| The
photograph shows the central drive unit (consisting of
the two motors and the main gear box) and the four
actuators.
Not shown are the flexible
shafts (several meters long) between the main gear box
and the actuators.
Because the landing flap
panels have a trapezoidal shape and the Fowler travel is
longer on the inboard, a special link between the spindle
nut and the panel is used for compensation. By the use of
slightly longer spindles the other parts could remain
identical. Only the left-hand and right-hand style of the
actuator housing was necessary.
