ALDAS STRUCTURE

Elements of the Structure

The structure elements are assumed to be good conductors. One major item of the structure may be a choice of

1. general ellipsoid
2. a cylinder of elliptical cross-section with a choice of half-ellipsoid or truncated cone as nose and tail
3. a cylinder of rectangular cross-section with an optional truncated nose-cone

The rest of the structure is made up from

1. circular cylinders
2. plates each having between 3 and 15 corners
