Claim 8:
9. The system of claim 1, further comprising:
a chassis defining a first power unit location and a second power unit location, wherein the primary electric motor, the rotor, the internal-combustion engine, the engine shroud, the cooling fan, and the local controller form a first power unit mounted to the chassis at the first power unit location; and
a second power unit mounted to the chassis at the second power unit location, the second power unit comprising:
a second primary electric motor comprising a second motor output;
a second rotor coupled to the second motor output and configured to generate a third thrust;
a second internal-combustion engine comprising a second cylinder head and a second output shaft coupled to the second rotor;
a second engine shroud defining a second shroud inlet between the second rotor and the second internal-combustion engine, extending over the second cylinder head, and defining a second shroud outlet opposite the second rotor;
a second cooling fan coupled to the second engine shroud and configured to displace air through the second engine shroud to cool the second cylinder head and output a fourth thrust, from the second shroud outlet, to augment the third thrust; and
a second local controller configured to:
access a second target total thrust based on a second flight command received from a primary flight controller of the aerial vehicle;
drive the second primary electric motor to selectively output torque to the second rotor or regeneratively brake the second rotor according to the second target total thrust.
