Product sheet

Description

Why this name?

PROOSIS is an ancient Greek word (ΠΡΟΩΣΙΣ) that means Propulsion (pronounced as “pro·ow·suhs”). Also the acronym PROOSIS stands for PRopulsion Object Oriented SImulation Software.

What is PROOSIS?

PROOSIS is a standalone, multi‑platform, object‑oriented environment designed for high-fidelity simulation of gas turbine engines and integrated aerospace systems. As an extension of EcosimPro, it adds aeronautics-specific tools like performance map handling, multipoint design, and support for SAE-standard “customer decks”, etc.

Origins & Industry Adoption

Born from the EU’s FP6 VIVACE project and later enhanced under FP7 CRESCENDO, PROOSIS has been developed in collaboration with major aerospace firms in Europe. Since its industrial launch in 2008, it has become a leading tool for modeling advanced architectures, including open-rotor, H2 injection, APUs, etc.

Key features

  • Full Lifecycle Modelling

    Capable of steady-state, off‑design, and transient simulations, including multi‑point and dynamic scenarios. Also supports sensitivity studies, inequalities and optimization

  • TURBO Component Library

    Offers an extensive, customizable library (compressors, turbines, shafts, heat exchangers) built using object-oriented principles—drag-and-drop schematic modeling

    Check TURBO library

  • Control & Systems Integration

    Simulate gas turbines alongside control systems, ECS, electrical or fuel systems—and even full aircraft powerplants

  • Customer Deck Generation

    Export models as encrypted black-box modules conforming to SAE ARP4868 and AS4191 formats.

  • Solver and Optimization Tools

    Includes advanced solvers with algebraic and dynamic equations systems and optimization capabilities like differential evolution and SQP methods

  • External Connectivity

    Supports co-simulation with Simulink, Excel, FMI, OPC-UA,Python, etc.

Used by the industry

Some of the most important aeronautic companies in the world use PROOSIS for modelling aircraft systems (eg. propulsion, ECS, etc.)

System requirements

The minimum system requirements are the following:

  • Microsoft Windows 64 bits (11, 10)
  • 4GB RAM memory
  • 3GB of free disk space

 

Supported C++ compilers to run simulations:

  • Microsoft Visual Studio 2015-2022 (64 bits) on Windows
  • Microsoft Visual Studio 2010 (32 & 64 bits) on Windows
  • GNU gcc [gcc, g++, gfortran] compiler 11.2 and 4.9 (64 bits) on Windows
  • GNU gcc [gcc, g++, gfortran] compiler 4.8 (64 bits) on Linux (only simulations, not IDE).
