Abstract
In this paper are reported Selex results of the tests, performed in a simulation environment, of multi-object trajectory optimization algorithms, for weather avoidance and emissions reduction. These optimization algorithms, developed under European Clean Sky project, are based on operational research concepts, and they are aimed to calculate optimized trajectory in terms of several emission reduction. The emissions to be simultaneously reduced are CO2, proportional to fuel consumption, NOx and noise. The simultaneous reduction of all these three pollutants is nontrivial as reducing one pollutant can lead to an increase in the others. The chosen approach, to reduce simultaneously the different emissions, is to combine the different pollutant using a linear combination of the weighted emissions. The automatic generation of the optimized trajectories is later validated in realistic flight simulator to verify the results with an easy, safe and economic way.
