While low carbon jet fuels (LCJF) offer a viable alternative to conventional in terms of reducing aviation emissions, the higher fuel costs may be passed on customers form increased ticket prices. However, there has been little research into public's willingness pay (WTP) for LCJF use. Our study addresses this gap by exploring citizen's perceptions of, attitudes toward, and premium price. We co...

Future air traffic management systems are required to balance the conflicting objectives of maximizing safety and efficiency of traffic flows while minimizing the climate impact of aviation emissions and contrails. Integrating emission and climate models together with air traffic simulations improve the understanding of the complex interaction between the physical climate system, carbon and oth...

Aircraft do not fly through a vacuum, but through an atmosphere whosemeteorological characteristics are changing because of global warming. The impacts of aviation on climate change have long been recognised, but the impacts of climate change on aviation have only recently begun to emerge. These impacts include intensified turbulence and increased take-off weight restrictions. Here we investiga...

Bio-jet fuel has attracted a lot of interest in recent years and has become a focus for aircraft and engine manufacturers, oil companies, governments and researchers. Given the global concern about environmental issues and the instability of oil market, bio-jet fuel has been identified as a promising way to reduce the greenhouse gas emissions from the aviation industry, while also promoting ene...

Abstract In order to meet the demand of high-precision flow control and modular design aviation electric fuel pump system, controller is analyzed designed from engines for pump. Tests show that steady-state deviation no more than 1% mass rate, dynamic rate 3% in range 50kg/h~2000kg/h. A with high integration degree, accuracy excellent characteristics new pump-control system was aero engine.

Over the coming years, world is projected to witness an upsurge in “drop-in” aviation biofuel production as part of renewable energy and bioeconomy developments. This paper presents a comprehensive review current status biojet fuel development uptake global commercial industry, including state-of-the-art certified technologies (i.e. Fischer-Tropsch (FT); hydroprocessed esters fatty acids (HEFA)...

The stratosphere contains haze rich in sulfuric acid, which plays a significant role stratospheric chemistry and global climate. Commercial aircraft deposit amounts of incomplete combustion products into the lower stratosphere. We have studied stability these to reaction with using predictive model based on experimental kinetics. demonstrate that acid is likely be component organics find at lea...

Previous reports indicated that inhalation of JP-8 aviation turbine fuel is immunosuppressive. However, in some of those studies, the exposure concentrations were underestimated, and percent of test article as vapor or aerosol was not determined. Furthermore, it is unknown whether the observed effects are attributable to the base hydrocarbon fuel (jet fuel kerosene) or to the various fuel addit...
