Can anyone tell me where I could find detailed information for fuel burn data on this engine? I've looked at CFM's site and also the technical specs at Boeing's and I can't find what I am looking for.

sorry can't help you

I heard Southwest is starting a drastic GE kit cfm56 upgrade.

Is this a good idea, are more airlines considering this mod ?

I was looking for some detailed information about fuel data like: fuel flows, fuel burn in time, etc
I was looking at the site of cfm and boeing aswell, but then I searched here and found this topic.

Can anyone please help me to get some detailed information for the cfm56-7b22K/24K/26K/27K?

Quoting tiago1991 (Reply 3):

A good start maybe to look up the FAA and EASA type certificate data sheets for the engines of interest;

http://rgl.faa.gov/Regulatory_and_Gu..._Library/rgMakeModel.nsf/MainFrame

http://www.easa.europa.eu/certification/type-certificates/engines.php

A few examples to get you started may include;

http://rgl.faa.gov/Regulatory_and_Gu...74246/$FILE/E00056EN%20Rev%209.pdf

http://rgl.faa.gov/Regulatory_and_Gu...32041/$FILE/E00055EN%20Rev%209.pdf

http://www.easa.europa.eu/certificat...-7B_series_engines-04-17122012.pdf

These documents tend to give a variety of detailed information that is not found elsewhere. The following should help with fuel flow data;

http://books.google.com.au/books?id=...&q=GE%2090%20Elodie%20roux&f=false

http://www.stanford.edu/~cantwell/AA...urse_Material/GE90_Engine_Data.pdf

IIRC, there may also be more detailed data on fuel flows if you look on the EPA website or search for studies and documents to do with emissions testing.

Thank you very much for your quick answer!

I've another question.
Is there detailed info about the fuel flow, per weights, miles nm, minutes etc like performance data
For example:

For a Boeing 737-700 from DAL - cfm56-7b26
Klm B738 - KLM -cfm56-7b24, etc

The only thing close to that which I can think of are the specific payload-range charts from Boeing;

http://www.boeing.com/assets/pdf/commercial/airports/acaps/737sec3.pdf

Actual hard numbers such as specific fuel flows, distances and sector times for the various CFM56-7B subtypes would most probably be proprietry data held by airlines.

Search through the Civil Aviation forum, as there have been many threads revolving around the in-depth analysis of various aircraft / engine / route combinations. Your best bet for the 737 would be to search specifically for 737MAX or A320NEO threads. If you find a 737NG thread, I'm sure you could reverse calculate a set of numbers that are reasonably close to the actual quantities you want.

I heard this about 10 years ago for the -300/500 series to bring them up to -7B22 standards. I assume this never occurred.

The most reliable public fuel burn data is the ICAO emmision databank:

http://easa.europa.eu/environment/edb/aircraft-engine-emissions.php

This gives the fuel burn figures for uninstalled engines (ie test stand config, you should add about 3% for installation losses) for flying around an airport, thus not cruise data unfourtunately. For cruise TSFC and thrust this web site is the best I have found, most of the data is reliable:

http://www.jet-engine.net/

The one for the CFM 56-5C is bogus, should be about 0.58-0.59

A ten-years-old thread still active?

I thought Keesje was back…
