EMU
Chassis Wired AV160, Pt No. C142270-1, #105, Microtecnica
EJ2000 Engine
The Engine Monitoring Unit (EMU) was suppled to Eurojet as an accessory to the EJ200 Engine. Using data derived from links with the digital engine control units and engine mounted sensors the EMU provides Monitoring & Data Recording Analysis functions for both engines, such as monitoring life usage and engine vibration, Compressor Turbine Rotation and Oil Debris Monitoring. The EMU records engine incidents and performance and provides engine failure detection and location. Overall the system gives reduced scheduled engine maintenance.
The EMU consists of four computer modules, power supply and chassis wired and was fitted to DA3 onwards. The EMU is fitted under the forward end of the EJ200 Engine.
An international consor¬tium led by Monitoring and Control Division, with Litef of Germany. Microtecnica of Italy, and Inisel of Spain supplied the Engine Monitor¬ing Units (EMU). The contracts cover the design and development of the equipment, the supply of prototype hardware and full product support to Eurojet, the Munich-based group undertaking development of the EJ200 engine.
GMAv was the prime contractor for the unit development, which included tests on a number of engine test bed facilities and completion of qualification testing for flight rating of 6.000 hours. A Production contract was awarded in 1991.
The EJ200 has been upgraded and a new Digital Engine Monitoring Unit has been fitted.
