The engines, how can you tell?
Hello all,
I have been trying to find out how one is able to recognize the engines on the Cathay aircraft by comparing pictures with known engine types on those particular aircraft. However, I seem to be unable to get a grip on that. Generally I see two different engine pods, the ones that have parts of the core exhaust system protruding from the back end of the cowlings and the ones that don't. Initially it seemed that the latter type contained the RR engines, but looking at A340-300 photo's that does not hold up since that aircraft has CFM engines only (source Airbus website). Any pointers here? I do have a life and already have several hobbies, I am just curious...
Thanks very much!

search cathay's press releases. every order of aircraft includes an order for an engine. there are usually 3 options for every aircraft. the a340-300 only has the cfm56 because that was the only option for that aircraft. usually the engine of choice is the rr rb211-524g/h for the 747s (except for the 747-8f and the 747-400er), and the rest of the fleet is a variation of the rr trent (either the 500, 700 or the 800 series). i believe that the 777-300ers have the ge90.
you'll retain more of this information if you search the press releases yourself

to identify an aircraft engine it is best (IMHO) to look at both the aircraft type itself, and then look at the engine. it takes a bit of extra knowledge but it is a sure-fire way of identifying aircraft and their relative engine types.
for example.
the A340-300, as you mentioned, does not have a core exhaust system sticking out the back of its engines. this feature also appears on most CX 747s which use RB211-524 G/H-T engines. in this situation you should look at the aircraft type, that will give you the key to which engine it actually is. knowing the aircraft type and its associated engines will tell you that the 747 is not using the CFM56 but the RB211, and the Airbus is not using RB211 but CFM56. this is simply because the 747 does not have a CFM56 option, and neither does the A340-300 have a RB211 option.
it just takes a little research. good luck!

i guess the confusing ones would be as follows:
A340 - can be RR or CFM
B744 - can be RR or PW
for the A340 - the CFM engine does not have have an exhaust protruding from rear of nacelle - but the best clue is the size of the engine - the trent 500 is a lot bigger than the CFM
for the B744 - the RB211 has no exhaust/core protruding, the PW has a short reverser, the core of the engine is visible, and it has a large exhaust plug at the rear
hope this helps a little.

Thank you gentlemen. This is what I had so far from various internet sources (standard disclaimers):
>>This is where I tried to display a table with aircraft, orders and engines but it failed<<
I guess the shape of the pod does not always indicate the type of engine as I was determined to believe, but it is the pod shape in combination with a/c type, as hinted in previous posts. Thanks for that (and for the studying tip)!
