A lever for adjusting output of a hybrid-electric powerplant of an aircraft includes a lever configured to move over an overall range of positions. Movement of the lever adjusts the output of the hybrid-electric powerplant between at least two modes of operation. In a first subset of positions within the overall range of positions, the hybrid electric powerplant is configured to operate an engine having a mechanical output, output first electrical energy from a motor/generator driven by the mechanical output of the engine, and drive a propulsion mechanism by the mechanical output of the engine. In a second subset of positions within the overall range of positions, the hybrid electric powerplant is configured to operate the engine having the mechanical output, receive second electrical energy at the motor/generator, drive the mechanical output with the motor/generator using the second electrical energy, and drive the propulsion mechanism by the mechanical output.

A method of and system for operating a hybrid electric propulsion system for an aircraft in a start sequence is provided. The hybrid electric propulsion system includes a thermal engine, an electric motor, a gearbox, an electric power storage unit, and a propulsion unit having a propeller having propeller blades. The method includes: driving the propeller from a static state to a target rotational speed within a predetermined range of speeds using the electric motor; transitioning the propeller blades from a feathered mode to an unfeathered mode while the propeller is being driven at the target rotational speed solely by the electric motor; starting the thermal engine; and transitioning the driving of the propeller using the electric motor to driving the propeller using the thermal engine.

An aircraft turbine engine includes a gas generator and a fan arranged upstream from the gas generator and configured to generate a main gas flow, one portion of which flows in a flow path of the gas generator to form a primary flow, and another portion of which flows in a flow path around the gas generator to form a secondary flow. The gas generator has a low-pressure body with a rotor driving the fan and a low-pressure compressor situated upstream from an intermediate housing. The turbine engine also includes an electric machine, mounted coaxially downstream from the fan and upstream from the intermediate housing. An intermediate shaft is driven by the rotor of the low-pressure body and drives rotors of the electric machine and of the low-pressure compressor.
