Jet engine combustor parametric analyzes

The combustion processes specific to jet engines involve aerodynamic, thermodynamic, combustion chemistry and heat transfer aspects with implications on performance and environmental pollution reduction. The operating performances of a combustion chamber are influenced by two groups of parameters: atmospheric and operating. Depending on the constructive or operating limitations, a series of optimizations are adopted based on parametric pre-design analyses that can provide numerical data on the operating intervals of the combustion chamber in particular and of the jet engine in general. The article includes a series of parametric analyses on the combustion process, using the GasTurb software tool, to determine the degree of influence of relevant combustion parameters on the performance of jet engines.
