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.

Data showed that the same weaknesses generally prevailed in all four of the fuel systems studied. The cast aluminum components in the systems are subject to gross fuel loss and flash ignition when located outside the fuel tanks, and they present an explosive hazard from ballistic impact when located inside the tanks. Fuel transfer components are inadequately compartmentalized or shrouded, leaving the system vulnerable to vapor explosion from fuel sprayed on ignition sources. Fuel tanks mounted too low in the airframe structure are susceptible to penetration from irregular ground objects. Access ports and filler necks mounted rigidly to the aircraft structure cannot break away from the structure; in a crash environment the tanks tear away from these highly stressed fitting areas and severe fuel loss ensues. The fuel transfer outlets are mounted rigidly to the structure with no provisions for separation during a crash. Fuel-level indicator probes present a puncture hazard to fuel tanks. Fuel transfer lines generally consist of tubing that cannot withstand excessive deformations. Even flexible hose lacks the extensibility to withstand gross structural deformation. Since no self-sealing breakaway fittings are provided, either fittings or lines will fail. Rigid fuel line connections to bulkheads prevent line displacement and are another cause of fitting and line failures. Highly extensible fuel transfer lines, typified by the self-closing line, and properly located self-sealing breakaway fittings will reduce the problem of fitting failure by preventing load transfer to the fittings.
