Analysis of methods of attachment of the turbofan on the aircraft wing and possible ways to solving mass problems

Abstract

In this paper, a comparative analysis of the external fastening of turbofan on the aircraft wing. The purpose of the study is: to compare the weight of the suspension system structure, currently being replaced for the turbofans, with preliminary strength calculations. This is characterized by two types of fastening of the engine structure – truss-ferment-beam. Solid-state models, finite element models and calculations of equivalent loads were constructed to analyze the mass characteristics of suspension systems. And the requirements for mounting the engine on the wing of the self-summer were also considered. As a result, the results of the study show that in this case, it is more rational to use a truss scheme in the design.
