A Method of Estimating Human Shapes by Fitting the Standard Human Model to Partial Measured Data

An airship envelope manufacturing method uses a braider such that the envelope is formed as one object composed by the braider. A pair of braiding materials, whose braiding angle is ±theta° to the axis, and an axial material whose angle is 0° to the axis, are organized as the braiding layer by the braider BR and the envelope En shaped like the airship is composed as one body by the braiding layer. The thickness of the braiding layer in both of the axial end parts of the airship envelope is arranged to be formed thinner than the thickness in the axial central part. The three braiding layers can be a spindle-shaped tape made of a plurality of parallel fibers having non-identical lengths, and the width of the spindle-shaped tape along the airship axis can be a function of an airship diameter along the airship axis.
