中文摘要： 当前，太阳能光伏发电普遍得到人们重视，并运用于多个领域，尤其是当今的研究热点- - 高空长航时飞行器上。但就目前研究而言，针对太阳能的光伏利用效率还相当低下（普遍在20%以下），这对尺寸和重量要求均十分苛刻的飞行器而言，无疑是设巨大的设计挑战。为此，本项目拟结合国内外已有研究成果，从组合式方案的基本构型和相应的物理模型入手，着重研究基于光伏发电和热电发电的组合式发电方案可能的构成形式、工作模式、输电特性、能源利用优势及其在飞行器上的应用可行性。以此为基础，开展先期的小尺寸样件研制与试验验证，并根据试验结果修正物理模型。进一步的，结合既定的飞行环境模型，针对某特定飞行器设计方案开展基于组合式发电单元的能源系统方案设计、组成部件建模和仿真模型集成，完成该飞行器在既定飞行条件下的能量动态变化特性分析并明确外部飞行条件对飞行器能量变化的影响规律，为相关复合能源飞行器的合理设计提供技术支持和方法借鉴。

英文摘要： Nowadays, solar energy photovoltaic power system has been generally recognized and used in many fields, especially in the present research focus-high altitude long-endurance aircraft. However, based on current research situation, the use efficiency of solar energy is still rather low(less than 20%), that is to say, it is a great challenge for the design of aircraft, which has rigorous requirements of size and weight. Therefore, we will combine with the existing study results at home and abroad, mainly studies the possible composition form of a combined power scheme, its working mode and the characteristics of the electrical transmission, its advantage of energy use efficiency and application feasibility of aircraft according to solar energy photovoltaic power system and solar photo-thermal power system by starting with basic configuration of the combined scheme and corresponding physical model. And then we will design and verify a small size test samples firstly, and modify the physical model by the experimental results. Furthermore, combined with the vested model of flight environment, the design of energy system, the modeling of composition parts and the integration of simulation models, which are all based on combined power unit and aiming at a certain specific aircraft design scheme, will be built. Based on
