摘　　要：文章统计了现有典型太阳能飞机总体参数值,提炼出了太阳能飞机的低翼载荷特性,然后以翼载荷为主要对象,以太阳能飞机飞行原理为引导,对总体设计中的关键参量进行了敏度分析,总结出了太阳能飞机总体设计的关键技术攻关点。在此基础上,提出了适用于太阳能飞机的以能量为中心的总体综合设计方法,以瑞士太阳能飞机"HB-SIA"作为实例对该方法进行了验证,该方法在太阳能飞机总体方案设计阶段十分有效。Using statistics collected on four successfully-flown solar-powered airplanes,whose wing loadings are comparatively low,sections 1 and 2 of the full paper try to sum up the most basic flight principles of a solar-powered airplane and then perform the sensitivity analysis of its key parameters at the conceptual design phase.With the help of Fig.7,section 3 explains our energy-centered conceptual design method suitable only for the solar-powered airplane.The successfully-flown Swiss solar-powered airplane ＂HB-SIA＂ is one of the four successfully-flown solar-powered airplanes.When section 3 applies our energy-centered conceptual design method to it,naturally no contradiction occurs.
