FIELD: engines and pumps. ^ SUBSTANCE: gas turbine engine comprises at least one turbo compressor rotor with labyrinth seal that runs in bearing and at least one electrical machine built in turbo compressor. Electrical machine comprises set of permanent magnets fitted on turbo compressor rotor, and electrical machine stator arranged on bearing support housing face surface and having its winding arranged on bearing support housing. Set of permanent magnets is fitted to axially move in collar arranged on turbo compressor rotor inner surface between stator winding. Aforesaid magnets are spring loaded in direction opposite electrical machine stator to rest against piston fitted inside collar circular chamber. Said circular chamber communicates, via channel, with turbo compressor air passage. ^ EFFECT: higher power output and efficiency. ^ 4 cl, 2 dwg |
