High-pressure Combustor Rig Stuttgart (HBK-S)

zum Bild HBK-S

The high-pressure combustor rig Stuttgart (HBK-S) is characterised by an excellent optical access for laser diagnostics. Sophisticated optical diagnostics together will classical measuring techniques allow the development of burner and combustion systems for gas turbines (stationary and aero engines).


  • Investigations of scaled (generic) burners and combustors at gas turbine relevant conditions
  • Excellent optical access for laser diagnostics
  • Numerous classical measuring techniques
  • Broad fuel spectrum (gaseous, liquid) available
