Abstract: Targeting gas analysis test in the aeroengine and combustion chamber experiments, the principle and system of gas analysis test were introduced. The computing method for Liquid fuel used was optimized, and the method for gas fuel was developed. The influence of the error about gas component test on the computation result of combusting parameter was analyzed. The effects of mixed sampling means and sampler structure were discussed, and the factors about judging rationality of mixed sampler structure were provided. The measurement results of gas analysis and general testing were compared. Excess air coefficient is better than 5% with reasonable mixed sampler structure and enough measuring points and reasonable gas analysis system. The deviation of combustion efficiency from thermocouple and gas analysis is analyzed.
