Patent abstract
A jet engine includes a fan arranged upstream of a core engine having a low pressure compressor, a high pressure compressor, a combustion chamber, a high pressure turbine, and a low pressure turbine. The high pressure turbine is drive-connected to the high pressure compressor. The low pressure turbine is drive-connected through a transmission to the low pressure compressor and to the fan, which are respectively driven in opposite rotation directions. A compressor disk of the low pressure compressor is positioned downstream directly after the fan so that a hub end section of the fan and the compressor disk together form a counter-rotating compressor stage.
