A short test series was run on the Mascotte cryogenic test facility of Onera, with the objective to demonstrate the feasibility of applying several diagnostics to the characterization of liquid oxygen/methane combustion in the range of low mixture ratios typical of gas generator operation. Tunable diode laser absorption spectroscopy and emission spectroscopy were used to investigate the gas mixture in the near injector region, while particle sampling was applied to the characterization of soot.
