Abstract
This disclosure describes at least embodiments of an aircraft monitoring system for an electric or hybrid airplane. The aircraft monitoring system can be constructed to enable the electric or hybrid aircraft to pass certification requirements relating to a safety risk analysis. The aircraft monitoring system can have different subsystems for monitoring and alerting of failures of components, such as a power source for powering an electric motor, of the electric or hybrid aircraft. The failures that pose a greater safety risk may be monitored and indicated by one or more subsystems without use of programmable components.
Claims21
A control system for a vehicle motor that includes a plurality of field coils, the control system including a controller configured to operate the vehicle motor to compensate for a failure of one or more of the plurality of field coils, the control system comprising:
- a memory device configured to store an operating parameter;
- a controller configured to increase, according to the operating parameter, a power input to one or more individual field coils of a plurality of field coils of a motor to compensate for a failure of one or more of the plurality of field coils, the plurality of field coils being configured to generate a torque on a rotor of the motor, the motor being supported by a housing and configured to propel the housing;
- and
- a sensor configured to detect the failure of the one or more of the plurality of field coils,
- wherein the controller is configured to no longer provide an electrical current to a first field coil of the plurality of field coils in response to detecting the failure of the first field coil.
A control system for a vehicle motor that includes a plurality of field coils, the control system including a controller configured to operate the vehicle motor to compensate for a failure of one or more of the plurality of field coils, the control system comprising:
- a memory device configured to store an operating parameter;
- and
- a controller configured to increase, according to the operating parameter, a power input to one or more individual field coils of a plurality of field coils of a motor to compensate for a failure of one or more of the plurality of field coils, the plurality of field coils being configured to generate a torque on a rotor of the motor, the motor being supported by a housing and configured to propel the housing,
- wherein the controller is configured to:
- prior to a failure of a first field coil of the plurality of field coils, provide an electrical current one time to all of the plurality of field coils in an order prior to providing the electrical current another time to any of the plurality of field coils, and
- subsequent to the failure of the first field coil, no longer provide the electrical current to the first field coil.
A method of operating a motor of a vehicle, the method comprising:
- supporting a motor by a housing;
- providing power input to individual field coils of a plurality of field coils of a motor to generate a torque on a rotor of the motor;
- propelling the housing by the motor;
- and
- increasing the power input provided to one or more of the individual field coils of the plurality of field coils to compensate for a failure of one or more of the plurality of field coils,
- wherein said increasing comprises, subsequent to the failure of a first field coil of the plurality of field coils, increasing an electrical current provided to at least two of the plurality of field coils to compensate for the failure of the first field coil.
