Figure 48: ARRAY 2004 Geometric Data for V-DOSC
The Nominal Vertical Coverage Angle of the array is calculated as the sum of the entered inter-
enclosure angles. This coverage becomes effective at F
1
and for all frequencies higher than F
1
, the
vertical coverage angle is less than this nominal vertical coverage angle. Above F
2
, the vertical coverage
angle perfectly matches the nominal value. Some beaming (vertical coverage narrowing) may occur at
F
3
, especially when the array is of constant curvature type. Further theoretical details related to the
calculation of F
1
, F
2
and F
3
are given in Appendix 6.
Finally, MECHANICAL DATA gives an estimate as to the rear versus front motor and rear rotating leg
versus BUMP angle strap load distribution. These load distributions depend on the size and shape of
the array as well as the array site angle (equal to Site #1) which, in turn, affect the location of the
centre of gravity.
