ABSTRACT:
The structure comprises four groups of elongated rectilinear elements, with the elements of each group parallel to one another. The elements of three of the groups are mutually orthogonal and the elements of the other group are disposed diagonally to the elements of two of the three mutually orthogonal groups. The structure is useful for fabricating nosetips for maneuvering re-entry vehicles.
