Abstract

The issues related to the study of the possibilities of automatic thrust control of turbofan engines (TFEs) in the powerplant (PP) of a twin-engine aircraft in flight are considered. The aim of this study is to formalize criteria for the multiparametric selection of turbofan pairs for powerplants of twin–engine aircraft and to develop the structure of the automatic control system for such installations to reduce the thrust asymmetry of their engines in flight. In the research, mathematical and software modeling are used. As a result of the study, the criteria for the multiparametric selection of pairs of such engines for twin-engine powerplants have been formalized for three thrust parameters of turbofan engines of the same series at once and the structure of the automatic control system of the powerplant of a twin-engine aircraft to eliminate the thrust asymmetry of its engines in flight has been developed.
