Abstract
The invention concerns a method for manufacturing of a gas turbine engine component () comprising an outer ring structure (), an inner ring structure (), and a plurality of circumferentially spaced elements () extending between the inner ring structure () and the outer ring structure (), wherein a primary gas channel for axial gas flow is defined between the elements (), and wherein the component () has an inlet side for gas entrance and an outlet side for gas outflow. The invention is characterized in that the method comprises the step of machining a one-piece metal blank as to form a one-piece part () comprising: a portion () of each of said elements (), wherein said portion () relates to a portion of an extension length of the elements () between said ring structures (); and a ring-shaped member () that connects said element portions () and that is intended to form part of one of the ring structures. The invention also concerns a gas turbine engine () comprising a component () manufactured according to the above method.
