Abstract:
The main aspects of the general task of integrating an aviation engine (AE) with a turbofan additional unit (TAU) of a multi-mode aircraft are the selection of the scheme and design parameters of the AE with the TAU (including parameters of the work process), as well as methods and means of automatic control of the AE with the TAU for better matching its characteristics with certain flight modes. These two tasks are closely interrelated: on the one hand, when determining the appearance of the aircraft and its power plant (PP), it is necessary to consider what means will ensure the adaptation o

Abstract:
The subject of this study is the estimation of non-measurable parameters of a gas turbine engine's operating process based on a limited set of measured parameters. The relevance of this research arises from the practical impossibility of measuring several critical engine parameters under operating conditions, such as thrust, turbine inlet gas temperature, among others, which are essential for control and diagnostics tasks. These parameters must be continuously estimated using only limited available data. This requires the use of a mathematical model of the engine's operating process, with cons

Long-term static strength is one of the most important parameters to be calculated at the life-time design stage of aircraft engine turbine blades. The importance of studying and modeling this parameter is based on many factors. In particular, it should be noted that one of these factors is the peculiarities of the anisotropic characteristics of single-crystal turbine blades made of nickel heat-resistant alloys for a wide temperature and power load range. Another important factor is the different crystallographic orientations of the single crystals. The analysis of the literature has shown tha

It is shown that the problem of aviation noise affecting the population near airports is still relevant. Pollution from aircraft noise is not a less influential factor than air or water pollution. The international community is paying close attention to tackling aviation noise by introducing requirements and noise limits for aircraft under development or in operation. Among the sources of aircraft noise, one of the main sources that should be singled out - the noise generated by gas turbine engines. Among the sources of noise of gas turbine engines should be noted to highlight the noise of the
