特种太阳能飞机总体参数设计方法研究

摘要

The solar-powered aircraft is suitable for reconnaissance, warning or weapons aerial platform, because it has many advantages like longer cruise time, higher flight altitude, less power constrains, etc. The flight principles of solar-powered aircraft and balance of energy are expound. Combined with mission payload model and give out a conceptual parameter design method of special solar-powered aircraft are presented. At last, take surveillance aircraft for example, reasonable radar antenna is choiced, the solar-powered aircraft shape parameters is designed, the aerodynamic and electromagnetism performance of that is analysed, the feasibility of method is confirmed. The basis for the design of the special solar-powered aircraft is provided.%由于高空长航时太阳能飞机具有巡航时间较长、飞行高度较高、不受能源限制等优点,适合作为侦察、预警或武器的空中平台.首先阐述了太阳能飞机飞行原理及能量平衡关系.结合任务载荷建模.提出一种特种太阳能飞机初步方案的设计方法.最后以太阳能侦察机这种特种太阳能飞机为例,合理选择雷达天线,设计出太阳能飞机各外形参数.分析了其气动及电磁性能.验证了设计方法的可行性.为特种太阳能飞机的设计提供依据.
