Hi all!
Can anyone pls help?
I know the definitions of EPR and N1 and how they work etc..
But why does the 747 RB211 use EPR vs the Cfm which uses N1...
It seems like the newer generation engines are using N1. Is this due to the increasing by pass ratios and if so why?
Have checked previous 100 days threads and apologise if i've missed the simple obvious answer...
Thanks in advance!
