Efeitos no consumo de combustível e emissão de poluentes pelo uso de altitude variável durante o voo de cruzeiro

Abstract

The growth in air traffic, especially on low-cost flight, combined with the increase in oil prices and the growing concern with environmental impacts, increase the aeronautical sector research for ways to reduce fuel consumption and, consequently, the emission of air pollutants. In this dissertation the theoretical basis necessary to the modelling of the cruise flight is established, making it possible to implement a step-climb and a cruise-climb simulation routine. The aerodynamic and propulsive models are determined and validated. After the simulation is concluded, the results are presented and discussed, evaluating the cruiseclimb method efficiency on consumption and pollution reduction. The obtained results are inconclusive, with small differences in consumption between Step-Climb and Cruise-Climb simulations. Finally, suggestions to achieve the desired results and for future studies are presented.
