Aircraft Fuel System Design Guidelines
|Publication Date:||1 December 2019|
This document describes the major design drivers and considerations when designing a fuel system for a large commercial aircraft. It discusses the design at a system/aircraft level, and is not intended as a design manual for individual system components, though it does refer out to other SAE specifications where more detail on specific components and sub-systems is given. It does include examples of a number of calculations associated with sizing of fuel systems, based on those given in NAV-AIR-06-5-504, as well as an appendix summarizing basic fluid mechanical equations which are key for fuel system design. It is acknowledged that most of these calculations would today be performed by modelling tools, rather than by hand, but it is considered important for the designer to understand the principles.
It is intended that later issues of this document will include appendices which give specific considerations for military aircraft, smaller commercial aircraft, and rotorcraft.
This document is intended to give fuel system designers a better understanding of the overall design process and the elements which need to be considered when designing an airframe fuel system, and an appreciation of the concepts and equations which drive the sizing of a system.
