研制了翼展4.8m的太阳能无人机,光照强度较大时由太阳能电池直接为动力系统供电,光照不足时由锂电池进行供电。通过Profili软件对机翼分析后,采用具有大展弦比的机翼GOE500;太阳能电源由72片太阳能电池组成,最大功率可达288W;在翼肋上表面利用超透薄蒙皮对太阳能电池片进行保护,并封装在翼肋中。测试表明,由于飞行姿态和负载的变化,太阳能电池的输出功率具有波动性;平飞巡航功率只需80W;当太阳能电池输出功率在130W以上时,太阳能无人机可成功进行高度爬升。
Developed a solar energy unmanned aerial vehicle with a wingspan of 4.8m. When the light intensity is large, the solar battery supplies power directly to the power system. When the sunlight is insufficient, the lithium battery supplies power. Profili software to the wing after the analysis, the use of a large aspect ratio wing GOE500; solar power from 72 solar cells, the maximum power up to 288W; the surface of the ribs using ultra-thin skin on the solar cells Protected, and encapsulated in the ribs. The test shows that due to the change of flight attitude and load, the output power of the solar cell is fluctuating; the flat fly cruise power is only 80W; and when the output power of the solar cell is more than 130W, the solar drone can successfully climb highly.
