IR-117M

IR-117M System Overview

The IR-117M is an aircraft engine operating mode meter designed to monitor engine operating modes based on air pressure downstream of the engine compressor within the engine control and indication system.

IR-117M Measurement Function

The instrument measures compressor outlet air pressure through dedicated pressure receivers and applies corrections for altitude and temperature to ensure accurate assessment of engine operating conditions under varying flight environments.

IR-117M Aircraft Application

The unit is used on helicopters equipped with compatible engine systems, including platforms of the Mi-8 family, and provides flight crew with data required for selection and maintenance of takeoff, nominal, and cruise engine operating modes.

IR-117M System Integration

The instrument operates as part of the engine control and indication system, interacting with pressure, temperature, and correction sensors to deliver reliable operating mode indication. The product is also known under alternative designations IR-117M and ИР-117М.
