Abstract
A load patch for attaching concentrated loads to a flexible inflated structure such as a high-altitude airship is stiff in the direction of the applied load so as to carry the load, and is attached to the inflated structure for a very short distance through T-tape so as to minimize strain concentration in the inflated structure due to the stretching of the inflated structure. Since the load patch must be attached for a long length transverse to the load to distribute the applied load, it is transversely compliant to minimize strain concentration in the inflated structure due to stretching of the inflated structure.
