Abstract
A hybrid electric gas turbine engine includes a fan section having a fan, a turbine section having a turbine drivably connected to the fan through a main shaft that extends along a central longitudinal axis, a gas generating core extending along a first axis that is radially offset from the central longitudinal axis, and an electric motor drivably connected to the main shaft, wherein the electric motor is colinear with the main shaft.
Claims20
A hybrid electric gas turbine engine, comprising:
- a fan section having a fan;
- a turbine section having a turbine drivably connected to the fan through a main shaft that extends along a central longitudinal axis;
- a gas generating core extending along a first axis that is radially offset from the central longitudinal axis;
- and
- an electric motor drivably connected to the main shaft, wherein the electric motor is colinear with the main shaft.
A hybrid electric gas turbine engine, comprising:
- a fan section having a fan and a guide vane extending from a static structure;
- a turbine section having an exit housing and a turbine drivably connected to the fan through a main shaft that extends along a central longitudinal axis;
- a gas generating core extending along a first axis that is radially offset from the central longitudinal axis;
- and
- an electric motor drivably connected to the main shaft, the electric motor being radially offset from the gas generating core.
A method for assembling a hybrid electric gas turbine engine, comprising:
- coupling a fan section having a fan to a turbine section having an exit housing via a main shaft that extends along a central longitudinal axis, wherein the turbine section is drivably connected to the fan via the main shaft;
- coupling a gas generating core between a static structure of the fan section and the turbine section, wherein the gas generating core extends along a first axis that is radially offset from the central longitudinal axis;
- and
- coupling an electric motor to the main shaft, wherein the electric motor is colinear with the main shaft and drivably connected to the main shaft, the electric motor being radially offset from the gas generating core.
