This paper analyzes alternative jet fuels in terms of how they could change emissions from military and civil aircraft and in terms of the challenges in meeting future energy goals. Estimations of the continental United States (CONUS) conventional jet fuel energy usage for the civil and military aviation fleets were used to inform the magnitude and logistics of where the fuels would be needed. ...
The biojet fuel production has been considered a promising strategy to partially satisfy the aviation demand. Recently, obtained from alcohol-to-jet (ATJ) process certified by American Society of Testing Materials (ASTM). In this work, modelling and simulation ATJ conventional is presented, considering as raw material bioethanol produced lignocellulosic wastes. To reduce energy requirements env...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Abstract Aviation emissions, domestic and international, account for approximately 2 % of total global CO emissions. Fuel consumption a given route, excluding other factors such as wind, depends largely on the weight aircraft. To minimise fuel consumption, it is often most economical to carry only minimum required sector. Within framework dissertation, possibilities reduce final reserve thus am...
The current push for environmentally responsible aviation requires serious efforts to mitigate the escalating effects of such technology on climate change and natural resources. A clear vision for the efficiency of future transport aircraft – with specific targets for reduced fuel burn, emissions and noise – has been published in the U.S. National Aeronautics Research and Development Plan.1 As ...
<span>Adequate fuel supply and availability are vital for economic sustainability. Aviation accounts more than 30% of an airline’s operating expenditure. Jet price is one the factors that determine airfare airlines’ profitability. Nigerian airlines run on civil grade jet A-1 fuel, almost annually, aviation sector plagued with scarcity resulting flight delays, rescheduling, cancellations. ...
The condition of the natural environment, including breathable air, indicates that actions are to be taken related reduction exhaust emissions from transport. One sectors transport is aviation. tightly types fuels in this sector In paper, authors propose application a new generation jet fuels. A full exploration physicochemical properties these requires research under actual engine operation. c...
