ARIS (ARIS – Akademische Raumfahrt Initiative Schweiz) finished two projects related to liquid propulsion.

  • LEA, building and testing a mobile test stand for liquid rocket engines up 1.5 kN. It was successfully tested with an Ethanol/N2O firing. This was a project with volunteers of ARIS members.
  • PROMETHEUS, a ETH focus project with the aim to modify the LEA test trailer for usage with liquid oxygen. Design and testing a regeneratively cooled 700 N engine.

On both projects our Bruno Berger acted as an advisor. Unfortunately the contract with ETH ended this this year, so it might be the last project we are involved in. Nevertheless, the last years with the students of ETH/ARIS were extremely inspiring and cool!
