The aim of the Technology Evaluator (TE) is to measure the overall benefits of the Clean Sky project output in reducing the impact of CO2 emissions, gasses and noise levels produced by aircraft. These impacts are estimated using fuel burn, emission and noise pollution related metrics as well as on-board energy management and life cycle issues. Scenarios both with and without Clean Sky technologies are compared with respect to the 2020 and 2050 objectives. The evaluation is led by the research centres in close collaboration with the Clean Sky technology platforms. The assessment is performed at four levels:
- Aircraft level: the environmental performance of each aircraft or resulting from the Clean Sky project is assessed separately, with respect to present reference aircraft or rotorcraft for standard flights, taking into account optimised trajectories studied by the Green Systems platform .
- Airport level: the environmental performance is assessed for a number of aircraft nearby different European airports, taking into account the Air Traffic Management developments (including SESAR), and comparing the data for various fleet with a mix of standard and Clean Sky aircraft.
- Global level: the same process described above is applied at a macroscopic scale for the whole aircraft flying all around the world.
- Life Cycle level: the entire life-cycle of an aircraft/rotorcraft is assessed, from design to manufacturing, right up until the dismantling.
The leading Clean Sky Members are Thales and DLR
