A numerical calculation of technological stresses in a threaded connection with the presence of a threaded insert made of corrosion-resistant heat-resistant steel 08H18N10 in the DEFORM-3D software package was performed. The influence of the change in the thread pitch on the distribution of axial, radial and tangential stresses is investigated. Analytical and numerical method calculated the distribution of the load on the threads in uniaxial tension in the connection “bolt-nut”. The stress-strain state of a threaded joint with the presence of a threaded insert for uniaxial tension was obtained. The effect of installing the threaded insert in the joint has been evaluated.

This paper is devoted to obtaining a mathematical model of the lithium-ion battery discharge capacity at a constant current discharge from the system of physical and chemical processes in a lithium-ion battery equations obtained earlier by the authors. The input of this model is the discharge capacity of a particular instance of a lithium-ion battery and a constant discharge current at which the discharge capacity is determined. The output of the model is determined by the discharge capacity of the considered instance of the lithium-ion battery. The model under consideration for the discharge capacities of a lithium-ion battery is obtained by excluding dynamic variables and unknown constant coefficients from the system of physical and chemical processes in lithium-ion battery equations. This exclusion of dynamic variables is carried out numerically by calculating different dynamics of physical and chemical processes in a lithium-ion battery corresponding to different values of constant coefficients and further approximation of the desired model on these calculated dynamics. The obtained model is tested experimentally.

Switched Reluctance Machine (SRM) is a very basic and simple electrical machine in structure with winding only at its stator. SRM has widely been considered for possible usages in modern aircrafts through the development of More Electric Aircraft (MEA). However, the nonlinear behavior of SRM results in difficulty in obtaining accurate model for simulation and development of its control system. A piecewise analytical modelling using inductance profile for a specific SRM is presented in this paper. The SRM used in this study is a specific custom designed 45kW 6/4 SRM which has unique electromagnetic characteristics. In this paper, the analytical model presented is compared against the measured values for accuracy.

High-torque permanent magnet synchronous electric motors are widely used in many industries due to their minimum weight and size parameters, at maximum torque, low vibrations and high efficiency. A special effect from the use of high-torque permanent magnet synchronous electric motors can be achieved in the aerospace industry as electric motors for various executive units, for example, a flaps drive, slats or elevators. One of the main problems in high-torque permanent magnet synchronous electric motors design is hysteresis and eddy currents losses. To minimize hysteresis and eddy current losses it is possible to use amorphous low-coercivity materials in high-torque permanent magnet synchronous electric motors magnetic cores. To assess the effectiveness of using amorphous low-coercivity materials, comparisons are made of high-torque permanent magnet synchronous electric motors with a magnetic core made from amorphous low-coercivity materials with a similar high-torque permanent magnet synchronous electric motors, whose magnetic core is made of electrotechnical steel. A multi-polar high-torque permanent magnet synchronous electric motors with a fractional toothed winding is considered. The studies results show the possibility of creating high-torque permanent magnet synchronous electric motors with magnetic cores from amorphous low-coercivity materials and the effectiveness of using amorphous low-coercivity materials in high-torque permanent magnet synchronous electric motors has been proven.

The article shows that the presence of impurities or oxidation products resulting from heating in insulation leads to leakage currents. The formula for calculating the power emitted by the active component of the leakage current is obtained. The basic mathematical model of thermal processes of a power cable line was refined by taking into account the values of internal heat sources. A mathematical model was obtained that allows calculating the power of partial discharges, as well as determining the location of the inclusion in the main insulation, due to the power of the active component of the leakage current, when it occurs in the main cable insulation. The calculation of the change in heat flux passing through the layers of cable insulation by the piecewise-specified functions method, taking into account the thermal resistance of the inclusion, is carried out. The mathematical model, along with the layer-by-layer calculation of isotherms in the cable section, makes it possible to determine the presence of inclusions in the insulating material and their influence on the temperature distribution profile at characteristic points of the cable section. The method proposed in the developed model makes it possible to account for heat losses based on the thermal and geometric dimensions of the inclusion. This will allow to obtain the temperature in all layers of the cable line, starting from the radial distances, inclusion parameters caused by the insulation core current, as the main temperature-forming factor.

The article developed a mathematical model for calculating the electromagnetic parameters of inductors of special types, for example, inductors with an intermediate conductive medium, inductors-transformers, inductors for heating cylindrical surfaces, when the length of the detail considerably exceeds the length of the inductor. As a result, analytical formulas were derived that allow calculating the parameters of the electromagnetic field and integral values depending on the axial coordinate and radius with a simultaneous analytical solution of a two-dimensional electromagnetic field for areas of the radius of the system from the axis of the inductor or detail to the internal radius of the inductor. The dependences obtained on the basis of the equation for the vector potential and the Bessel equations of zero and first order, which determine the influence of the geometric parameters of the inductor and the details on the magnetic field strength and specific power, are given. Cases of cylindrical coils with a specified number of turns, as well as coils in the form of thin or flat rings are considered. The results of calculations based on the created formulas are presented in the graphs of the distribution of electromagnetic parameters of the system “short inductor - long detail”.

This paper presents the design of a 150-kVA 24,000-rpm high-speed permanent-magnet generator for more electric aircrafts. The additional winding is introduced to operate the machine without high-performance inverters and is here demonstrated as an effective solution to increase the capabilities of the machine under fault and overload condition. Based on the calculations, a full-size experimental SG prototype with an additional winding located on the stator back was manufactured and tested. The experimental results are in good agreement with the computer simulation data, demonstrating the proposed technology and the additional functionalities within a power-to-mass ratio of 4 kW/kg.
