Thanks to its typical limited speeds and altitudes, Urban Air Mobility represents
an interesting application for electric and hybrid-electric power systems. In
addition, short-range requirements are compatible with the limited performance
of today’s batteries, conversely to their current inapplicability for commercial
aviation purposes. For the present study, a parallel Hybrid Electric Propulsion
System for a coaxial-rotor Air Taxi has been implemented in Simulink and tested
on four different sets of operating conditions, with a transient signal as input for
the Power Lever Angle command. The goal of this investigation is to analyze the
transient behavior of the hybrid-electric propulsion system in question, to
underline the role of electric motors in assisting thermal engine during
transients, and, in particular, focuses on the benefits deriving from the adoption
of a coordination block which adapts torque split between the two power sources
on the basis of actual engine response.
