Abstract
A hybrid electric gas turbine engine is provided. The hybrid electric gas turbine engine includes: a turbomachine having a compressor section and a turbine section arranged in serial flow order, the compressor section and turbine section together defining a core air flowpath, the turbomachine defining a core air flowpath exhaust; and an electric machine assembly having an electric machine disposed aft of the core air flowpath exhaust and mechanically connected to the turbine section.
Claims13
A hybrid electric gas turbine engine assembly, comprising:
- a gas turbine engine comprising a fan section and a turbomachine disposed aft of the fan section,
- the turbomachine comprising a compressor section and a turbine section arranged in serial flow order,
- the compressor section and turbine section together defining a core air flowpath,
- the turbomachine defining a core air flowpath exhaust,
- wherein the gas turbine engine defines a bypass airflow passage extending over the turbomachine, and
- wherein the gas turbine engine provides a bypass airflow through the bypass airflow passage;
- an electric machine assembly comprising an electric machine disposed aft of the core air flowpath exhaust and mechanically connected to the turbine section;
- an aft airflow passage defined between an electric machine housing of the electric machine and an electric machine assembly housing of the electric machine assembly,
- wherein combustion gasses are provided through the core air flowpath exhaust as a core exhaust airflow, and
- wherein the core exhaust airflow and the bypass airflow merge into the aft airflow passage;
- and
- at least one support disposed in the aft airflow passage and connecting the electric machine to the electric machine assembly housing, the at least one support located aft of the turbomachine.
