| 摘要: |
| 小型电动垂直起降飞行器的悬停续航性能取决于推进系统的性能。基于电池、电机、电调的质量模型和螺旋桨的推力-功耗关系，利用电池的恒流放电模型建立了垂直起降飞行器的续航时间评估模型，分析了推进系统参数和有效载荷对飞行器续航性能的影响规律，研究结论可用于电动垂直起降飞行器的总体设计和推进系统选型。 |

| Abstract: |
| The hover duration performances of miniature VTOL(Vertical Takeoff and Landing) air vehicles depend on the performance of propulsion system. Based on the mass models of battery, motor and ESC(Electronic Speed Controller), and the relationship between provided force and required power of propeller, the duration calculation model of vertical takeoff and landing air vehicles was established by using the battery constant-current discharge model. The influence of propulsion parameters and payload on vehicle duration is analyzed, which would be used for preliminary design of VTOL air vehicles and components selection of propulsion system. |
