7.7 Airplane control systems
Airplane control systems include control systems for drooping ailerons (flaperons), elevator
with trim tab, rudder and nose wheel, engine and brakes.
The control system is combined consisting of foot- and hand-actuated subsystems.
Ailerons and elevator are hand-actuated and are controlled using yokes. The rudder and
nose wheel control is foot-actuated using pedals.
7.7.1 AFHT control system
The all-flying horizontal tail (AFHT) control system (see
) is combined, it consists of
two
4.0 mm (5/32") cables, passing through a block of pulleys and a fairlead, bellcrank
and pushrod.
“Push” and “pull” forces are applied by the pilot to the yoke (1) is passed via the control
column (2) to the cables (3). Then via the bellcrank (4) located near the frame No.9, the
control forces is passed to the pushrod (5) connected to the AFHT arm (6). The cables
routing is ensured with a block of pulleys (7), located in front of the seat beam and fairlead
(8) on the luggage container wall. The cable tension and AFHT incidence angle adjustment
is ensured using the turnbuckles (9) located forward of the bellcrank (4).
AFHT deflection angles: 15±1° up and 5±1° down.
