7.7.3 Rudder and nose wheel control system
The rudder and nose wheel control system (
) is combined, it consists of pedals, nose
landing gear strut control bellcrank, two pushrods, two
Ø2.5 mm (3/32 in) cables, passing
through two front and two rear pulleys.
Fig. 6. Rudder and nose landing gear control system
The front (right) pedals (1) and rear (left) pedals (2) are fixed with nylon supports to
longitudinal beams of the cockpit floor. The bellcrank (3) attached to the nose landing gear
strut is connected to the pedals with the right (4) and left (5) pushrods. The right (6) and left
(7) cables connect the pedals to the rudder arms. The cable routing is ensured with two
pulleys (8) on the frame No.3 and two pulleys (9) near the frame No.9.
Adjustment of the nose landing gear position is achieved with pedals set to neutral position
using pushrods (4) and (5). The cable tension and adjustment of the rudder position is
achieved using the turnbuckles (11) located near the frame No.9.
In its neutral position the rudder is deflected to the right by the angle of +2.5° (to the right)
for compensation of the engine torque. The rudder deflection angle to each
side is 25±1°.
7.7.4 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 by means of aileron drooping (flap extension) mechanism. The flaperon control
system (
) is combined and, beside the aileron drooping mechanism, it includes two
yokes, control column, two control column pushrods, control column bellcrank, two
Ø2.5 mm
