- The turbofan with mixer engine model sensitivity of the thermal-flow processes effectiveness in the engine components changes was analyzed. The model of turbofan engine with the mixed exhaust stream is so complicated to use the small deviation methods to solve this problem. On that reason the own author methods to analyze this problem was proposed. During investigation it was revealed that the changes of some processes effectiveness leads to change of pressure inflow to the mixer and this cause to change of mixer process effectiveness. The mixer pressure drop coefficient decries so slightly but it should be taking into consideration during exact calculations. In the main parts of paper the results of simulation of engine work parameters sensitivity of the thermal-flow processes effectiveness changes is presented and discussed. The specific thrust and specific fuel consumption were chosen as the engine work parameters. The model responds for change of internal process effectiveness in all range and for small step was analyzed. The conclusions are presented in final parts of the paper. The essential influence on relations between the change of the efficiency of rotor sets and with specific parameters has compression rate of compressor. Generally the improvement performers of the excellence processes give better effects at the lower temperature value in front of the turbine.
