RT-12-6 2ser.

RT-12-6 Series 2 System Overview

The RT-12-6 Series 2 is an aircraft temperature regulator designed for automatic limitation of gas temperature upstream of the compressor turbine. The unit operates as a critical component of the engine control system, ensuring protection against overheating.

RT-12-6 Series 2 Control Function

The regulator monitors temperature signals from thermoelectric sensors and generates control actions to limit gas temperature to a predefined threshold, preventing damage to turbine components and maintaining safe engine operation.

RT-12-6 Series 2 Aircraft Application

The unit is installed on helicopters of the Mi-8 family, including Mi-171 and Mi-172, and is used with engines of the TV3-117 series as part of the engine temperature control system.

RT-12-6 Series 2 System Integration

The regulator operates in conjunction with thermocouples and исполнительными механизмами controlling fuel supply, forming a closed-loop temperature control system. The product is also known under alternative designations RT-12-6 Series 2 and РТ-12-6 серия 2.
