I am working on a CFM56-3B2 Engine and I am having issues with Performance (Low EGT margin at T/O). I am wandiering
why CFMI does not specify the HPT Nozzle and the LPT STG 1
nozzle flow area for this Engine. There is no information
on the affects of the difference in these two flow areas
have on Engine performance.
Does anybody have any information relative to this issue?
