Quick start basics - Building a GSP model .

1.	Open the afterburner combustor data form.

2.	Select the General tab sheet.

Here it is selected whether the combustor is a normal combustor or an afterburner.

3.	Select the Use afterburner combustion efficiency maps radiobutton.

The Burner duct cross area variable appears.

4.	Select the Design tab sheet.

5.	Set the design fuel flow to 2.5 kg/s.

The afterburner incorporates a significant higher fuel massflow than the normal combustor.

6.	Set the rel. tot. pressure loss at design point to 0.12.

7.	Check the Zero Wf in design Calc. (afterburner) checkbox.

When enabled, the engine is designed without afterburner, and the afterburner is only used during off-design simulation.

8.	Select the Map tab sheet and browse for the following maps (from top to bottom): ETAABfarrel.map, ETAABmrel.map, and ETAABprel.map and set the storage option to Local.

9.	Select the Output tab sheet and check the output variables desired.

10.	Click OK to close the afterburner combustor component data form.

Now that the model has been completed, it is time to run simulations to test the validity of the model and analyze performance.
