UR-117M System Overview

The UR-117M is an aircraft engine mode indicator designed to display parameters used for monitoring engine operating modes as part of onboard indication systems.

UR-117M Indication Function

The instrument provides visual indication of compressor outlet air pressure, atmospheric air pressure, and outside air temperature, enabling assessment of engine operating conditions during flight.

UR-117M Aircraft Application

The unit is installed in the cockpit on aircraft equipped with IR-117 / IR-117M systems, including helicopters of the Mi-8 / Mi-17 family, depending on configuration.

UR-117M System Integration

The indicator receives signals from pressure and temperature sensors and displays processed data for flight crew use, operating as part of the engine control and indication system. The product is also known under alternative designation UR-117M.
