Main Engine Monitoring and Diagnostic Units

Generic engine monitoring unit (GEMU).

Generic unit (GEMU) has been developed and is produced jointly with Swiss company Vibro-Meter SA.

Destination:

Measuring and monitoring of the main parameters of aviation engines, including vibration parameters.

Main technical characteristics:

  • Receiving and measurement up to 30 analog inputs from sensors, which are installed in the engine
  • Receiving up to 60 discrete signals of different type
  • Receiving up to 8 ARINC-429 coded channels of low and high speed
  • Outputting up to 10 discrete signals
  • Outputting of 2 independent ARINC-429 coded channels
  • Processing of more than 20 monitoring and diagnostics algorithms
  • Processing of vibration monitoring algorithms, including tracking and broadband analysis
  • Possibility for "cold balancing" of rotors in case of 1/REV engine signal

Now units are applied in the following aircrafts:

  • Tupolev - 334 with engine D436T1(GEMU 122)
  • Tupolev - 204 with engine PS90A(GEMU 122-5)
