本文针对长航时无人机电推进系统的研制，开展了高效推进系统的研究。对于长航时无人机，由于其飞行功率和续航时间随推进系统效率的不同而变化很大，因此对其气动特性和推进系统的高效率提出了更高的要求。因此，在本研究中，由于发动机、螺旋桨的效率随使用条件的不同而变化很大，因此开发了跟踪程序来记录发动机、螺旋桨的性能，并利用现有试飞程序的记录来检查我们开发的程序的准确性。针对未来长航时太阳能无人机的发展，确定了电机的外加电压、螺旋桨的最佳转速和减速齿轮的传动比，以使推进系统在最佳飞行条件下获得最高的效率。
In the present study, we conducted the research on the high efficiency propulsion system for the development of long-endurance UAV with an electric propulsion system. For the long endurance UAV, fair aerodynamic characteristics with the high efficiency of the propulsion system is required because the flight power and the duration time of the long-endurance UAV vary greatly depending on the efficiency of the propulsion system. Therefore, in this study, the tracking program which records the performance of motor, propeller was developed because of their wide variation in the efficiency depending on the using condition, and records from the existing flight test program were utilized to check the accuracy of the program we had developed. For the development of future long-endurance solar UAV, we confirmed the applied voltage of motor, the optimal rotation of propeller and the gear ratio of reduction gear in order to get the highest efficiency on the propulsion system at the optimal flying condition.
