Description

technical field [0001] The invention relates to the field of energy technology, in particular to a laser energy transmission power supply system. Background technique [0002] High-altitude and long-endurance unmanned aerial vehicles are one of the development directions of future unmanned aerial vehicles. At present, the most promising high-altitude and long-endurance unmanned aerial vehicles include solar-powered unmanned aerial vehicles and stratospheric airships. , the efficiency of thin-film solar cells is low, and the specific energy of energy storage cells is not high, and it is difficult to improve greatly in a short period of time, resulting in great difficulties in the energy balance design of high-altitude and long-endurance unmanned aerial vehicles. In addition, even if the energy balance is met, it is difficult to supply power to the load or have a surplus power, which seriously limits the endurance time of the unmanned aerial vehicle during high-altitude and lo...
