    摘要: A gas turbine engine component includes a ring element and a plurality of circumferentially spaced load carrying vanes extending in a radial direction of the ring element. At least one of the vanes is made of a composite material. The at least one composite vane is fastened to the ring element. The component further includes first and second wall portions that are fixed in relation to the ring element and arranged on opposite sides of the composite vane. At least a first hole extends through the first wall portion, the composite vane and the second wall portion. The first hole is adapted to receive a first insertion member. The component is arranged such as to, with regard to the first hole, provide a tight fit for the first insertion member in the first wall portion as well as in the composite vane and to provide a loose fit with a radial play in the second wall portion.

    摘要: A method for joining two structural elements by welding, in particular by butt welding comprises forming a weld line joining the two structural elements; and adding material across the weld line, thereby forming one or more crack stoppers for limiting crack propagation along the weld line. The one or more crack stoppers each have a limited extension along the weld line as seen in relation to a length of the weld line. A structural system comprising two structural elements joined by the method is disclosed. The method may be applied, e.g., to components of aircraft engines.

    摘要翻译: 公开了通过焊接,特别是通过对焊来连接两个结构元件46,48的方法。 该方法包括以下步骤: - 形成连接两个结构元件的焊接线30; - 在焊接线上添加材料34,由此形成一个或多个限制沿着焊接线的裂纹传播的限位器。 如相对于焊接线的长度所看到的,一个或多个防裂塞各自沿着焊接线具有有限的延伸。 在另一方面,通过在主要焊接线30上形成一个或多个次要焊缝来形成防裂塞34.可以通过金属沉积来形成次要焊接部34。 优选设置多个裂缝限制器或次级焊缝34,其可以规则地或不规则地彼此间隔开(参见图3B,3C)。 防裂塞或第二焊缝34优选是细长的,例如, 基本上为矩形,椭圆形或椭圆形,尽管圆形也是可能的,并且它们可以垂直地或倾斜地延伸穿过主要焊接线30,或者部分地沿着其长度(70,图5)延伸。 还公开了包括通过该方法连接的两个结构元件的结构系统。 特别地,该方法可以应用于飞机发动机的部件。
