gyro sensor
Description
DUS 1209E pitch-rate sensor is an aviation gyro instrument used in automatic flight control systems installed on Mi-8/Mi-17 series helicopters, including Mi-8T, Mi-8MT, Mi-8AMT, Mi-8MTV-1 and Mi-17. The unit converts angular pitch rate into an electrical output signal used by the AP-34B autopilot to stabilize longitudinal aircraft attitude and damp pitch oscillations.
The sensor supplies continuous feedback into the control system, allowing the autopilot to counteract disturbances, reduce pilot workload and maintain stable pitch behavior during climb, descent, level flight and hover. The device forms part of the vertical dynamic control loop and works jointly with channel amplifiers and executive units.
The DUS-1209E operates from the aircraft’s onboard AC power supply and is designed to function reliably across the full operational flight envelope of the helicopter.
Alternate Designations:
DUS-1209E may also appear as:
DUS1209E, DUS-1209-E, ДУС-1209Е, ДУС1209Е
All designations refer to the same sensor.
