Abstract

The invention discloses a micro gas turbine gas-electric hybrid power plant for an unmanned aerial vehicle. The micro gas turbine gas-electric hybrid power plant comprises an outer shell, a compressedair wheel rotatably arranged in the outer shell, an engine main shaft which is connected with the compressed air wheel in a transmission mode, is coaxial with the rotary center of the compressed airwheel, and is located in the outer shell, a permanent magnet arranged on the compressed air wheel, and a coil winding arranged in the outer shell corresponding to the permanent magnet, the coil winding is connected with a storage battery through a power output module, the end, close to the compressed air wheel, of the outer shell communicates with a gas turbine, and a sprayer nozzle for spraying air is arranged at the other end of the outer shell. The micro gas turbine gas-electric hybrid power plant for the unmanned aerial vehicle has the beneficial effects that fuel is used for supplying power, compared with a battery with the same mass, the fuel can provide more energy, thus the cruising ability of the unmanned aerial vehicle is improved, in the flying process, the fuel can be continuously consumed, the dead load of the unmanned aerial vehicle is gradually and advantageously decreased in the flying process, thus energy consumption is saved, the fuel is used for supplying the power,and the maximum take-off weight of the unmanned aerial vehicle can further be increased.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a micro gas turbine oil-electric hybrid power device for drones. Background technique [0002] At present, UAVs are more and more widely used in surveying and mapping, plant protection, power inspection, oil line inspection, border monitoring and other fields, but the shortcomings of short battery life and relatively small load capacity limit the professional UAV Human-machine development and promotion. Taking the traditional pure electric agricultural plant protection UAV as an example, it needs to be specially equipped with a truck with a large loading space to transport batteries and power generation equipment required for on-site charging during operation. cost. In response to this problem, there is currently a UAV power device that uses a combination of a micro piston engine and a micro generator. This device is installed on the UAV together with the fuel tank, and flies wi...
