gyro sensor
Description
The DUS 1209K yaw-rate sensor is a precision gyro instrument used as part of the AP-34B automatic flight control system installed on Mi-8/Mi-17 series helicopters, including Mi-8T, Mi-8MT, Mi-8AMT, Mi-8MTV-1 and Mi-17.
The sensor converts the angular rate around the yaw axis (heading change rate) into an proportional electrical signal, enabling the autopilot to stabilize directional attitude, damp turn-induced oscillations and maintain coordinated directional control.
The sensor delivers continuous feedback into the yaw channel of the autopilot, supporting automatic correction during climb, descent, cruise, hover and coordinated maneuvering.
DUС-1209K improves flight stability, reduces pilot workload and enhances handling smoothness during uncommanded yaw disturbances or wind drift.
The unit operates from the aircraft’s onboard AC power supply and is suitable for installation in avionics bays across the full environmental range of Mi-8-class helicopters.
Alternate Designations:
DUS-1209K may also appear as:
DUS1209K, DUS-1209-K, ДУС-1209К, ДУС1209К
All refer to the same component.
