Low Emissions Core-Engine Technologies (LEMCOTEC)
Date du début: 1 oct. 2011, Date de fin: 30 juin 2017,
The main objective of the LEMCOTEC project will be the improvement of core-engine thermal efficiency by increasing the overall pressure ratio (OPR) to up to 70 leading to a further reduction of CO2. Since NOx increases with OPR, combustion technologies have to be further developed, at the same time, to at least compensate for this effect. The project will attain and exceed the ACARE targets for 20 ...

Innovative counter rotating fan system for high bypass ratio aircraft engine (COBRA)
Date du début: 1 oct. 2013, Date de fin: 31 mars 2017,
The purpose of COBRA is to use technology breakthroughs to overcome the insufficient noise performance of the counter-rotating fan tested in VITAL FP6 Program. This will be achieved through exploring higher by-pass ratio (15-25) resulting in much lower blade tip speed and blades count. The designs shall comply also with higher or equal aerodynamic efficiency compare to the VITAL ouputs.COBRA is s ...
