Abstract
A power system for an aircraft comprises: a first motor-generator component; a second motor-generator component; a common shaft, wherein the first and second motor-generator components are connected to the common shaft in series; and a de-coupler operable to disconnect the first motor-generator component from the common shaft.
Claims20
A power system for an aircraft, the power system comprising:
- a first motor-generator component including a first drive shaft;
- a second motor-generator component including a second drive shaft;
- a common shaft, wherein the first and second motor-generator components are connected to the common shaft in series;
- and
- a de-coupler operable to disconnect the first drive shaft of the first motor-generator component from the common shaft, wherein the de-coupler comprises:
- a first torque coupler configured to selectively couple the first drive shaft of the first motor-generator component with the de-coupler;
- and
- a second torque coupler configured to couple the common shaft with the de-coupler.
