Vic,
As you might have guessed from all these answers mate, it is pretty automatic.
Not in the same way as you describe though. The fuel systems as a whole will operate the same way if we were cruising at 1g for the whole trip, or if we were busy throwing ourselves aound the North Sea at 7g (
)
The systems are designed as such, that under all situations and operating conditions, they operate in the same way.
In Tornado for example
Tanks feed from Fin, FR groups, O, UWings, Wings (Not before 3250kg L Peacock before you start
) Wings, Main Group.
This in it's self ensures that all C of G limits are contained.
Sorry to bore you all again
Speke,
Imagine how large and solid those fuel pumps would have had to have been to consistantly produce 1400 psi (95.2 bar)
And we\'re talking over 40 years now!
Even in the combustion chamber, we\'re talking about pressures that are at their maximum 160psi, So why on earth would you need a 3340 psi differential at the injectors?
You wouldn\'t would you?
Sorry to be pedantic
3 Years as a JT apprentice A/P made me this argumentative
