High Bypass Jet Engine

[RowlSidd]

I am currently analysing the high pressure turbine disc in a jet engine. Is it possible to derive a relationship between the rotational speed of the spool to the inlet mass flow rate? I have the RPM of the spool at varying stages of a flight profile, I need to determine the mass flow entering the engine.

Mass flow related to thrust and thrust is usually specified for each mission (U name it stage of flight), together with altitude and aircraft speed. You can find MFR by simulation of engine cycle. Recently I saw one online tool and there were jet engines in samples. Search for "software for heat balance calculation of gas turbine cycles"
