For the past 15 years, leading aerospace companies have relied on PROOSIS to model and analyse gas turbine performance. Its advanced capabilities support design, off-design and transient simulations, helping engineers streamline development, reduce testing requirements and reduce costs. With support for Beta and MFT performance maps, advanced solvers, configurable operating limits, custom fuel properties and very intutive graphical environment, PROOSIS provides the flexibility to tackle complex propulsion challenges.

Engineers can also deliver customer decks with protected models, enabling customers to run performance simulations while safeguarding proprietary knowledge.

PROOSIS, together with the TURBO, THRUST and ASYST toolkits, enables engineers to model conventional and advanced propulsion configurations—including turbofans, turbojets, open rotors, electric propulsion and hydrogen propulsion—under both steady-state and transient operating conditions. These capabilities extend to aircraft subsystems, including environmental control systems (ECS), fuel systems and electrical networks, supporting integrated analysis of propulsion and aircraft systems.
