Description
AP-34B Series 2
The AP-34B Series 2 is a four-channel electro-hydraulic automatic flight control system used on Mi-8/Mi-17 helicopter variants (Mi-8T, Mi-8MT, Mi-8AMT, Mi-8MTV-1 and Mi-17). The system enhances helicopter controllability and reduces pilot workload by automatically stabilizing pitch, roll, heading, altitude and airspeed (through pitch).

Operational Principles of AP-34B Series 2
AP-34B operates as a closed-loop stabilizing system across all primary flight regimes, including hover, climb, descent, transitions and level flight. Each channel processes data from aircraft motion sensors and generates control inputs to hydraulic servo actuators, ensuring damping, attitude stabilization and flight path maintenance.

The complete AP-34B Series 2 includes nine modules working jointly within the control loop:
-
Control panel – 6С2.390.007-3
-
Control unit – 6С2.399.000
-
Compensation sensor – 6С2.553.002
-
Roll rate sensor – DUS-1209G
-
Pitch rate sensor – DUS-1209E
-
Yaw rate sensor – DUS-1209K
-
Navigation-pilot amplifier block – BU-NPP-V (1479-V)
-
Zero indicator – IN-4
-
Altitude corrector – KV-11

Flight Safety and Control Limits
These blocks form a closed control loop “helicopter ↔ autopilot ↔ pilot”. The pilot can override the AP-34B Series 2 system at any time, and actuator authority is mechanically limited to approximately 20% of full control travel for flight safety.
