    • The invention concerns a method for manufacturing of a gas turbine engine component (37) comprising an outer ring structure (42, 47), an inner ring structure (41), and a plurality of circumferentially spaced elements (46, 46a, 46b) extending between the inner ring structure (41) and the outer ring structure (42), wherein a primary gas channel for axial gas flow is defined between the elements (46, 46a, 46b), and wherein the component (37) 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 (47) comprising: a portion (46b) of each of said elements (46), wherein said portion (46b) relates to a portion of an extension length of the elements (46) between said ring structures (41, 42); and a ring-shaped member (42) that connects said element portions (46b) and that is intended to form part of one of the ring structures. The invention also concerns a gas turbine engine (1) comprising a component (37) manufactured according to the above method.
    • 本发明涉及一种用于制造燃气涡轮发动机部件(37)的方法,该燃气涡轮发动机部件(37)包括外环结构(42,47),内环结构(41)和多个周向间隔开的元件(46,46a,46b) 在内环结构(41)和外环结构(42)之间,其中在所述元件(46,46a,46b)之间限定用于轴向气流的主气体通道,并且其中所述部件(37)具有入口侧 用于气体入口和用于气体流出的出口侧。 本发明的特征在于,该方法包括加工一体式金属坯件以形成一件式部件(47)的步骤,包括:每个所述元件(46)的部分(46b),其中所述部分 46b)涉及所述环形结构(41,42)之间的元件(46)的延伸长度的一部分; 以及连接所述元件部分(46b)并且旨在形成所述环形结构中的一个的一部分的环形构件(42)。 本发明还涉及包括根据上述方法制造的部件(37)的燃气涡轮发动机(1)。
