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.

Hybrid propulsion system cockpit interface

A system includes a controller configured to monitor a fuel system supplying fuel to a gas turbine engine. The system also includes an electric propulsion system controlled by the controller. The electric propulsion system is configured as a variable load, which is supplied rotational energy by the engine. The controller is configured to dynamically control a magnitude of the variable load to adjust rotational speed of the gas turbine engine during a fixed level of fuel supply to the gas turbine engine. The electric propulsion system may include an electric generator and a plurality of propulsor motor(s) rotating a propulsor to provide thrust and/or lift to a vehicle such as an aircraft. The electric generator may be rotationally driven with the gas turbine engine to output electric power. The electric power is supplied to the propulsor motor(s) to rotate the propulsor to provide thrust and/or lift of the vehicle.
