1. can realize individual soldier's operation: through a large amount of configuration optimization and high integration, accomplish 700mm wheel base with unmanned aerial vehicle's size, be one of the lightest product among present long endurance, high accuracy aerial survey unmanned aerial vehicle. On this basis, no matter be during packing, transportation or actual operation, all can be accomplished by alone, convenience and flexibility when improving the use greatly.

2. The working efficiency is high: through the advanced designs of the low-resistance nose, the streamline battery cover 81, the whole light weight and the high-strength fuselage and the like, the unmanned aerial vehicle can keep 60 minutes of flight time in a 12m/s high-speed cruising state, the cruising mileage more breaks through 30 kilometers, and compared with the traditional aerial survey unmanned aerial vehicle, the operation efficiency is improved by 5 times.

3. The installation is swift: the unmanned aerial vehicle only needs two folding arms 35, only needs 30 seconds from the package to the start of the task, greatly improves the simplicity of initial preparation, and has obvious advantages under the conditions of task transition and the like.

4. High ease of use: through highly integrated ground station system, the user has been removed from and has prepared notebook computer, connect ground transceiver module, arrange numerous and complicated actions such as antenna, has realized taking promptly and has used, has promoted the ease for use greatly.

5. The method is stable and reliable: through the design of an X-shaped power arm, a large amount of structural reinforcement and electronic circuit integration, the unmanned aerial vehicle can realize all-weather high-strength operation, and can still keep flight safety in severe environments such as strong wind and the like.

6. After-sale maintenance is convenient: the unmanned aerial vehicle provided by the invention has the advantages that the base materials are easy to obtain, and through the modular design, once a problem occurs and the unmanned aerial vehicle needs to be replaced or maintained, only the module needs to be replaced, so that the after-sale cost is greatly reduced.

7. The expansion function is rich: through quick detach carry structural design, the distributed undercarriage 34 design in 4 limits, change carry that can convenient and fast, and fuselage lower part space is wide with the field of vision, can not produce undercarriage 34 and shelter from the scheduling problem, realizes "a tractor serves several purposes", greatly increased unmanned aerial vehicle's expansion function.

It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present patent.
