I’m trying to work with excel to produce a ** reasonable ** formula for thrust versus engine speed for some ** approximate ** data I have for 2 engines.

I have 2 dilemmas that I was hoping you could perhaps give me some quick guidance about:

1. Would the equation be more accurate using the form Thrust = A * Speed^exp, or perhaps Thust = A * speed^exp + B ? Or am I just complicating things with the B constant?

2. Should it matter whether speed is N1 or N2? Or is one more likely to fit a logarithmic curve than the other?

Thanks for your time, Hawk
