Presentation of papers of ESA Space Propulsion Conference 2022 held in ESTORIL

Some of the papers presented at the 8th International Conference on Space Propulsion Conference SP2022 organised by ESA in Estoril in 2022 (9th-12th May) are now available at the  Papers > Space section in this website.

These articles show real projects carried out by companies such as DLR, Thales Alenia, OHB, Ariane Group, GomSpace, Airbus Defence and Space, ESA, etc. in space propulsion projects.

Today more than 50 companies in Europe use EcosimPro-ESPSS for space propulsion system simulation and it has become the reference tool in Europe for this type of studies. Just to mention a few examples, some of the projects are listed in the following paragraphs.

  • Thales Alenia UK has used EcosimPro for the Gateway project for the calibration of the Bipropellant Transfer Subsystem (BTS) . Gateway will be an orbiting lunar outpost supporting the long-term human return to the surface of the Moon and providing a staging point for deep space exploration. It is a critical component to NASA’s Artemis program.
  • Ariane Group has worked in a project related to the James Webb Space Telescope for avoiding a random uncontrolled re-entry on Earth or a collision with the valuable telescope, they have been working to perform an “extra-push sequence”. To validate the use of ESC-D and HM7B engines, a model in EcosimPro and Cathare tools was developed to predict the needed thrust domain avoiding the risks of random re-entry or collision.
  • GomSpace from Sweden has presented a paper about an innovative miniaturized cold gas propulsion module based on Micro-Electro-Mechanical Systems (MEMS) technology is currently being developed at GomSpace Sweden. The modelling of the propulsion system as a transient model in EcosimPro is performed to verify the fluidic conditions inside the system incling thermal and control systems.
  • DLR Bremen presented a paper about FROST, that it is a mission dedicated to fly on the DLR CompactSat Bus. In order to analyze the LN2 chill-down and transfer behavior in micro gravity within the CTS and ETS, a 1D EcosimPro-ESPSS model was developed. This way, quick iterations of design parameters like pipe lengths, storage tank pressure, degree of subcooling, different valves and their influence on chill-down performance were evaluated.
  • Universities of Munchen and Darmstadt in Germany presented a work about the application of Water Electrolysis Propulsion to a 3U CubeSat as a de-orbiting kit with attitude control. Liquid water is decomposed into gaseous hydrogen and oxygen by an electrolysis unit supplied by solar power. The simulation was done in ESPSS and it makes use of 1D gas dynamics simulation as well as chemical equilibrium assumption for combustion.
  • OHB Bremen presented a paper using EcosimPro-ESPSS that it models the transient phenomena experienced in bi-propellant propulsion systems at multiple scales for ExoMars. This study is used to define OHB propulsion guidelines for future missions (i.e. moon landers), in which more powerful propulsion systems will play a main role. Priming and water hammer cases were simulated on ESPSS and validated against experimental data.

These are just a few examples of the more than 20 papers of the Conference that used EcosimPro-ESPSS. We invite you to read these papers from our website.
