How Do Engines Get To The Assembly Line?

Tue Apr 25, 2006 1:07 am

I know its a stupid question but
How do the Giant RR, GE or Pratt & Witts get to the airframes ?
Do they get flown in ? and if so on what ?or are they driven in on trucks ?
or are they assembled on the grounds of the assembly line ?
I.e The RR Trents... Big Mama engines.. how do they get to the Boeing 777 airframes ?
Thanks guys....

Years ago when I worked in the Cincinnati & Indianapolis areas I would see crated CF6 (GE) engines on trucks west bound on either I-70- or I-74, thus presumably to Long Beach and Seattle for installation on aircraft. The crates were pretty large and I believe there were 2 per truck.

Hope this helps

Not stupid at all....I've also wondered about this... smile 

Further, at what stage do the engines get attached to the aircraft.....say, if a 777 takes 'x' number of weeks to assemble and finish (someone kindly provide the value of 'x'), at what point are the engines attached??

US I-40 and 18 wheels a rolling...!

I've seen it dozens of times. In most cases the fan section is removed due to size and later added at the point of assembly.

Assembled at a plant near Boeing Field in Seattle, trucked to which ever factory they're going to (Renton or Everett) and hung in the factory during final assembly. Don't know how they do it on the other side of the pond.

Go to the GEAE web site and it will answer your questions. They even have 2 great little videos that show how the GE90 works, and even how it gets shipped.

Thanks! Neat to know that the GE90 is produced in my backyard  Smile

Thanks for the info guys...
But If some engines are produced in NC and Boeing for instance is in Seattle.. thats a lonnnng drive...
Do engines ever get flown in ?
I mean the Huge RR Trents are massive !! ...also do RR produce the Trents in both the USA and Europe ?? and if so where ??
Im really curious about large part assemble and transportation ! haha
as you see !!  Wink

I had seen a picture of a spare jet engine hung on the wing alongside the regular engines. Although that must have been from a central maintenance base to a remote airport where another company bird needed an engine change. This was about 10 years ago, and the engine was not as big as the current generation of powerplants.

With the weight of the engines and the cost of air freight, I'm sure a very thorough cost comparison is made before engines are flown rather than trucked, rolled in rails, or shipped. Leadtimes are planned so assembly is not disrupted.

Here I know that Perm engines (PS-90's) are delivered by train to Voronezh, Ulyanovsk or Kazan from Perm and then taken by truck to the assembly plant. Rolls Royces are flown in to Ulyanovsk.

we have carried umpteen aircraft engines on the AN124
for a few months we carried the GE engines to boeing field for the B777 and the AN124 ws the only aircraft where they fitted on as they are so big

Just to be a bit more specific, engines are almost always shipped to Boeing from Pratt and GE via air ride trucks with either two engines per truck or often one engine per truck and about 6,000lbm ballast (to ensure the smoothest possible ride).

That said, I have seen quite a few go out from Hartford via Polar air Cargo to both Seattle and Airbus.

Rail is never used as the delivery times do not work well with "just in time" delivery. (Rail companies still can have delays measured in days.)

Often Air is utilized when a mistake is made assembling the engines and time must be made up. Its cheaper to air freight a small number of engines a year than to budget 3 more days in the assembly process for all of the engines.

This doesn't suprise me. Boeing charges pretty hefty penalties for late engines and for a while GE was behind in building GE-90 fans... so I do not doubt quite a few were in your Antinovs.
