PROOSIS - Propulsion Object-Oriented Simulation Software

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

    A powerful, fully customizable library for aeronautical gas turbine performance: compressors, turbines, shafts, heat exchangers and more. Built on object-oriented principles, it enables fast drag-and-drop schematic modeling so you can design, analyze and optimize engine architectures with maximum agility.

  • ASYST Component Library

    A complete suite for cycle analysis and steady simulation of humid air systems, vapor cycles, hydraulic circuits and electric motors/generators in aircraft. ASYST helps you quickly evaluate concepts, improve energy efficiency and accelerate system development.

  • THRUST Component Library

    An advanced library for transient propulsion and fluid system simulation, covering volumes, heat exchangers, chemical reactors, tanks, pumps, compressors, turbines, actuators and more. THRUST lets you model, integrate and optimize complex propulsion architectures from concept to detailed design.

  • 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)
  • 8GB RAM memory
  • 3GB of free disk space

Supported C++ compilers to run simulations:

  • Microsoft Visual Studio 2017-2026 (64 bits) on Windows
  • Microsoft Visual Studio 2010 (32 & 64 bits) on Windows
  • GNU gcc [gcc, g++, gfortran] compiler 11.2 (64 bits) on Windows
  • GNU gcc [gcc, g++, gfortran] compiler 4.8 (64 bits) on Linux (only simulations, not IDE).
