Test Position M11.3

Test setup at test position M11.3
The M11.3 is used to investigate the combustion and conversion behavior of hybrid propellant combinations.
  

Area of application

  • Basic research for fuels and engines under atmospheric conditions
  • Research and development tests for small engines or components for propulsion systems at high altitudes
  • Electrical simulations of regenerative cooling in rocket thrust chambers (18 kW)

Test objects

  • Investigation of combustion chambers under atmospheric environmental conditions
  • Investigation of hybrid rockets (e.g. propellant regression; optically accessible chamber)
  • Investigation of the propellant
  • Injection, ignition, combustion behavior under vacuum conditions
  • Component tests (valves, heaters, electrolyzer,...)
  • Simulation of the reactive/inert atmosphere and ascent/descent
  • Thermal engine analysis under vacuum conditions
  • Vacuum tests for components (e.g. electrolyzer, valves, heating elements)
  • Option: Installation of a small H2/O2 air initiator (2.5 kg/s) for hypersonic tests
  • Electrochemical thrusters and combined thrust clusters (chemical+electrochemical)
  • Investigation of propellant in regenerative cooling systems

M11.3 conducts basic research into propellants and engines for satellite and orbital propulsion systems as well as air-breathing propulsion systems. The focus here is particularly on combustion behavior, stability tests and performance analysis. Smaller engines or propulsion components can be examined and tested under vacuum conditions. There is the option of converting the test bench to a small air heater, which allows tests to be carried out in a similar way to the M11.1. This alternative means that large oxidizer mass flows are available at the test position, which is why research on hybrid drives is predestined for this system.
