Here's some photos of one method. If I remember correctly from previous posts on this topic, certain airliner types are fitted with a fifth engine mount for the purpose of transporting engines that are new or need repairs, etc.
By hanging the 5th engine from a wing for transportation (sometimes with an intake cover fairing to reduce parasite drag and ware on unlubricated engine bearings) the engine dosen't need to be dissasembled as much in order to get it to fit into the cargo hold. I believe this is what I learned.

I'm not too sure here but I think engines are not assembled in the UK, it is ferried in parts in a cargo plane to Boeing for example, where RR engineers will assemble them to a piece.
I don't think engines are ferried as a fifth pod, they are only used by some airlines to fly an engine to somewhere for a plane that needs an engine replacement. Anyway, I don't think you can fit a RR trent under the wings of a B747

Engines are carried to aircraft manufacturers on cargo planes or other means, the "5th pod" on a 747 is strictly for transport of spare engines in case an airplane has an engine failure in a location away from the base...

We overhaul engines and have shipped and moved up to JT3Ds.
We use the back of a truck for local movements (air suspension flat bed required for turbofan engines, otherwise damage occurs to blades, bearings etc due to road roughness)
JT3D fits in nicely in a DC8 or B707 freighter.
For a cheaper option we have also sent by sea in standard 40 foot containers but that is mainly engines that need overhaul....so any damaged received is not urgent, as engine not immediately going on wing and engine is being stripped.
Engines are often airfreighted....we just received an air freighted engine from Asia. The freight company askes the size and weight and looks around for space on existing scheduled carriers flying the routes
Never shipped a really big turbofan though.

I would doubt that the story re the L100-30 is true ... imagine the number of stops it would have to make between Derby and Palmdale!
On the other hand, the Conroy CL44 Guppy was built specifically to move RB211s for Lockheed. Now, the L1011 freighter can carry three complete engines (the smaller door on the DC10 means that the fans have to be removed).

A 747F can take several engines at any one time. We've done several different types up to 747 size locally. It's really no big deal. You can do 777 engines, but it's real tight. Usually it is overhaul stuff going back out, not newly manufactured.
is that a light at the end of the tunnel or just a train?

>>A 747F can take several engines at any one time.
I was under the impression that Boeing only allowed for one additional engine to be carried under the wing (the so called "5th engine"). Am I wrong here? I'm not questioning your credentials, I'm just curious. I'm also having a brain fart about now.

When I see a photo of a jet engine like the one on the DC-10-30 below, I can't help but wonder what all the different components are which are located around the outside of the engine's casing.
Thanks to you guys, I've learned a lot about what certain pieces of equipment found attached to the side of a jet engine are used for, however, I would really like to learn much more. It's a new found interest for me.
So....Does anyone know the name of some good technical books on jet engines that I could find that would teach me in detail how they work and where certain components are located?
I'm specifically interested in airliner engines, also, I'll be 36 in November so I should be able to handle many skill levels of text explanation.
Here's a few questions of curiosity you might be able to help me with in the meantime.
What type of DC-10 engine is in the photo above? (I know it's likely a Hi-Bypass Ratio Turbofan, but what is it's rated thrust and who makes it...GE or RR for example).
Also, in the photo above you can see a grey coloured football shaped container on the bottom right side of the Fan/Compressor casing, a gold coloured tube attached to the middle, and multiple red hoses, etc. Can someone explain what these components are, or are they hard to pin-point? To me the bottom-front of this DC-10's engine looks like a giant circuit board! I love it.

Rolls Royce created a book many years ago called "The Jet Engine" It is old, but many of the principles of jet propulsion have not changed much. Many engineering schools still use it for training. I will see if I can find my copy and get an ISBN for you. I am sure it is still available.

I had to get my copy the "The Jet Engine" from Rolls-Royce directly, it is a very good book, updated in 1995 (I think) and costs around 20 pounds (again from the top of my head). You can find it on their webpage
