EcosimPro/ESPSS can be used to model propulsion systems for spacecraft and satellites, including priming processes, engine startup, simulation of fuel tanks, heat exchangers, mechanical systems and electronic pressure regulators. Therefore it can model any type liquid rocket engine cycle with one or more combustion chambers, including turbo-machinery (pumps, compressors and turbines) and cooling systems with two-phase fluids.
The new improvements to the European Space Propulsion System Simulation platform (ESPSS) developed for the ESA by an EA-led consortium were presented at this forum. New items are the new modules for electric propulsion and solid/hybrid propulsion, a new library for stationary calculations, new solid/liquid and ramjet/scramjet fuel combustors and a new library for calculating orbits.
EcosimPro/ESPSS is currently being used by numerous European companies for designing new space propulsion systems. Many of the papers presented here, available on our website, included models developed with this software, demonstrating its real use in current projects now underway such as Exomars, Ariane, MPS Constellation, etc.
On the last day of the fair, the ESA organized the third workshop for EcosimPro/ESPSS users, with a strong turnout from representatives from the European space industry. There, papers were given on work done in the industry and there was a round table held to propose new improvements to the tool in the future. A new ESPSS development phase called Multiphase Flow Modelling, more detailed information on which will be later provided, will also be headed by EA.
