Abstract
In one embodiment, a method includes determining a pitch value based on at least an energy goal. The energy goal may be at least one of bowed rotor motoring or an engine start. The method includes adjusting a pitch of a plurality of variable-pitch propeller blades based on the pitch value. The plurality of variable-pitch propeller blades are part of a variable-pitch propeller. The method includes, in response to a rotation of the plurality of variable-pitch propeller blades about a central axis based on the pitch of the plurality of variable-pitch propeller blades, activating an electric brake to reduce a speed of the rotation. The method further includes transferring electrical energy, generated by the electric brake reducing the speed of the rotation, to a component.
