混合动力飞行汽车建模与性能仿真分析OA

As a crucial mode of transport in the future three-dimensional traffic,flying cars possess the capability of vertical takeoff and landing as well as power switching between cruise and hover modes.Range-extended hybrid electric flying cars combine the advantages of power batteries and gas turbines,providing a better solution for the energy demands of intercity transportation.Current research primarily focuses on aerodynamic characteristics analysis,traffic network planning,and propulsion system modeling of flying cars.However,there is a lack of quantitative studies on the optimal configuration of hybrid power systems for different flight mission parameters and the corresponding economic feasibility.This paper selects hybrid electric flying cars in the weight range of 1000～3000kg as the research subject.It analyzes and compares the mission economics and payload ratio for these flying cars under different power levels of gas turbine generator units during flight ranges of 60～360km.The results indicate that flying missions with a range exceeding 120km exhibit a minimal average cost,and the gas turbine power is near the cruise power at this point.Simultaneously,the payload ratio of flying cars is positively correlated with the gas turbine power level.For a 1000kg flying car,the mission average cost is positively correlated with the gas turbine power when the range is 60km.When the range exceeds 120km,the minimal average cost of the mission is approximately 0.004CNY/(km/kg).For flying cars in the 2000～3000kg weight range,the minimal average cost stabilizes around 0.004CNY/(km/kg)for ranges exceeding 120km.This paper quantitatively analyzes the impact of range and payload on the mission economics of both all-electric and hybrid electric flying cars,elucidating the suitable mission scenarios for each.The findings provide valuable insights for flying car and component manufacturers.
