Thrust power

[disidd]

Hello.  I found out in the planemaker that the thrust power is 27K, and the plane is designed for a thrust power of 20K.  This is mistake?

I understand that CFM56-3-B1 engines with a thrust power of 20K were installed on the 737-300, and 27K rather corresponds to the 737-800 model with CFM56-7B27 engines

The CFM56 engine we modeled is RATED to 20K thrust. It can put out much more, but that would mean going beyond it´s rated limit (and possibly damaging the engine).

The pilot is responsible to not strain the engine too much (with the help of the PMC and FMC).

This means that at sea level ISA conditions, you should not run the N1 higher than 90.5% to gain 20K thrust.

Cheers, Jan
