|Quoting skopsko (Thread starter):|
1. The different colored metal panels (white, gray, etc.) on the forks that holds the engines. It looks unfinished. This is not the case with Boeing planes whose forks are covered with one, congruent metal sheeting.
The objects which hold engines to wings are called "pylons," most of the time.
They are not all metal on the Airbus; the metal portions are unpainted, yes, but the composite portions are painted. Much as AA
treats its planes- 737 fuselages are (until last week, anyway) unpainted, while the wing-body fairing and vertical stab (and lots of other bits and pieces) are painted.
Also, I think Airbus uses a hot pylon concept, while Boeing's is cool. Don't remember the details there, but I think I read something about it a while back.
Basically, Boeing puts the bleed air precooler in the engine case, so only "cool" air ducting is in the pylon, whereas Airbus supposedly puts the precooler in the pylon, creating a so-called "hot" pylon.
I don't know- I've never touched an A320/330/340 engine or pylon, I only work on Boeings.
