Test Position M11.1

Air heater test bench on the M11.1
The air heater at M11.1 is used to generate hot flows at high speed, high pressure and high mass flow. Research is being conducted here on supersonic and hypersonic drives.
Research channel at M11.1
Cooling methods for rocket engines are investigated within this research channel. Optical measurement methods are used to visualize the flow.

  • ramjet systems
  • SCRamjet systems
  • Subsonic/supersonic combustion (injection and ignition)
  • Cooling tests (e.g. film cooling, transpiration cooling)
  • Nozzle flow tests

Test position M11.1 is equipped with a hydrogen-oxygen air heater to simulate scram and ramjet conditions. The air heater generates a mass flow of up to 5 kilograms per second of hot air at a total temperature of 1500 Kelvin. Investigations into the film cooling of rocket engines are currently being carried out at M11.1 together with the European Space Agency ESA, ArianeGroup and the VKI.
