“…To determine the analytical solution for the problem, the armature winding can be replaced by an equivalent current layer at the bore diameter. In particular, this approach was used in the studies of electrical machines with bulk HTS elements [1,2] and HTS windings [3,4,7]. It is possible to use the superposition of the fields created by the currents in excitation and armature windings with the assumption of the constancy of relative magnetic permeability in ferromagnetic sections.…”

In this paper, a fully HTS salient-pole electrical machine with a ferromagnetic core is considered. Analytical expressions for main parameters of the machine are obtained based on the solution of the Puasson's equation for vector magnetic potential. Obtained solution takes into account dimensions of active zone, HTS tape's properties, especially relative permeability. Streszczenie.

“…Useful superconducting power devices, especially electric machines, have been developed, in particular for producing strong dc magnetic fields [3,4,12]. But such machines have only field HTS coils and copper armature coils and their specific power is not high enough for application at the aircraft.…”

“…Our experience in the field of HTS electrical machines shows that racetrack coils ( Fig. 1) are the only way to use modern HTS tapes as windings [3,7]. Therefore principal scheme of fully HTS machine is the scheme with racetrack coils on stator and rotor ( fig.…”

“…To compare two types of the machine we used equal initial parameters such as phase voltage U=1000 V and rotational speed n=2500 rpm. According to several research [3,7] critical current of HTS coil is lower than of HTS tape in self-field. Besides dimensions of HTS coil should be optimised to provide maximum magnetic flux and minimum magnetic inductivity in the area of the coil.…”

Nowadays More Electric Aircraft is already flying. The next step is development of all-electric airplane with fully new propulsion system. One of the key parameters of electric propulsion system is the specific power. Electrical machines are major components of such system. Therefore we need to increase the specific power of electrical machines. The usage of superconductivity allows to increase efficiency and power-to-weight ratio of all electrical systems of the aircraft. This work reviews potential specific power values of fully superconducting machines. Streszczenie. Maszyny elektryczne są ważnym komponentem w lotnictwie. Zastosowanie w nich materiałów nadprzewodnikowych pozwala na znaczące zmniejszenie stosunku mocy do wagi. Elektryczne maszyny nadprzewodnikowe o dużej mocy

“…At present, various projects of HTS electrical machines are known [17,18]. In particular, at the Moscow Aviation Institute (MAI), machines with HTS rotor windings and copper stator windings were made, as well as fully superconducting machines [19][20][21][22][23]. However, the literature offers scarce data on the design, creation, and study of systems including various HTS devices.…”

The paper presents a brief analysis of current achievements and key issues in the field of heat transfer and critical heat flux enhancement during boiling of cryogenic liquids and freons under various heat release laws via micro-structuring of the heat-generating surface. A review of new experimental data on the efficiency of heat transfer and critical heat flux enhancement during pool boiling via new micro-structured capillary-porous coatings created by plasma sputtering and selective laser melting/sintering (3D printing) is presented. The results of analysis of the efficiency of heat transfer and critical heat flux during boiling on heat-generating surfaces with micro-textures of different shapes and micro-profiling created by micro-deforming cutting are presented. New results obtained during nitrogen boiling under various hydrodynamical conditions on the mechanisms of sharp increase in the rate of non-stationary cooling of plates with new structured capillary-porous or low-heat-conductivity coatings with certain parameters are discussed. New results on the degree of heat transfer enhancement during boiling of liquids on micro-structured surfaces modified by the method of micro-arc oxidation are presented.
