Military aviation fuel systems can be an ideal environment for microorganisms. Microbial growth in hydrocarbon fuel systems arises because of the impracticality of keeping fuel tanks sterile and the inevitable presence of water from condensation. Microbial contaminants in aviation fuel systems are a concern because of their potential to degrade the fuel, accelerate tank corrosion, and threaten flight safety. This research addresses the concern of using more environmentally friendly Fuel System Icing Inhibitors (FSII), which are also biocidal. Are significant levels of microorganisms growing in military aviation fuel systems, and if so, are there any common variables? Forty aviation fuel samples were collected from fuel storage tanks (including flexible expeditionary fuel bladders), refueling trucks, and aircraft from 12 U,S, military bases. Samples were analyzed using peak naming and pattern recognition algorithms of sample extracts processed on a gas chromatograph. Significant levels of microorganisms were found in military aviation fuel systems 90% (36 of 40) of fuel samples produced microbial growth. Over 40% of the serial dilutions that produced microbial growth were characterized as moderately or heavily contaminated samples. The microorganisms isolated were overwhelmingly Gram negative, anaerobic, bacilli with populations varying by orders of magnitude.

This book looks at chemmotological solutions to important questions surrounding sustainability and environmental safety of transport — both key priorities within the global strategy of sustainable development. Bringing together expanded versions of selected papers presented at the 8th International Scientific-Technical Conference: Problems of Chemmotology – Theory and Practice of Rational Use of Conventional and Alternative Fuels and Lubricants, contributors present solutions to problematic questions, including choosing feedstock and technologies of its processing for manufacturing alternative fuels, development and implementation of measures for improving environmental safety of transport, minimizing exhaust gases emission from transport, introducing new solution or improvements in systems of fuels supply and infrastructure, and changes in legislative and regulatory base for fuels and lubricants use. This collection will be an invaluable reference for researchers, professionals, and students involved in alternative aviation fuels, transport engineering, sustainable transport development, and fuels and lubricants.

Applied Microbiology and Molecular Biology in Oil Field Systems addresses the major problems microbes cause in oil fields, (e.g. biocorrosion and souring) and how beneficial microbial activities may be exploited (e.g. MEOR and biofuels). The book describes theoretical and practical approaches to specific Molecular Microbiological Methods (MMM), and is written by leading authorities in the field from both academia and industry. The book describes how MMM can be applied to faciliate better management of oil reservoirs and downstream processes. The book is innovative in that it utilises real industrial case studies which gives useful technical and scientific information to researchers, engineers and microbiologists working with oil, gas and petroleum systems.

All aspects of fuel products and systems including fuel handling, quantity gauging and management functions for both commercial (civil) and military applications. The fuel systems on board modern aircraft are multi-functional, fully integrated complex networks. They are designed to provide a proper and reliable management of fuel resources throughout all phases of operation, notwithstanding changes in altitude or speed, as well as to monitor system functionality and advise the flight crew of any operational anomalies that may develop. Collates together a wealth of information on fuel system design that is currently disseminated throughout the literature. Authored by leading industry experts from Airbus and Parker Aerospace. Includes chapters on basic system functions, features and functions unique to military aircraft, fuel handling, fuel quantity gauging and management, fuel systems safety and fuel systems design and development. Accompanied by a companion website housing a MATLAB/SIMULINK model of a modern aircraft fuel system that allows the user to set up flight conditions, investigate the effects of equipment failures and virtually fly preset missions. Aircraft Fuel Systems provides a timely and invaluable resource for engineers, project and programme managers in the equipment supply and application communities, as well as for graduate and postgraduate students of mechanical and aerospace engineering. It constitutes an invaluable addition to the established Wiley Aerospace Series.
