A Particle Swarm Optimization Algorithm Based Emission Optimization Method for Continuous Descent Approach

Abstract

The invention discloses a continuous descent approach emission optimization method based on particle swarm algorithm. First, the continuous approach and descent flight process of the aircraft is analyzed, and a continuous descent approach nominal track operation control model is constructed; secondly, the continuous descent approach of the aircraft is determined. Based on the constraints of the feasible trajectory and flight parameters, a continuous descent approach emission optimization transition space and an emission optimization approach space are delineated; thirdly, the Gaussian model is used as the model of the atmospheric diffusion model to establish a pollutant concentration assessment coordinate system and analyze the Decision-making variables in the model were used to find out the key factors affecting pollutant concentration; finally, with the goal of minimizing the emission concentration of the aircraft during the approach, an aircraft continuous descent approach emission optimization model was established and solved through the particle swarm algorithm. This method can delineate continuous descent approach paths for different airports that will cause minimal pollution to the airport and densely populated areas near the airport, providing corresponding reference for aircraft energy conservation and emission reduction during the descent stage in the terminal area.
