涡轮叶片附接机构
摘要：
提供了一种用于燃气涡轮发动机(10)的涡轮叶片组件(75)。涡轮转子叶片组件(75)包括涡轮转子叶片(74)和附接销(110)，并且涡轮转子叶片(74)和附接销(110)具有用于提供叶片(74)与销(110)之间的表面界面的特征。具体而言，附接销(110)具有三角形截面形状，并且叶片(74)限定用于收纳附接销(110)的销孔(90)。还提供了一种用于将涡轮转子叶片(74)附接于燃气涡轮发动机(10)的涡轮转子盘(94)的附接销(110)。附接销(110)包括限定至少一个平面表面的本体(112)，并且平面表面提供附接销(110)与涡轮转子叶片(74)之间的面接触界面。
摘要（英）：

A turbine blade assembly (75) for a gas turbine engine (10) is provided. The turbine rotor blade assembly (75) includes a turbine rotor blade (74) and an attachment pin (110), and the turbine rotor blade (74) and attachment pin (110) have features for providing a surface interface between the blade (74) and pin (110). In particular, the attachment pin (110) has a triangular cross-sectional shape, and the blade (74) defines a pin hole (90) for receipt of the attachment pin (110). An attachment pin (110) for attaching a turbine rotor blade (74) to a turbine rotor disk (94) of a gas turbine engine (10) also is provided. The attachment pin (110) includes a body (112) defining at least one planar surface, and the planar surface provides a surface contact interface between the attachment pin (110) and the turbine rotor blade (74).
