Abstract: A variable cross-section tube adapter (VCSTA) is described herein. The VCSTA is configured to decrease bending stresses in high performance oval or circular tubes. Specifically, the VCSTA is configured decrease bending stresses in high performance oval or circular tubes between substantially the end of the tube and the housing and/or base to which the tube is coupled. A variable cross-section double wall tube (VCSDWT) profile is also described herein. For instance, VCSDWT may comprise an integral curved profile (bell shape) portion.

Abstract translation: 本文描述了可变横截面管适配器（VCSTA）。 VCSTA配置为降低高性能椭圆形或圆形管中的弯曲应力。 具体来说，VCSTA被配置为在管子的基本上端部和与管连接的壳体和/或基座之间的高性能椭圆形或圆形管中减小弯曲应力。 本文还描述了可变横截面双壁管（VCSDWT）轮廓。 例如，VCSDWT可以包括整体弯曲轮廓（钟形）部分。
