Résumé

The information of the perspective application of cryogenic engineering and high temperature superconductivity aboard an aircraft equipped mainly with electric wires is cited. Technical and economic prerequisites of using cryogenic engineering aboard are examined. The history of development of aircrafts at cryogenic fuel in the A.N. Tupolev design engineering bureau is covered. The perspectives of using on­board cryogenic generators, cryogenic electric drives of compressors of air conditioning and pressure maintenance systems, hydraulic pumps drives, linear electric drives of control and autonomous drives of the undercarriage, distributive and transformer nodes as well as on­board power electric wiring on the base of materials with properties of high temperature superconductivity are envisaged. The ways of their using in on­board electric systems to protect the schemes, circuits and machines from the impact of electromagnetic fields at high intensity Meisner effect consisting in push­out of the external magnetic field from the superconductors’ volume were charted. A low temperature, a light load and low energy losses in electric machines will allow realizing all types of transformations at more high efficiency excluding unproductive losses such as heating and voltage drop.
