This innovative, new software system provides aerospace design engineers with a Windows-based, graphical user interface for design, analysis, development and simulation of aero-thermodynamic systems. This software has the benefits and advantages over existing simulation and performance design software tools by enabling the design engineers to rapidly synthesize, architect, re-parameterize, simulate and analyze new aero-thermodynamic systems with visual components.

The software allows simple and rapid assembly of design with built-in detailed physics and aero-thermodynamic properties of the gas turbine components. This software significantly increases the ability of the designer / simulation engineer to utilize his/her creativity and innovative skills to architect and configure gas turbine engine systems from an almost infinite possibility of interconnected, move-able and easily re-parameterized components on a design pallette.

The complex gas turbine engine component equations are already developed, implemented, and ready for system design. The user simply uses his computer mouse to click to:
1) Select the components,
2) Drag and drop them into place on the design pallette,
3) Connects the appropriate inputs/outputs,
4) Utilizes the user-friendly window tabs to custom parameterize the components,
5) Clicks the Simulate Button.
The System results can then be viewed interactively during the simulation and after the simulation using Excel ® or other plotting tools of the user’s choice.

The three visual illustrations included with this entry show:
1) The software screen with the design and simulation of a Single Spool Gas Turbine Engine controlled by a Dual Loop (Turbine Speed and Turbine Exit Temperature) PID Controller.
