Problems solved by technology

At present, the development of aviation high-performance power battery technology is mainly limited by the bottleneck of power battery volume-to-weight ratio and instantaneous charging technology development, as well as the contradiction between heavy load of electric aircraft and rapid loss of power motor power. The defects of this electric system make The performance of electric aircraft is usually characterized by insuffic

Example Embodiment

[0021] Further detailed description of the technical solutions of the present invention will be described below with reference to the drawings:

[0022] like figure 1 As shown, the method of working in the present invention is: an overhead contact network power supply aircraft system includes a front airfoil 1, a fuselage 2, a motor 4, a rear wing 5, a collector rod 6, a brush 7, and a power line 8 And the pole 9. The front airfoil 1 and the rear wing 5 are connected to the fuselage, located on the front and rear portions of the body 2, which acts in the front flight, and unloads the convergence of the context; the context is four, Located on both ends of the front air wing and the back wing, the two contexts are connected to the front airfoil 1, and the two connotations behind the rear are connected to the back wing 5, and their effect is to generate lift and overcome the resistance of flight; There are four in the motor 4, which are located in the center of four contexts. It is ...

Abstract

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.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an aircraft powered by an overhead catenary. Background technique [0002] Due to the dependence of traditional general-purpose aircraft on fossil energy, it has brought about a large amount of greenhouse gas emissions. In recent years, electric aircraft with the advantages of environmental protection, low pollution, low noise, and low vibration have received extensive attention. At present, the biggest obstacle to the development of all-electric aircraft is the low energy density and power density of the electric energy storage system, which cannot compare with traditional aircraft in terms of endurance time and load. At present, the energy consumption ratio of the power battery is much higher than the average fuel consumption rate of the fuel engine after being converted into the equivalent fuel consumption rate. Under the condition that the relevant parameters are equivalent to those ...
