Sketch of the Transverse Airform

A sketch based on the Transverse Airform membrane pattern for Drummond, Oklahoma. It seems simple to lay the gore pattern sideways, but the fabric stretches more across the width (fill) of the fabric than the length (warp). The pattern is “pre-shrunk"—more across the width, less down the length—so when it inflates, it stretches to the proper shape.
