    Increase resource of wing high lift devices of aircrafts of high-strength steels
    (National Aviation University, 2022-11) Kostianets, illia; Костянець, Ілля
    Ensuring of the high figures of wearability and durability of friction details is one of the major factors of reliability increasing and increasing of modern machines life cycle. Statistics shows that about 80 % of failures in the machines work occur as the result of wear and destruction of friction surfaces of machines details. Wear leads to the decreasing of the products functional qualities and to the loss of their consumer value. Increasing of products wearability contribute both and applying of materials with the high wear resistance, and design decisions, ensuring the compensation of wear, redundancy of wearability, common improving of friction conditions (using of high quality lubricants, protection from the abrasive influence, for example: welding deposition, thermal spraying, metallization and others). Wear can be considered as the mechanical process, complicated by the actions of physical and chemical factors, which cause the durability decreasing of surface layer microvolumes. Due to the wear the shaped and sizes of the details are changed, it results in the increasing of gaps in the movable connections, disruption of fit density of immovable connections. At the detail wear limit occurrence, its further using is impossible, because of disruption of node or mechanism normal work that can result in accident.

    Measures to improve the fuel efficiency of power plants for long-range passenger airplanes
    (National Aviation University, 2022-11) Xiaoxing, Peng; Сяосін, Пен
    Explanatory note on diploma work “Measures to improve the fuel efficiency of power plants based on unified turbofan engines for long-range passenger airplanes”.Unified turbofan engine based on prototype CFM-56-7B. Introduction; Analysis of measures for aviation fuel consumptio n reducing; Projected turbofan engine designing; Labour precaution; Environment protection;Contribution to fuel consumption with micr o-circuit method of cooling; Analysis of engine functional systems; General conclusion. Airplane is an indispensable way of travel in our daily life ， which greatly shortens our transportation time.In the case of the aircraft itself ， fuel efficiency has always been a concern for designers and airlines. Analyzing the fuel efficiency of the air transport industry and its influencing factors has important practical significance for the air transport industry to achieve green and low-carbon development and reduce aviation carbon emissions and fuel costs.
