Combustor performance characteristics can be represented in the combustor component maps. Combustor efficiency is obtained from a map if the appropriate option is selected in the combustor data entry window (per default, a constant user specified combustor efficiency is used). For primary combustors, combustor efficiency is represented in a special graph as shown below. For afterburner combustors (also an option), 3 alternate maps are used (see combustor component).

Combustor Combustor efficiency (ETA combustion) is a function of combustor temperature rise dT and Delta (Pt_in/Pstd). Only ETA combustion is scaled to a DP specified value.

In addition, pressure loss maps can be used to represent pressure loss as a function of squared corrected entry mass flow (Wcin^2).
