Assessment and improvement of rationality methods of modern aircraft engines design and technological solution

Abstract

The results of the research of modern aircraft life cycle structure are presented. The basic principle of a life cycle system creations is cost minimization requirement of whole aircraft and the components from designing to disposal. The proposed model is based on the analysis of life cycle aircraft by elementary components.

Research on Intelligent Design of Geometric Factor Encoding for Aircraft Engine Turbine Structures

“…Aircraft engines are a key product in the development of the aviation industry, and the quality of engines directly determines the performance of aircraft. Moreover, the progress of engine development is also a decisive factor in the overall progress of aircraft development [5,6]. In the field of aviation engine turbocharging, the turbine operates at high temperatures and speeds, and the working conditions are extremely demanding, requiring a long lifespan and high reliability, while the quality is strictly controlled.…”

Investigation of typical damage to aircraft gas turbine engines type SAM 146

“…Основными повреждениями деталей приводов являются неравномерный или повышенный износ, выкрашивание или отслаивание материала поверхности контакта, локальный перегрев, попадание стружки или других твѐрдых частиц в каналы или на трущиеся поверхности [5,6]. Выкрашивание материала поверхностей контакта происходит в результате действия высоких контактных напряжений в тонком поверхностном слое зубьев, приводящих к подслойным разрушениям.…”
