ACARE (*) 2020 and the environmental objectives (**):

reduce fuel consumption and CO2 emissions by 50% per passenger kilometer reduce NOx emissions by 80% (associated to C02 emissions and combustion technology improvements) reduce perceived noise by 50% make substantial progress in reducing the environmental impact of the manufacture, maintenance and disposal of aircraft and related products

ACARE has identified the main contributors to achieving the above targets. The predicted contributions to the 50% CO2 emissions reduction target are:

Efficient aircraft: 20-25% Efficient engines: 15-20% (SFC improvement) Improved air traffic management: 5-10%

• Standardize repair methods.

Modeling, validation and optimization


Machining Technology

• Lower cost & higher removal rates machining

techniques (Ceramics and CBNs for Ni alloys, high

performance milling for Ti).

• Mechanized end profiling for LPT discs.

• Product surface integrity vs cutting parameters.

• Drilling monitoring systems.

• Reduced number of set ups (multitask machines).

• Optimize alumina grinding for shafts and discs.

• Optimize broaching cutting parameters.

• Vibration prediction models for machine-tool-piece to

optimize cutting conditions.

• After heat treatment residual stress modelling to

predict deformations during machining.


Measurement technologies

• Reduce the need for CMM inspection;– SPC, sampling.

– In process inspection
