5349T (Right)

5349T System Overview

The 5349T is an aircraft air-oil radiator designed for cooling engine and main gearbox lubrication systems on helicopters. This version represents the right radiator, supplied as a standalone unit within the overall cooling system configuration.

5349T Cooling Function

The radiator provides heat dissipation of lubricating oil using ambient airflow, maintaining required temperature limits for engine and gearbox operation under varying flight conditions.

5349T Aircraft Application

The unit is installed on helicopters of the Mi-8 family, including Mi-17, Mi-171, and Mi-172, where it functions as part of the standard oil cooling system for engine and transmission assemblies.

5349T System Integration

The radiator is configured as a dual-section heat exchanger for independent cooling of engine and gearbox oil circuits and operates as part of a paired left-right installation. The product is also known under alternative designations 5349T and ВМР 5349Т.
