8AT-2710-000

Lift generation through the 8AT-2710-000 blade

The 8AT-2710-000 blade generates lift as it rotates with the main rotor hub. Changes in collective and cyclic pitch alter blade angle and allow the helicopter to climb, descend, hover and maneuver. The blade must maintain stable aerodynamic characteristics across the full operating envelope, including changing airflow, vibration and load distribution along its span. Its rectangular planform, modified NACA-230 profile and geometric twist support the required lift distribution along the rotor radius. The twist helps balance induced velocities and lift between the root and tip areas of the blade.

All-metal construction of 8AT-2710-000

The 8AT-2710-000 blade has an all-metal construction based on a pressed aluminum alloy spar. Trailing edge sections are bonded to the spar to form the rear part of the aerodynamic profile. This structure provides stiffness and strength while keeping the blade within the required mass range for the Mi-8 rotor system. The blade has a rectangular planform and constant chord on the regular working section. Its structure includes multiple bonded tail sections, which form the aft part of the airfoil and must remain in correct condition for aerodynamic performance and structural integrity.

Protection and monitoring systems in 8AT-2710-000

The 8AT-2710-000 blade is equipped with an integrated spar damage monitoring device and an electro-thermal anti-icing system. The spar monitoring system is intended to support control of structural condition during operation. The anti-icing system heats the blade and allows operation in icing conditions according to the aircraft documentation. These systems are part of the blade’s operational suitability and should be checked together with the blade passport, aircraft maintenance records and service bulletin status. Electrical continuity, heating system condition and spar monitoring data are important during inspection and acceptance.

Application of 8AT-2710-000 on Mi-8 / Mi-17 helicopters

The 8AT-2710-000 main rotor blade is used on Mi-8T, Mi-8MT, Mi-8MTV, Mi-17, Mi-171 and related helicopter variants. It is installed as part of a five-blade main rotor set on compatible main rotor hubs. The blade may be supplied individually or as a complete set of five for one rotor system, depending on maintenance requirement and availability. Since Mi-8 family helicopters may differ by modification, manufacturer, overhaul history and service bulletin status, applicability must be confirmed through the aircraft parts catalog, blade passport and approved operational documentation.

Identification and service control of 8AT-2710-000

The blade may be referenced as 8AT-2710-000, 8AT-2710-000, 8AT.2710.000 or 8AT2710000. These designations refer to the same main rotor blade type, but exact applicability and remaining life are controlled through documentation. Assigned resource, calendar life and possible life extension are defined by manufacturer bulletins and inspection results. For supply, the buyer should confirm whether the requirement is for one blade or a full set, the required condition, remaining resource, passport availability, anti-icing system status, spar monitoring status and compliance with applicable service bulletins.
