The invention provides an aircraft powered by an overhead contact system in real time. The aircraft does not need to carry a heavy and non-durable power battery. A pair of power-receiving poles is adopted insteadly, and in the flying process, the power grid can directly supply power to the aircraft through the power-receiving poles. The weight of an empty aircraft is greatly reduced, more importantly, the flight time of the aircraft is not limited by battery capacity, the aircraft can continuously fly as long as a power grid is not powered off, and the endurance time can even exceed that of a fuel-powered aircraft by dozens of times. The power grid directly supplies power, energy loss in the battery charging and discharging process is avoided, and electric energy is saved. The service range of the electric aircraft is greatly widened due to the prolonging of the endurance time, the economical efficiency and the environmental protection property of the aircraft are improved, and the overhead contact network power supply aircraft has wide application prospects in the fields of urban traffic, logistics and the like.
本发明提出一种利用架空接触网实时供电的飞行器,飞行器不需要再携带笨重而又不耐用的动力电池。取而代之的是一对受电杆,飞行过程中,通过受电杆,电网可以直接给飞行器供电。这不仅大大减轻了飞行器空机重量,更为重要的时其飞行时间不再受制于电池容量的飞行,只要电网不断电,飞行器就可以持续飞行,续航时间甚至可以超过燃油动力飞行器数十倍。电网直接供电还省去了电池充放电过程中的能量损失,节约电能。续航时间的变长将大大拓宽电动飞行器的使用范围,并且提高了飞行器的经济性、环保性,在城市交通、物流等领域具有广泛的应用前景。
