用于减小静叶护罩组件中的应力的系统和方法
摘要：
本公开提供了用于减小静叶护罩组件中的应力的系统和方法。所述系统和方法通过限定在翼型件和护罩的相邻部分之间的间隙而减小应力，使得来自固定力的应力在护罩的一部分中被减小。翼型件具有带有接触表面和榫头的远端。护罩具有与翼型件的接触表面并且容纳榫头。附接装置通过护罩在翼型件和护罩接触表面之间提供固定力，并且间隙用来减小护罩上的应力。
摘要（英）：

This disclosure provides systems and methods for reducing stress in vane shroud assemblies. The systems and the methods reduce the stress by defining a gap between adjacent portions of an airfoil anda shroud whereby stress from the securing force is relieved in a portion of the shroud. The airfoil has a distal end with a contact surface and a tenon. The shroud has a contact surface with the airfoil and accommodates the tenon. An attachment device provides the securing force between the airfoil and shroud contact surfaces through the shroud and the gap serves to reduce stress on the shroud.
