Abstract
A power distribution circuit for an electrically powered aircraft includes a plurality of batteries and a plurality of electric propulsion systems. A plurality of isolated power distribution circuits each couple a battery of the plurality of batteries to two or more electric propulsion systems. The plurality of electric propulsion systems are positioned on the aircraft to apply balanced forces to the aircraft such that in the event of a failure, the aircraft remains stable and only experiences a loss in altitude or speed.
Claims20
An electrically powered aircraft comprising:
- a first propulsion system comprising a first propeller, a first drive shaft drivingly coupled to the first propeller, a first primary winding configured for rotating the first drive shaft, and a first redundant winding configured for rotating the first drive shaft;
- a second propulsion system comprising a second propeller, a second drive shaft drivingly coupled to the second propeller, a second primary winding configured for rotating the second drive shaft, and a second redundant winding configured for rotating the second drive shaft;
- a third propulsion system comprising a third propeller, a third drive shaft drivingly coupled to the third propeller, a third primary winding configured for rotating the third drive shaft, and a third redundant winding configured for rotating the third drive shaft;
- a fourth propulsion system comprising a fourth propeller, a fourth drive shaft drivingly coupled to the fourth propeller, a fourth primary winding configured for rotating the fourth drive shaft, and a fourth redundant winding configured for rotating the fourth drive shaft;
- a first battery;
- a second battery;
- a first power distribution circuit configured to transfer electrical power from the first battery to the first primary winding and the fourth primary winding;
- a second power distribution circuit configured to transfer electrical power from the second battery to the second primary winding and the third primary winding;
- a third power distribution circuit configured to transfer electrical power from the first battery to the second redundant winding and the third redundant winding;
- and
- a fourth power distribution circuit configured to transfer electrical power from the second battery to the first redundant winding and the fourth redundant winding.
