Abstract: A reduction gearbox which has: an input, which can be coupled to an input shaft, which has an input speed; an output, which rotates at an output speed that is lower than the input speed; and at least one statically arranged component. It is envisaged that an electric generator is integrated into the reduction gearbox, said generator comprising a rotor and a stator, wherein the rotor of the electric generator is coupled to the output of the reduction gearbox, and the stator of the electric generator is coupled to a statically arranged component of the reduction gearbox.

Abstract: A supersonic gas turbine engine for an aircraft that comprises a nacelle, a fan, an engine core including a primary duct configured to guide a core airflow through the engine core, a bypass duct extending between the engine core and an engine casing and configured to guide a bypass airflow through the bypass duct, an intake located upstream of the fan, and a tertiary airflow duct extending between the engine casing and the nacelle and configured to guide a tertiary airflow. The intake is configured to extract air from the intake and guide it to the tertiary airflow duct in which the extracted air flows as tertiary airflow. It is provided that at least one heat exchanger is mounted in the tertiary airflow duct.
