Abstract
The main objective of the presented bachelor thesis is the implementation of a trajectory optimizer, based on the minimization of a specific objective function, which describes the noise impact over a set of noise sensitive areas. In order to successfully achieve the desired goal, a convenient noise model is defined where the perceived noise levels are computed as a function of the aircraft trajectory (altitude, speed, thrust, etc.). In addition, the current in-house trajectory optimizer developed by UPC researchers, which before this work only allowed the optimization of the vertical profile (altitude and speed) given a fixed lateral route, has been improved to allow the optimization in the lateral domain by modifying the model describing the aircraft dynamics. Furthermore, with the purpose of obtaining feasible solutions fulfilling the requirements imposed by current air traffic management systems, a set of operational constraints are accurately imposed. Thus, the optimization problem is formulated as an optimal control problem, which is also converted into a non-linear programming problem by means of direct collocation methods. As main contribution of this work, splines interpolation functions are tested with the aim of modeling the measurement grid defining the noise sensitive areas. By doing this, a new unconventional approach is exposed with the intention of proposing an alternative methodology distinct from well-established methods based in implementing discrete points grids, offering then, a simpler way of measuring the noise impact, continuously, through the whole aircraft trajectory. Finally, with the aim of testing the performance of the optimizer, two cases are presented for which different descent trajectories are optimized from the cruise level to the interception of the instrument landing system at three different altitudes (1000, 2000 and 3000 ft). All the results are conveniently exposed with the purpose of obtaining relevant strong evidence-based conclusions. Furthermore, noise footprints are computed with the objective of providing a better visualization of the results. As the results show, the implemented methodology, where splines define the different noise sensitive areas as a continuous, differentiable function, has proven to be more than an effective method, giving very promising results on the two cases exposed.
