Why is this A321 Engine different of others?
Hi all...until now no one could explained me why and what is the real reference of this engine, so i kindly ask your help to kill my curiosity, please:hmm:
Air Berlin has a vast & healthy fleet of 19/20 and 21, but AFAIK this specific D-ABCC is the only one in the entire fleet using this typical cone-frame »»» http://i853.photobucket.com/albums/a...luis/motor.jpg I searched in several sites, but all of them says this D-ABCC has the engines model CFMI CFM56-5B3/3, however the rest of the fleet are not similar...it has any specific name/model/serial, etc...? Many thanks for your help...JF;) |
It appears to be an option on later model A/C. Check this out:

Customer chooses what engine they want, 2 on offer for all Airbus Single Aisle Aircraft, IAE and CFM, IAE being the cheapest. Picture shows the CFM.

Also D-ABCA and D-ABCB using this type of exhaust nozzle. It's called "Chevron Nozzle". Mainly it's used for noice reduction.
It can also be ordered on other Airbus Types but the A321 ist very critical in terms of noice emission so AB decided to install it on the newest A321 only so far. I knew that Finnair use this type of exhaust nozzle on some of there A319, A320. Also Embraer has Chevron Nozzles installed on their 170, 175, 190, 195 modells. Greetings Michael |
Thanks for the pic, not seen that kind of nozzle on a CFM A321.
We don't have many CFMs (mostly IAE) so nice to see they're still improving the old smokers :ok: |
Serrated nozzles will be more and more common in years to come due to the high noise suppression requirements that jet engines must achieve prior to certification.
There are quite a few other techniques on stby at the moment, even some include a 180 degrees phase difference between sound waves, as the ones some a/c use for cabin noise suppression. Have also seen serrated CNA on the RJ 195 and 175. |
Tanx for the kind and very well explaining infos...:ok:
|
Cute
Nice livery too...kinda like an old Zeppelin in shape.:cool:
