中文摘要：

针对太阳能无人机能量生产问题,研究并提出一种综合无人机运动学的能量生产估计模型。首先,对世界范围内近20年来所采用的太阳辐射模型进行简要分析,并对其特点进行总结;其次,通过分析太阳能无人机应用环境,结合太阳能辐射模型特点,并基于精度可用、计算简便的工程应用原则,确定ASHRAE晴空模型作为能量生产的太阳辐射估计模型;最后,通过推导无人机姿态角和太阳角之间相互关系,求解出太阳光入射到翼面太阳能电池的入射角,从而借鉴斜面太阳能辐射强度计算方法,结合太阳能电池转化效率,最终得出与太阳能无人机姿态运动相关的太阳辐射能量生产估计模型。仿真实验表明该模型可用于估计太阳能无人机执行飞行任务时的能量特征且简单易用。

英文摘要：

An integrated energy model of solar-powered aircraft with level flight is presented in order to estimate solar energy collected by the aircraft at anytime and anywhere of the world. Firstly,a brief introduction of clear sky models for insolation is described,and its characteristics are summarized. Then,by analyzing its characteristics and the application environment of solar aircraft,a simplified clear sky model is chosen. Next,according to the solar angles upon the local solar time and attitude angles of the airplane,the angle of incidence of the sunray on the aircraft’s surfaces is derivate. Finally,series numerical simulations are present,it demonstrates that the model is simple and practical to analyzing the feasibility of perpetual endurance capabilities for the solar-powered aircraft.
