5349T (Left + Right Set)

5349T System Overview

The 5349T is an aircraft air-oil radiator unit supplied as a комплект of left and right radiators, designed for cooling engine and main gearbox lubrication systems on helicopters. The unit operates as part of the onboard thermal management system, ensuring stable temperature conditions of critical assemblies during flight.

5349T Cooling Function

The radiator unit provides heat dissipation of lubricating oil using ambient airflow, maintaining required temperature limits for engine and gearbox operation. The combined left and right configuration ensures balanced cooling performance across the system under varying operational 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 serves as a standard component of oil cooling systems for both engine and transmission assemblies.

5349T System Integration

The комплект consists of two radiators (left and right), each configured as a dual-section heat exchanger for independent cooling of engine and gearbox oil circuits. The unit is integrated into the aircraft lubrication system and is interchangeable with аналогичные radiator assemblies used in helicopter oil cooling systems. The product is also known under alternative designations 5349T and ВМР 5349Т.
