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.

A profiled element ( ) includes a tubular blank ( ) which is formed into the desired shape by hydroforming. In conjunction with hydroforming, at least one slot essentially in the longitudinal direction of the blank is made in wall portions ( ) on the blank, and a reinforcing element ( ) is fixed in each slot. In a suitable embodiment, each reinforcing element is fixed in two opposite slots and extends through a cavity in the blank. The invention relates to on the one hand a profiled element and on the other hand a method of producing the same.

In a fuel system of a vehicle a filler end of a fuel pipe is attached to the bodywork of the vehicle and accessible via filler opening in the side of the bodywork. The filler end is fastened to a bodywork element situated inside the side of the bodywork, which bodywork element supports a shield arranged around the filler end, which shield finishes at a certain distance from the side of the bodywork and during collisions protects a filler cap mounted on the fuel pipe.
