Generic Engine Monitoring System

Generic Engine Monitoring System for gas turbine powered aircraft developed and production by  Vibro-Meter SA. Abris JSC is subcontractor for Software of Engine Monitoring part and for support of GEMS evaluation on the engine test bench and on the aircraft.

PURPOSE:

Generic Engine Monitoring System (GEMS) is a single channel, digital, generic system that integrates in one system functions of the Engine Interface and Monitoring and Engine Vibration Monitoring.

Main technical characteristics:

  • comprises a Generic Engine Monitoring Unit (GEMU), two engine vibration transducers and engine and aircraft vibration cable assemblies
  • GEMU provides for an on-board measurement and processing systems that monitors and provides diagnostics of engine and its components. GEMU is designed in standard ARINC-600 case (4 MCU)
  • GEMU is designed to be installed in an electronic bay of the aircraft
  • GEMU was designed in the "generic" way to provide monitoring of four different combinations of aircraft/engine (Tu-324 and Tu-334 with D-436T1, AI-22, BR710 and CF-34)
  • For Tu324/334 the GEMU provides interfaces with 19 analog inputs, 63 discrete inputs, 7 ARINC-429 inputs buses and with 8 discrete outputs, 2 ARINC-429 outputs buses

Software function:

  • Monitoring of oil and air-oil systems
  • Monitoring of the Fuel System
  • Definition of the engine operation mode
  • Monitoring of the Surge System
  • Monitoring of the engine rotors run-down time
  • Monitoirng of the compressor mechanization
  • Calculation of the engine usage time
  • Monitoirng of the engine starting system
  • Monitoring of engine basic parameters
  • Monitoring of engine vibration
  • Monitoring of engine intake de-icing system
  • Monitoring of thrust reversor
  • Maintenance function including recording of events and fault history

First application:

Tupolev-334 with D-436T1 engine
