For most components, design point data needs to be specified to define the component operating point corresponding to the design gas turbine system operating point. Please note that "design point" as used in GSP might cause confusion, the design point of the model does not necessarily need to be an actual design point of the gas turbine in question. It is actually better to refer to the model design point as the "cycle reference point". The model reference point is usually a high power operating point where the modeler has the most avaiable data from literature, spec./fact sheets or measurement data. Usually the cruise or take off points are used for this.
Depending on the component, a number of component or design parameters must be specified in the Design tab sheet in the component data specification window. For some components also other tab sheets hold design point data such as the map design point in the Map tab sheet of the compressor and turbine components. Design point data are indicated by a navy blue color. Furthermore, since the introduction of GSP 11, design data can only be changed in configuration models or in dedicated design run case models.
