摘要:

激光输能无人机(UAV)由于飞行高度高和续航时间长等优势得到关注。从激光输能角度,基于无人机质量评估模型,建立了激光辐照功率密度和无人机输出功率以及飞行性能之间的函数关系。以Sky Sailor太阳能无人机为例,计算分析了激光输能无人机和太阳能无人机的升限和飞行包络。结果表明由于激光辐照功率密度大和光/电之间能量转化效率高,与太阳能无人机比较,可携带的有效载荷更大、升限更高、爬升和抗扰能力更强;随着激光辐照功率密度增大,即使电子设备和有效载荷的质量和功耗都增大,飞行包络很宽,同时,飞行速度增大,但实际升限有所降低。

Abstract:

The laser-motive unmanned aerial vehicle (UAV) has received wide attention due to its high flight altitude and long fight duration. The relationship between the laser radiation power density, the output power density of the UAV and flight performance is set up based on a mass evaluation model of the UAV. The ceiling and flight envelope between laser-motive and solar-motive UAVs are analyzed taking the Sky Sailor UAV as an example. The results show that a laser-motive UAV has the advantage of carrying more payload, having high ceiling and stronger ability to resist disturbance as compared with a solar-motive UAV. Besides, with the increase of laser radiation power density, the flight envelope is broader even though the mass and power consumption of the electronic devices and payload increase. Meanwhile, the flight velocity increases, but the actual ceiling decreases.

Key words: unmanned aerial vehicle, laser-motive, solar-motive, flight envelope, flight ceiling
