2.6.4 Control system of flaperons (drooping ailerons)
The airplane is equipped with flaperons (drooping ailerons), which serve as both ailerons
and flaps . The flaperon control system ensures independent function of flaperons as
ailerons and flaps using a differential mechanism.
Fig. 6. Control system of flaperons
(drooping ailerons)
The control force in roll (Fig. 6) applied by the pilot to the control stick 1 is passed to the
central control shaft 2. Then from the bellcrank 9 attached to the shaft it is passed via the
pushrods 7 to the flaperon control shafts 6. The shafts are attached via a Cardan
joint 5 to
the bracket at the root end rib of the flaperon 4 at one end and to the trunnion on the
levers 3 of the flap control mechanism at the other . Stop 8 limits the rotation angle of
bellcrank 9 on the central control shaft and, therefore, angles of yoke rotation and aileron
deflection
Deflection angles of the flaperons (as ailerons): up-19±1°, down -13±1 ° .
