737 Static Thrust

[philsymonds]

I seem to have aquired a shed load of 737's, ranging from the 200 series up to the 800.  There's a massive variance of static thrust figures in different flight models.  Even those of the same type!  I have one 737-400 with 23,500 and a 737-500 with 29,950.  That seems way too high.  Anyone know the correct numbers?

The 737-500 has a engine rating of 18.500 or 82.3 kN
The 737-400 is rated somewhere around 22.000 (97.9kN)
I'm at work now so I don't have the exact figures, I might be wrong. Will double check later.

Hello Phil,
what engines do you think they use as different airlines use different  on the same series?

Oh Ian, we don't wanna go there
I believe the 737-500 can be fitted with 2 different types of the CFM56-3, both with different thrust settings.
I think the 18.500 corresponds to the CFM56-3-B1R

According to CFM, their CFM56-3 series has a rating ranging from 18,500

Hello Nexus, so lets go here:
CFM56-
3B1 20000 lbst 737-300/500
3B2 22000 -300/400
3C1 23500 -400
7B18 19500 -600
7B20 20600 -600/700
7B22 22700 -600/700
7B24 24200 -700/800
7B26 26300 -800

Did I miss anything? I also have SFC & eng weights.

Well, the CFM56-7b series is only fitted on the Next Generation 737's.
The 7b-series has a better climb and cruise thrust performance than it's predecessors, which is needed since the NG's are heavier than earlier versions.

The 737-600 has to be the most overpowered Boeing aircraft ever.  :)

Thanks, more than enough info there
