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
