We examine two configurations for parallel hybrid electric aircraft, onewith, and one without, a mechanical connection between the engines and theelectric motors. For this two designs, we then review the power allocationproblem in the context of aircraft energy management for a 19-seat conceptualHybrid Electric Aircraft. We then represent the original optimal controlproblem as a finite-dimensional optimization and validate the second-ordersufficient conditions for global optimality of the obtained solution. This isthen followed by a sensitivity analysis of the fuel consumption on the initialaircraft weight and flight endurance. Our simulation and theoretical resultsclarify the limited benefit of charging the battery in-flight for this class ofhybrid electric aircraft to reduce $CO_2$ emissions.
