GD& T for Flexible Contoured Structures 975604

The aerospace industry uses flexible complex contoured structure in aircraft. To take advantage of advancements in engineering design, assembly methods, and inspection tools, the dimensional requirements for this kind of structure can be specified using Geometric Dimensioning and Tolerancing (GD&T) per ASME Y14.5M-1994, “Dimensioning and Tolerancing.” The 1994 revision of this standard includes some new features which can be used to specify the dimensional requirements for flexible complex contoured structure, but there are no examples on how GD&T can or should be applied. This paper gives some examples how GD&T can be applied on flexible complex contoured structure and how this usage specifies the dimensional requirements for such parts.
