Angular Rate Sensor Set
Description
DUS-1209G/E/K angular rate sensor set
The DUS-1209G/E/K set contains three gyroscopic angular rate sensors for AP-34B autopilot channels. DUS-1209G measures roll rate, DUS-1209E measures pitch rate and DUS-1209K measures yaw or heading rate. Each unit has a separate channel function, while the three devices together provide three-axis angular-rate feedback.
The DUS-1209G/E/K set comprises three functionally connected but individually identified sensors. Suffixes G, E and K define the autopilot channel and must be retained in the marking, inquiry and documentation. Supply of one sensor is not supply of the complete set; the actual delivery scope must be agreed separately and confirmed by an itemised list.
Function in the AP-34B autopilot
Electrical outputs proportional to helicopter angular rate are passed to compatible amplifiers and autopilot control equipment. The system uses these signals for oscillation damping and stabilisation in roll, pitch and heading. The three channel sensors must not be presented as interchangeable merely because their housings are similar.
In the closed autopilot loop, each sensor supplies feedback for its own axis. The signal passes through compatible conditioning equipment to the control channel, where it supports damping and stabilisation. A fault may be in the sensor, amplifier, wiring, supply or actuator path, so troubleshooting must cover the complete AP-34B channel.
Mi-8 and Mi-17 helicopter installation
Operating documentation identifies the 1209G, 1209E and 1209K set in the AP-34B system used by the Mi-8 helicopter family. Roll and heading sensors are installed on the right equipment rack in the crew compartment, while the pitch sensor is located in the radio compartment. Exact positions depend on helicopter modification.
The mounting positions and orientation of the three sensors are different. Replacement requires verification of the suffix, sensitive axis, connector, base and location against the diagram for the individual helicopter modification. Moving sensors between channels because the housings look similar is not permitted unless the approved maintenance documentation explicitly authorises it.
Supply and technical inspection
Retained product data specify a 36–40.5 V, 400 ±8 Hz supply and current consumption up to 0.5 A per sensor. Maintenance includes verification of the channel suffix, mounting, connector, housing condition and passport limits. Testing is performed with the compatible equipment or test bench specified for the AP-34B system.
Set inspection covers supply, mount and connector condition, response of each channel and agreement of output with the passport characteristic. On-aircraft testing is performed with the autopilot, while bench testing follows the approved procedure. Numerical data for one DUS execution must not be transferred automatically to another angular-rate-sensor family.
Identification and ordering
Search forms include DUS-1209G, DUS-1209E, DUS-1209K, DUS1209 and the original Cyrillic ДУС-1209Г/Е/К. An inquiry should state whether a complete set or an individual channel is required. Individual cards for DUS-1209G, DUS-1209E and DUS-1209K are available in the Aviamisto Sensors category.
An inquiry should state whether the complete set or separate DUS-1209G, DUS-1209E and DUS-1209K units are required, together with helicopter type, AP-34B execution, condition and documentation needs. Links to the individual cards help identify each channel. Cross-sells provide navigation to related equipment and do not establish interchangeability.
This card identifies DUS-1209G/E/K as an individual aviation product and does not replace its passport, illustrated parts catalogue or maintenance manual. Before supply, the nameplate, condition, delivery scope, required documents and applicability to the individual aircraft or system should be agreed. When the marking, equipment record and inquiry contain different information, the approved documentation for the installed execution takes priority and any disputed parameter must be confirmed before ordering. Incoming-inspection results and traceability data should be retained with the supply documentation.
Related products are selected by common system or measured parameter. This grouping improves catalogue navigation but is not a list of approved replacements. Any substitution requires matching designation, electrical interface, mounting dimensions and range, together with explicit confirmation in the applicable maintenance documentation.
Payment & delivery
All shipments are carried out from our international warehouse in Dubai (UAE), as well as from our partners’ remote warehouses.
In Stock — items available in stock at the Dubai warehouse are dispatched within 5–10 business days after receiving 100% prepayment.
