| 摘要: |
| 文章根据太阳能无人机推进系统的特点,建立了电机螺旋桨的数学模型。通过分析系统产生的推力随飞行状态的变化关系,以及推进系统在大展弦比飞翼式太阳能无人机上的分布,采用线性化方法,计算了分布式的推进系统对高空长航时太阳能无人机飞行品质的影响。研究了分布式推进系统分布位置、控制方式等与无人机飞行品质之间的关系。从飞行品质要求和推进系统的整体效率出发,对各推进系统的参数进行了选取,最后通过非线性模型对分析结果进行了仿真验证。 |

| Abstract: |
| Sections 1 through 3 of the full paper explain the determination of the effects mentioned in the title and then propose an optimization scheme based on such determined effects; we believe that both our determination andoptimization scheme mentioned above are effective. The core of Sections 1 through 3 consists of: (1) we establishthe mathematical model for the motor-propeller propulsion system of HALE solar UAV; (2) we analyze the relation-ship between flight conditions and output thrust of the distributed propulsion system; (3) we linearize the model,and, based on the study of flight quality of large aspect-ratio solar UAV, deduce the effects of distributed propulsionsystem on lateral flight quality of the solar UAV,which are altered by the distribution and control scheme of propul-sion system; (4) for the purpose of long flight endurance,we propose an optimization scheme; (5) simulation re-sults,presented in Figs. 5 through 7,and their analysis show preliminarily that our optimization scheme is indeedeffective. |
