Abstract
A structure obtained by laying filaments on a convex axisymmetric surface to provide a hemispherical surface. The structure may include with a circular hole or a dead zone centered on an axis of the surface and may be formed by laying filaments along a geodesic path. The structure includes a first and second part, in which the first part includes the axis. The geodesic path formed by the filaments on the first part may be spaced a predetermined distance the opening or circular dead zone.
