Like
all toroidal surfaces, there are a number of properties which can be
varied to
fine tune the surface to the constraints which can emerge throughout
the design
development. The radii of the curve of the wing ribs were changed a
number of
times in response to the structural demands of the span of the member.
The
radius and the angle of the axis of the toroid was varied in response
to the
changes in the rib profile in order to ensure the intersection along
the
horizontal cut line was within reasonable cantilever limits. The
angular setout
of the structural and cladding modules were varied to limit drift. The
overall
surface is a doubly curved form clad in identical glass and aluminum
panels.
