  • Perform trade off studies and plan the technical roadmap for thrust chamber assemblies of pump fed, liquid propellant engines.
  • Create thrust chamber subcomponent models and validate them against test data.
  • Perform detailed injection, combustion and cooling CFD studies to assess injector and cooling channel designs.
  • Plan and execute subcomponent and integrated engine test campaigns, and analyse the data gathered.
