Abstract

A study on the integration of the propulsion system of medium-range passenger aircraft has been performed. The architecture of the power plant system and the system approach to power plant design are considered. The block division of the solved problems is offered – connected with a choice of schemes and the basic design parameters of aircraft with its power plant and integration of management. The influence of the power plant and elements of the glider on the choice of parameters of the working process and the scheme of the engine at the technological and structural level is considered. The model of research of the principle of the dependence of characteristics of the movement of the passenger aircraft on a level of integration of characteristics of its power plant is considered. Based on this model, an algorithm for increasing the efficiency of integration of the propulsion system of medium-range passenger aircraft is proposed. The study focuses on the consideration of the aircraft as a complex and highly efficient system that contains subsystems and components. Accordingly, the subject area of the study has a multifaceted complex nature and is presented taking into account the technological evolution of air passenger traffic, which has already reached a fairly high degree of development of the existing system architecture. The approach to the integration of the characteristics of the propulsion system of passenger aircraft is reduced to a multifaceted systematic consideration of the ICAO requirements for passenger aircraft, as well as the requirements for their certification. Aspects of modern scientific researches that are carried out in the field of modeling of synthesis of integration of characteristics of a power plant and accordingly are developed taking into account technological and design decisions concerning the improvement of the general architecture of the system in a foreshortening system are considered. Based on the calculations of the developed algorithm, the results of integration modeling are presented within the aerodynamic design of a passenger aircraft, compressors, and turbines. The diagram of efficiency of integration of power plant of medium-range passenger planes is given. The study demonstrated that at the technological and structural level, a generalized-integrated consideration of the power plant and glider elements, respectively, affects the choice of operating process parameters and engine scheme.
