Abstract
In this study, the performance analysis of the engine was carried out according to the parameters determined by parametric cycle analysis in turbofan engines with afterburner and separate exhaust streams. The main purpose of the study is to determine the relationship between engine performance values, design parameters and flight ambient values. For this, the effects of Mach number, compressor pressure ratio and bypass ratio values on specific thrust, fuel-air ratio, specific fuel consumption and engine efficiency were investigated. The open source code PYTHON programming language was used in the study and the results were presented as graphically. Results consistent with the studies in the literature were obtained. According to the results, it was observed that the specific thrust values and the total efficiency values increased with the increase of the Mach number. On the other hand, with the increase of the Mach number, the fuel-air ratio decreased and more fuel consumption was required to provide the required thrust value. In the case of afterburning, as the bypass ratio increases, the specific thrust value and the total efficiency value decrease, whereas the specific fuel consumption of turbofan engines without afterburning increases.
