есть фото в хорошем разрешении?
вопрос в высокоскоростном элероне (его отсутствии)
есть ли там "таберон" (скоростной элерон внутри закрылка)

и заодно - непонятно кол-во направляющих, зачем столько и так плотно

As another alternative for avoiding the negative impact on cost and weight by the double-slotted flap a ‘taberon’ on the inner flap was studied. The taberon would work as a high-speed roll-control device without compromising the performance of the high-lift wing by avoiding the large spanwise gap in the deployed trailing edge. The need for a best-balanced solution between the disciplines led to a trailing edge solution with a flap three-divided in spanwise direction. Although additional track locations with the resulting fairings and an additional flap-split with the related sealing problems are caused, this solution was still the most beneficial one for the aircraft due to advantages in structural and systems layout – but also due to manufacturability constraints of such large parts. In the evolution of the aircraft layout the high-lift system had to be adapted continuously to the requirements of the actual aircraft performance status. The initial high-lift system design delivered more aerodynamic performance than needed. On one hand this was caused by the change of requirements but on the other hand also from the satisfying performance of the design itself. This allowed several steps of downsizing of the trailing edge system. The flap chord relative to the cruise wing profile chord could be reduced from initial 28% to 24%. At the same time also the shroud position (i.e. spoiler length) could be adapted from 88% to 86%. Also the flap span could be downsized from 73% to 65% of wingspan (figure 12). With this flap span reduction and a corresponding extension of the aileron inwards sufficient roll control efficiency in high-speed flight is maintained. A trailing edge solution with an additional inboard aileron could be avoided
т.е. таберон прикидывали, но оказалось, что такой вариант уже избыточен по подъемной силе, и от него отказались.
Высокоскоростной элерон выкинули вообще и обошлись внешним.
