Fuel system Flashcards
System design influences
engine specific, fuel consumption operational range storage space structural loading safety servicing and maintenance
Storage
means of storing fuel in tanks on the aircraft, including fuel quantity measurement, pressurisation and venting
Integral tanks
fuel stored in a sealed mainplane or stabiliser torsion box
External tanks
fixed tanks to provide additional fuel capacity
Tail tanks
used to trim the aircraft
Vent surge tank
used for venting positive air pressure
Fuel quantity measurement methods
capacitance method ultrasonic method

Cavitation
It is defined as the process of formation of the vapour of a liquid when under reduced pressure at a constant temperature
Fuel feed
provides a supply of fuel to the engines
Fuel transfer
