An Efficient Application of the MOEA/D Algorithm for Designing Noise Abatement Departure Trajectories

In an effort to allow to increase the number of aircraft and airport operations while mitigating their negative impacts (e.g., noise and pollutant emission) on near-airport communities, the optimal design of new departure routes with less noise and fuel consumption becomes more important. In this paper, a multi-objective evolutionary algorithm...

Multiple-Phase Trajectory Optimization for Formation Flight in Civil Aviation

A tool is developed that is able to optimize the trajectories of multiple aircraft that fly in formation in order to obtain the minimum total fuel consumption. Several experiments are conducted to investigate the benefits of formation flight for commercial aircraft. Finally, also the influences of wind and delay on the trajectories of the...

Tailored SID & Profile Allocation for Amsterdam Airport Schiphol

Currently, only one Standard Instrument Departure (SID) track and one flight procedure is used per runway departure fix combination. In contrast to tailored arrivals, the potential benefit of tailored departures has been left relatively undiscovered. The research objective is to quantify the potential benefit of tailored SID-s and profile...

Efficient trajectory parameterization for environmental optimization of departure flight paths using a genetic algorithm

In this study, a genetic optimization algorithm is applied to the design of environmentally friendly aircraft departure trajectories. The environmental optimization has been primarily focused on noise abatement and local NOx emissions, whilst taking fuel burn into account as an economical criterion. In support of this study, a novel...

Preliminary trajectory design for a solar polar observatory using SEP and multiple gravity assists

Satellite solar observatories have always been of central importance to heliophysics; while there have been numerous such missions, the solar poles have been extremely under-observed. This paper proposes to use low-thrust as well as multiple gravity assists to reach the enormous energies required obtain high heliocentric inclinations. Two novel...

Optimal long-haul Trajectories in a Wind Field

The long-haul flights of airlines are impacted by the en-route wind fields. Flights on the same route with different directions may have significantly different flight performances. It may benefit to airlines in terms of fuel cost and on-time performance if the optimal long-haul routes are able to plan. However, the wind direction and strength...

Trajectory Optimization for a Mission to the Solar Bow Shock and Minor Planets

In November 2003 the Voyager 1 spacecraft pierced through the Solar system’s termination shock, followed by Voyager 2 in August 2007. These events marked the beginning of interstellar exploration by spacecraft, which caused a wave of renewed interest in the outer heliosphere throughout the scienti?c community. This thesis research investigated...

Terminal area energy management trajectory optimization using interval analysis

Optimization of RNAV Noise abatement arrival trajectories

Interval analysis applied to re-entry flight trajectory optimization

Trajectory optimization is an essential part of space plane mission design. One important aspect of trajectory optimization for re-entry vehicles is to minimize the total heat load at the surface when it returns and the heat flux should remain below certain limit, meanwhile, the vehicle should land at the desired point. The methods used for re...
