What is GSP ?
|
|
The Gas turbine Simulation Program GSP, a component based modelling environment, is
NLR’s primary tool for gas turbine engine performance analysis. GSP's flexible
object-oriented architecture allows steady-state and transient simulation of any
gas turbine configuration using a user-friendly drag & drop interface with on-line
help running under MS-Windows. Gas turbine configurations are simulated
by establishing a specific arrangement of engine component models in a model window
(view an example model window).

Implementation
|
|
For several decades, NLR has been presented with a wide variety of gas
turbine engine performance problems. Both military and civil engine operators
and manufacturers have been internationally supported with projects
related to engine performance and handling, diagnostics, fuel consumption,
health monitoring, etc. Therefore, simulation tools with a high degree of
flexibility are required. GSP was developed to allow rapid adaptation to various
problems rather than being dedicated to a specific task. The Windows platform
was selected in view of the rapid increase in available low-cost computer power,
combined with the wide scale use of this operating system. GSP is implemented
in the Borland® Delphi (TM) object-oriented environment, offering excellent
means to maintain and extend the program. With the Windows platform, GSP
has a user-friendly graphical drag & drop interface with on-line help
allowing quick implementation of new engine models and rapid analysis of
a wide variety of problems.

Development
|
|
During continuous development, GSP has been extended and improved with
new features for specific applications. GSP version 8 includes a chemical
gas model and a generic multi-reactor 1-D combustor model based on the NASA
CEA model. Combined with a detailed specification of fuel composition,
it provides a means to calculate effects of fuel and gas composition and
water or steam injection on gas turbine performance and emissions, including
dissociation effects. The gas model is used throughout the entire engine
cycle calculation. A new biomass gasifier component has been developed
for performance analysis of integrated gas turbine-biomass gasifier systems.
