Aircraft-produced contrail cirrus clouds contribute to anthropogenic climate change.
Observational data sets and modelling approaches have become available that clarify …

The sustainability of air transport is increasingly studied in relation to climate issues. The
objective of this paper is to provide the key elements for assessing whether a given …

In recent years, renewable energy resources have become more important due to the limited
number of regions for production of petroleum-based fuels, which are continuously …

Crude oil price volatility directly affects the worldwide fuels and chemicals markets, impacts
food production costs, as well as it influences investments in alternative energy sources …

This study assesses an integrated biorefinery model's efficiency for biojet fuel production as
Jet A1 blending component through the Alcohol-to-Jet (ATJ) and Hydroprocessed Esters …

Exergetic performance and exergoeconomic analyses of a small-scale turbojet engine
fuelled with either conventional aviation fuel or biofuel are conducted; and the performance …

A conceptual framework to predict microphysical and optical properties of contrail particles
within a wingspan behind the source aircraft is developed. Results from two decades of …

The life cycle of individual (initially line shaped) contrails behind aircraft and of contrail cirrus
(aged contrails mixed with other ice clouds) is described. The full contrail life cycle is …

Aircraft soot has a significant impact on global and local air pollution and is of particular
concern for the population working at airports and living nearby. The morphology and …

The main objective of this study is to investigate the thermodynamic, environmental and
sustainability performances of turboprop engines used on unmanned aerial vehicles (UAV) …
