Clean Demonstrator
Clean (component validator for environmentally friendly aero engine) is a European technology demonstrator program under the direction of MTU Aero Engines. Its special feature: The concept is based on geared fan technology and includes a heat exchanger. It affords substantial fuel savings as well as significant noise reductions.
Combustor
In the combustor, the air coming from the compressor is mixed with fuel and burned. This creates extremely high pressures and very high temperatures of well over 2,000° C. All the hazardous substances which the engine emits are produced in the combustor. Therefore, an attempt is made today to lower the level of these hazardous substances – especially of nitrogen oxides – by changing the injection and mixing concepts in the combustor. Because of the high temperatures, the combustors are provided with special thermal protection.
Compressor
The compressor consists of several stages of bladed compressor disks that rotate at very high speeds between stationary guide vanes. Large volumes of air are ingested and compressed greatly before being passed into the combustor. To achieve the compression ratio of over 30:1 of current engines, two different types of compressors are used: the lowpressure and the high-pressure compressor. These compressors are driven at different speeds by the associated turbines via concentric shafts.
Control and Monitoring Systems
The control system comprises the individual devices used to monitor the engine and to control the fuel supply system, actuation of guide vanes and nozzles, bleed-air system and lubrication system, as well as the necessary sensors for engine speed, pressure, and temperature.
Cooperative Model
Under the Cooperative Model, the maintenance activities for aircraft engines operated by the German Armed Forces (Bundeswehr) are pooled under the umbrella of industry. The Bundeswehr is closely involved in all procedures, with airmen and MTU personnel working shoulder-to-shoulder.
Corporate Governance
Corporate governance refers to the rules of good, value-oriented corporate management. The principles of corporate governance are aimed at promoting trust in the company among investors, customers, employees, and the general public.
D&O Insurance
D&O insurance covers liability risks resulting from the execution of professional or official responsibilities in a company (= director and officer liability insurance).
DECMU
The DECMU (digital engine control and monitoring unit) is an engine subsystem for the complete digital control and monitoring of the engine. Normally, there are two separate units for these two functions. In the DECMU, they are integrated into one single unit.
