The steady state series calculation mode enables the calculation of a series of steady state operating points with varying off-design operating conditions. These "parameter sweeps" are applied to determine the relation between engine performance and a specific parameter, for example fuel flow from idle to max power. Therefore, steady state operating point calculations are required over a wide operating range. Usually only a single input parameter is varied for a parameter sweep to obtain a clear indication of the effect of the parameter, but multiple parameters may be varied simultaneously if desired. GSP steady state series calculations offer a flexible way to apply input parameter sweeps using the time-function tables also used for transient simulation input. The tabular time input function is used to specify the input parameter values at which a steady state calculation is required. Although the time parameter has no physical meaning for a steady state series, it is used as a scale to define a series of input parameter values. The transient output time step setting determines the intermediate input values for steady state calculations between the specified input values in the transient input table.
