Abstract

Supersonic non-isobaric jet outflow was studied under conditions of interaction with the slipstream. Multilevel mathematical model was compiled making it possible to analyze structure of the gas-dynamic flow in the vicinity of the nozzle channel central body at the aircraft take-off path (0...10 km). Multilevel approach to calculating thrust parameters of the nozzle channel with central body requires development of a physical and mathematical model of the non-stationary interdependent processes that characterize operation of the “aircraft – nozzle cluster – jet” system as a whole. At the same time, it is necessary to form mathematical models of the processes for different degrees of the task detailing, i.e. within each scale of the task (micro-, meso- and macro-scale). Mathematical model includes calculation of the aircraft traction characteristics, study of the interaction features between the jet, the central body and the slipstream.
