Zusammenfassung:	PROBLEM TO BE SOLVED: To provide systems and methods for reducing stress in vane shroud assemblies by defining a gap between adjacent portions of an airfoil and a shroud, thereby relieving stress from the securing force in a portion of the shroud.SOLUTION: 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.SELECTED DRAWING: Figure 1 【課題】エーロフォイルとシュラウドとの隣接部分の間のギャップを画定することによってベーンシュラウド組立体内の応力を低減し、それによって固定力からの応力は、シュラウドの一部分内で解放されるシステムおよび方法を提供する。【解決手段】エーロフォイルは、接触面およびほぞを含む遠位端を備える。シュラウドは、エーロフォイルとの接触面を備え、ほぞを収容する。取付デバイスは、エーロフォイルとシュラウド接触面との間の固定力を、シュラウドを介して提供し、ギャップは、シュラウド上の応力を低減するために働く。【選択図】図１
