Could somebody explain me how to calculate the climb time from the maximum climb rate, because I can't correct my report.  Thank you.

RE: climb time

deltaH = ROC * t

ROC is a function of altitude.


RE: climb time

You may want to express Rate of Climb (ROC) as a function of altitude, and then integrate the expression over the altitude region which you are interested in.


RE: climb time

Thank you very much, but I found it.  The source of error may come from SFC with the thrust varying with the mach number: how do I take into account this? Thank you.

RE: climb time

Now you need engine data.  A T-v curve with lines for various altitudes is (I think) a standard format.
