摘要：	A parametric study of the state of charge is performed using two separate battery models, i.e., energy-based and electrochemical-based battery models for a NASA-proposed conceptual multirotor aircraft in the urban environment. The parametric study is performed using an optimal control framework. The parameters considered for the parametric analysis are cruise airspeed, cruise altitude, climb profile, range, and required time of arrival under uncertainties (wind and departure-time). The key results suggest: i) the minimum-energy cruise airspeed (maximum final state of charge) increases with an increase in cruise altitude, ii) the minimum- energy cruise airspeed is independent of range; iii) design a cruise corridor for urban air mobility air traffic at the lowest possible altitude considering eddies/vortices from skyscrapers, other types of air traffic, and vertical obstacles, and iv) wind and departure-time uncertainties could adversely impact the predictability of the usage of the onboard lithium-ion polymer battery pack for an aircraft flying to meet the assigned required time of arrival in the urban air mobility environment. The state of charge results showed high dependence on the battery model. Therefore, this study demonstrates the need to have a validated battery model for the onboard lithium-ion polymer battery pack to predict the state of charge accurately.
