material into a fluid injector component, wherein the piece of tube stock is a prefilmer, wherein depositing material includes depositing material on the terminal axial end of the piece of tube stock around a full circumference of the terminal axial end such that the deposited material extends axially outward of the terminal axial end and extends radially inward of an inner diameter of the piece of tube stock, and wherein machining includes forming a prefilming surface on an inside portion of the deposited material. 2. The method as recited in claim 1 , wherein machining includes forming the deposited material into a frustoconical surface extending axially outward from the terminal axial end and converging in a direction away from the terminal axial end of the piece of tube stock. 3. The method as recited in claim 1 , wherein depositing material includes depositing material on the terminal axial end such that the deposited material extends radially outward of an outer diameter of the piece of tube stock. 4. The method of claim 1 , wherein the deposited and machined material is coaxial with the piece of tube stock and wherein the inside portion defines an inner diameter at a terminal axial end of the deposited and machined material, the inner diameter smaller than the inner diameter of the piece of tube stock.
