INTRODUCTION (1)INTRODUCTION (1)

EcosimPro is the ESA software tool for the simulation of ECLS systems.

EcosimPro was designed as two parts:

> A Generic Simulation Kernel, which includes• a language to define new modeling components • a graphical user interface

> A Library of ECLSS components implemented using the language.

INTRODUCTION (2)INTRODUCTION (2)

EcosimPro is not limited to ECLSS simulation and it is being applied to other simulation fields:

> Hydraulic and pneumatic circuits> Simulation of Space Propulsion systems> Simulation of Aircraft Gas Turbines> Chemical process> Electrical power plant cycles (Steam Cycle and Combined Gas

Cycle)

ECOSIMPRO HISTORY ECOSIMPRO HISTORY

Version 3.0 (December-1999) was the first commercial version for PC- windows.

There is a continuous development effort to produce upgraded versions:

Latest release:

> Version 3.3 (March-2004)

Future releases:> Version 3.4 (December 2004)> Version 4.0 (expected by 2005)

ECOSIMPRO LATEST IMPROVEMENTS ECOSIMPRO LATEST IMPROVEMENTS (1)(1)

The major differences between version 3.3 and previous version 3.2 are:

> a new graphical model builder, EcoDiagram

> new connection between EcosimPro and Excel, which is very easy to use

> upgraded ECLSS library with new components

> multiple language improvements

New connection EcosimPro-Excel

> Connection between EcosimPro and Excel enables to deliver EcosimPro models that can be run by system engineers without any EcosimPro knowledge

> Previous connection between EcosimPro models needed Visual Basic programming to manage the EcosimPro model object

> An Excel Add-In has been designed that enables to link Excel cells to EcosimPro model variables only by selection in graphical menus.

EcosimPro Future ImprovementsEcosimPro Future Improvements

Ecosim Version 3.4 shall be released in December 2004. Major changes from an users view point:

> It shall have an optimization module callable from the experiments

> A pre-processor with “Include” and “Macro”, PDE’s easily modelled using the Macro

> Multiple functions to read tables in different formats

EcosimPro Future ImprovementsEcosimPro Future Improvements

Ecosim Version 4 shall be released by the end of 2005

> Current EcosimPro version runs only in PC-windows, although it can generate model executables that run under Windows, Linux & Unix

• The graphical user interface was designed using Visual Basic and C++

> EcosimPro version 4.0 shall be multiplatform software running on Linux and Windows:

• EcosimPro Graphical User Interface is being redesigned using Qt

EXAMPLES (1)EXAMPLES (1)

An EcosimPro model of a cooling loop of an spacecraft has been built. The main features of the loop are:

> Mechanically pumped (COF pump)

> Single phase

> Working fluid is a design variable (the coolant can be selected between a set of predefined coolants)

> Thermal power to dissipate is 6000 W
