Description

KAU-115AM combined hydraulic actuator for helicopter controls

The KAU-115AM is a combined hydraulic control actuator used in helicopter flight control systems. It moves the working elements of the main rotor control system and is connected with the mechanical control linkage from the pilot. This is not a simple hydraulic cylinder. The unit works as a powered control actuator where mechanical input, hydraulic pressure, and electrical correction signals meet in one assembly. In Mi-family helicopters, this type of actuator is used where the control system requires hydraulic force and automatic correction.

Mechanical and combined control through KAU-115AM

In mechanical-hydraulic mode, the KAU-115AM transmits pilot input from the control linkage and uses hydraulic pressure to move the connected mechanism. In combined mode, the same actuator also receives correction signals from the flight-navigation complex. These signals are added to the mechanical control path and allow the system to correct the position of the controlled element. The actuator itself does not create pressure. It uses hydraulic supply from the helicopter system and converts control input into movement of the output rod.

Flight control channels with KAU-115AM installed

The KAU-115AM operates in the longitudinal, lateral, directional, and collective pitch control channels. In these channels it works with control rods, bellcranks, hydraulic supply and drain lines, feedback elements, and correction circuits. If one control channel behaves incorrectly, the cause is not always the actuator. Maintenance checks normally include supply pressure, drain pressure, output rod travel, fluid condition, linkage adjustment, electrical signal wiring, and the condition of connected mechanical parts.

Helicopter application of actuator KAU-115AM

The KAU-115AM is used on Mi-family helicopters, including Mi-8, Mi-10, Mi-6, and Mi-171 helicopters. Technical references describe it as an actuator for the main rotor control elements in longitudinal, lateral, directional, and collective pitch channels. In Mi-8AMT documentation, KAU-115AM is listed with KAU-30B and RA-60B as part of the irreversible flight control system. Exact installation and quantity should still be checked by the aircraft parts catalog and maintenance documentation.

Identification and ordering checks for KAU-115AM

Before ordering, the marking on the installed actuator should be compared with the helicopter passport, parts catalog, or official technical documentation. The product may appear in supply documents as KAU115AM, KAU 115AM, KAU-115-AM, or KAU115-AM. In Russian documentation, the same product is written as КАУ-115АМ, КАУ115АМ, or КАУ 115АМ. A clear request should include the helicopter type, channel of installation, full designation, and a photo of the data plate if available.
