Abstract
This report outlines the establishment of distributed databases for management and integration of current and future aviation fuels. Aviation fuel property and performance data has been gathered for many years in public and company specific fuel surveys. These surveys are suitable for use as overall quality control information and for monitoring changes and trends in the fuels in used for flight. In recent years, significant data has been generated for alternative fuels as part of the due diligence of their approval for use through ASTM D4054, including those outside of the specification. Recently, this data, along with fundamental chemistry data has led to the creation of the Fast Track route for fuels approval when the fuel is constrained to a necessarily narrowly defined composition. The data behind these developments are often stored in a disparate, unindexed way, resulting in their underutilisation for a range of research, engineering design, specification, and in service quality control applications. To make the best use of this data, we present a scalable, Json based format for the storing of fuels data. This concept has been proposed by the Horizon 2020 Jet Fuel SCREENing and Optimization (JETSCREEN) project in conjunction with the Center of Excellence for Alternative Jet Fuels and Environment (ASCENT) programme. We have worked collaboratively to develop a joint database which currently contains data from around 30,000 conventional and 400 alternative fuels/fuel blends from a range of European and United States of America (U.S.) lead research programmes and data sources. This database can be used for a variety of purposes, both in conjunction with, or in isolation of commercially sensitive data with a greater degree of restriction. We present a number of test cases for how we see this model for data storage could be used for the benefit of all. We invite further suggestions as to how this approach could be used and welcome opportunities to work with the wider fuels community to develop this idea further.
Highlights
The civil aviation sector has spent much of the last 60 years optimizing the design of aircraft and engines to reduce fuel consumption, lower CO2, noise and NOx emissions
In addition to the hydrocarbons, the specification places requirements on the cleanliness of the fuels and the concentrations of hetroatomic species, metal and water content. These fuel sources have not significantly changed since the beginnings of the jet age, and as such is the “Jet A-1 everybody knows,” based on accumulated experience. This means that much of the risk in the use of these fuels is mitigated through the use of this experience and trusted, standardized specification measurements used in the above standards, and the standards represent a batch certification of the fuel as safe for flight
It is clear that the overall average aromatic content is slightly less than 16%, which when blended at 50% with HEFA Sustainable Aviation Fuels (SAFs) would give a value to just satisfy the 8% minimum aromatic content requirement since aromatics content requirement since aromatic content shows linear blending properties
Summary
The civil aviation sector has spent much of the last 60 years optimizing the design of aircraft and engines to reduce fuel consumption, lower CO2, noise and NOx emissions. This has meant that the sector has been optimizing changes to the fuel systems in aircraft and ground handling hardware around a range of average, or for specific properties, the worst case fuels available In addition to the hydrocarbons, the specification places requirements on the cleanliness of the fuels and the concentrations of hetroatomic species, metal and water content These fuel sources have not significantly changed since the beginnings of the jet age, and as such is the “Jet A-1 everybody knows,” based on accumulated experience. This means that much of the risk in the use of these fuels is mitigated through the use of this experience and trusted, standardized specification measurements used in the above standards, and the standards represent a batch certification of the fuel as safe for flight
