Abstract
An example system includes a throttle control for managing power in a hybrid propulsion system that includes an electrical propulsion unit configured to operate using electrical energy sourced from an electrical energy storage system (ESS) and/or one or more electrical generators, the throttle control comprising: a control lever movable through a plurality of positions, the plurality of positions including: a regeneration position; an off position; a maximum electric only position; a maximum continuous dual source position; and a maximum non-continuous dual source position.
Claims15
An airframe comprising:
- a plurality of electrical propulsion units configured to propel, via respective propulsors, the airframe using electrical energy sourced from an electrical energy storage system (ESS) and/or one or more electrical generators, the one or more electrical generators configured to operate using fuel;
- a display;
- and
- one or more processors configured to output, for display at the display, a graphical user interface (GUI) that indicates a respective operating state of each respective electrical propulsion unit of the plurality of electrical propulsion units, wherein the indication of the operating state indicates, for each respective electrical propulsion unit:
- a respective amount of torque provided by the respective electrical propulsion unit, and
- a respective representation of a source of electrical power used by the respective electrical propulsion unit to provide the respective amount of torque, wherein the representation of the source of electrical power indicates an amount of electrical power sourced by the respective electrical propulsion unit from the one or more electrical generators relative to an amount of electrical power sourced by the respective electrical propulsion unit from the ESS.
A system comprising a plurality of electrical propulsion units configured to propel an airframe using electrical energy sourced from an electrical energy storage system (ESS) and/or one or more electrical generators that operate using fuel, the system further comprising:
- a display;
- and
- one or more processors configured to output, for display at the display, a graphical user interface (GUI) that indicates a respective operating state of each respective electrical propulsion unit of the plurality of electrical propulsion units, wherein the indication of the operating state indicates, for each respective electrical propulsion unit:
- a respective amount of torque provided by the respective electrical propulsion unit, and
- a respective representation of a source of electrical power used by the respective electrical propulsion unit, wherein the respective representation of the source of electrical power indicates an amount of electrical power sourced by the respective electrical propulsion unit from the one or more electrical generators relative to an amount of electrical power sourced by the respective electrical propulsion unit from the ESS.
A non-transitory computer-readable storage medium storing instructions that, when executed, cause one or more processors of an aircraft to:
- control a plurality of electrical propulsion units of the aircraft to propel, via respective propulsors, the aircraft using electrical energy sourced from an electrical energy storage system (ESS) and/or one or more electrical generators, the one or more electrical generators configured to operate using fuel;
- and
- output, for display, a graphical user interface (GUI) that indicates a respective operating state of each respective electrical propulsion unit of the plurality of electrical propulsion units, wherein the indication of the operating state indicates, for each respective electrical propulsion unit:
- a respective amount of torque provided by the respective electrical propulsion unit, and
- a respective representation of a source of electrical power used by the respective electrical propulsion unit to provide the respective amount of torque, wherein the respective representation of the source of electrical power indicates an amount of electrical power sourced by the respective electrical propulsion unit from the one or more electrical generators relative to an amount of electrical power sourced by the respective electrical propulsion unit from the ESS.
