PROOSIS, Propulsion Object-Oriented Simulation Software
PROOSIS is a modelling and simulation environment for continuous 1D physical systems and discrete events aimed mainly at simulating aerospace propulsion systems.
It provides tools for conceptual design of an engine, facilitating the analysis of the impact of different configurations and preliminary dimensioning of equipment, mono-point and multi-point design, parametric studies, sensitivity analyses, customer deck generation, optimisation studies, multi-fluid models, maps handling, etc.
PROOSIS has all the simulation power of EcosimPro and adds a set of extra capabilities for modelling aeronautical gas turbines, some of which are:
- Sensitivity calculation wizard
- Wizard for creating design and off-design calculations. This is a powerful system-design tool that can be used in design studies in one or more workplaces
- Calculation with closed equations or inequalities: this makes it possible to incorporate equations in the form of constraints in the design calculations
- Calculation of engine steady states and transients
- Description of turbine machinery actuations by means of various kinds of actuation maps (eg BETA, MFT,etc)
- Plotting operating graphics on compressor or turbine actuation maps
- The TURBO library, which contains all the standard components of a gas turbine (compressors, turbines, fuel chambers, etc). All the components are configurable and have the source code of each so that users can transform them
- The ENGINE library, with several sample engine configurations based on the TURBO library
- A sophisticated Customer Deck tool for exporting models which enables the modeller to export simulation models as black boxes. Through a dialogue with the user, a model can be easily exported for re-use on different platforms without having to install PROOSIS. It uses ARP4868, which defines the API common to engine performance programs
PROOSIS keeps the multidisciplinary nature of EcosimPro by incorporating all its capabilities, so it models not only gas turbines, but also other systems such as mechanical systems, thermal systems, control systems, etc.
Any library or model that runs in EcosimPro also runs in PROOSIS, although models made in PROOSIS using the TURBO library can not be used in EcosimPro.
PROOSIS is being used in the aeronautical and space industry to design new gas turbines, new engine architectures, rocket engines, etc.
