Item 2.1.3 Інформаційні технології в авіації(2021-05-11) Копилов, Станіслав Володимирович; Бондік, Олександр СергійовичItem A novel algorithm for damage analysis of fatigue sensor by surface deformation relief parameters(2013-05) Konovalenko, I.; Maruschak, P.; Menou, A.; Karuskevich, M.; Ignatovich, S.Fatigue damage of metal structures may be estimated by the application of sensors with the surface relief pattern indicating the accumulated fatigue damage. The nature of the deformation relief has been investigated. Digital analysis of the surface patterns based algorithm for the integral evaluation method has proved the efficiency of integral parameters (the general area of damage, mean gradient along the coordinate axes, and the mean amplitude of the histogram function spectrum) application for additional quantitative description of such surface structures. The evolution of deformation relief parameters on the sensors surface is determined by the process of the sensor and construction fatigue damage accumulation.Item A study of the energy balance of main gas pipeline operating modes on its efficiency(Національний авіаційний університет, 2022-10-07) Kapitanchuk, Kostiantyn; Andriyishyn, Mykhailo; Pikul, Marina; Otroshchenko, Volodymyr; Капітанчук, Костянтин Іванович; Андріїшин, Михайло Петрович; Пікуль, Марина Олександрівна; Отрощенко, Володимир ВіталійовичA study of the efficiency of the main gas pipeline «Soyuz» in different modes with the corresponding daily productivity and the effect of compressor stations shutdowns were conducted.

М.; Тегеshсhепkо, Yu.Yu.; Kushchinskiy, А. О.Рurpоsе. Comparative evaluation of aeroacoustic characteristics of the axial соmрrеssоr stages with а single and equivalent tandem impeller. Methodolory. The rеsеагсh was реrfоrmеd using the пumегiсаl ехреrimепt. The flow рагаmеtеrs in the stage of the axial соmрrеssоr wеrе calculated by solving the. non-stationary system of Navier - Stokes equations. The equations were closed bу the model of tuгbulеnt viscosity SST. The stage of the соmрrеssоr consisted of inlet guide vanes, the impeller and the guide vanes. The imреllег of the modified axial соmрrеssоr stage is designed as an equivalent tandem rоw. Acoustic sоurсеs of the axial соmрrеssог stage were calculated using the Ffowcs Williams - Hawkings equation. Findings. The гesults of а соmрагаtive eva]uation of the aeroacoustic characteristics of the axial соmрrеssог stages with а singlе and equivalent dоublе-гоw imреllеr аге оbtаinеd. The use of а tandem rоw instead of an equivalent single гоw in the impelle of the axial соmрrеssог slage makes it possible to increase the рrеssurе гаtiо bу 1-I5 % . In the design mode, the pressure ratio is inсгеsеd bу 8.5 %. А stage with а tandem impeller has grеаtеr acoustic efficiency than а соmрrеssоr stage with а single impeller. The obtained гesults dеmопstгаtе а significant decrease in the acoustic рrеssurе of the dipole sоurсе. In the design mode, the acoustic ргеssurе of the dipole sоurсе decreases bу mоrе than 70 %, the acoustic рrеssurе of the quadrupole sоurсе dесгеаsеs bу mоrе than 10 %. Originality. Fоr the first time the results of а comprehensive study of the aerodynamic and acoustic characteristics of the axial соmрrеssоr stage wеrе obtained. The results allow estimating the efficiency of application of tandem rоw in the impeller of the low loaded subsonic stage of the ахiаl соmрrеssоr. Practical value. The received recommendations can bе used while designing imреllеr machines with а low lечеl of acoustic emissionItem Aerodrome professional practices : self-study method guide .

Theoretical dependencies for an ideal gas(National Aviation University, 2019-03-01) Goncharenko, Andriy ViktorovichAn equation that establishes (sets up) the connection between pressure, temperature, and specific volume of a medium of a constant content (composition, compound) is called the thermodynamic equation of stateItem Aircraft engines. Lecture notes (first preliminary edition). Chapter 4. Approaches for a real gas dependencies derivation(National Aviation University, 2019-03-01) Goncharenko, Andriy ViktorovichThus, the properties of real gases in both quantitative and qualitative respects significantly differ from the properties of the ideal gasses. Therefore, all results for ideal gases will be approximate and fare just at the very great rarefactions. Accordingly to that there appeared (came out, emerged) a necessity in developing the equation of state, which would precisely describe the state of a real gas.Item Aircraft engines.
