说明

这是一种遥控式农业喷药小飞机，机体型娇小而功能强大，可负载10L农药，在低空喷洒农药，每分钟可完成一亩地的作业。其喷洒效率是传统人工的30倍。该飞机采用智能操控，操作手通过地面遥控器及GPS定位对其实施控制，其旋翼产生的向下气流有助于增加雾流对作物的穿透性，防治效果好，同时远距离操控施药大大提高了农药喷洒的安全性。

Description: This is a remote control agricultural spraying small aircraft, airframe type small and powerful, can load 10L pesticides, spraying pesticides at low altitude, every minute to complete the operation of one mu of land. Its spraying efficiency is 30 times that of traditional manual. The aircraft used intelligent control, manipulator through ground remote controller and GPS mapping of the implementation of control, the downdraft rotor helps to increase the flow of fog penetrating crops, good control effect, and remote control application greatly improves the safety of pesticide spraying


理念
在设计过程中，如何将无人机本身的重量降到最低是一大难题，同时还需要满足雨天作业，以及后期清洗的防水处理，由于内部元器件发热量大，散热也是一个令人头痛的问题。另一方面还需要降低无人机降落到地面时由于惯性对内部元器件的损害。 因此我们我们最后给出的方案为无人机外壳以及骨架均采用碳纤维材料，主体部分采用模块化设计，方便安装与拆卸同时解决防水问题。至于散热，我们设计了一款L型的吹塑水箱，在满足载药量不变的同时，让水箱辅助散热。然后在支架底部设计了缓冲器，有效解决了无人机降落时缓冲的问题。

In the design process, how will the UAV itself to a minimum weight is a big problem, but also need to meet the rain and water treatment operation, late cleaning, due to internal components of heat, heat is also a headache. On the other hand, there is also a need to reduce the damage to internal components due to inertia when the UAV lands on ground. Therefore, we finally give the program for the UAV shell and skeleton are carbon fiber material, the main part of the modular design, easy installation and disassembly, while solving the waterproof problem. As for heat dissipation, we designed a L type blow tank, which can be used to heat the tank at the same time as the loading dose is constant. Then the buffer is designed at the bottom of the support to effectively solve the problem of landing when the UAV is landing.



无人驾驶小型直升机具有作业高度低，飘移少，可空中悬停，无需专用起降机场，旋翼产生的向下气流有助于增加雾流对作物的穿透性，防治效果高，远距离遥控操作，喷洒作业人员避免了暴露于农药的危险，提高了喷洒作业安全性等诸多优点。另外，电动无人直升机喷洒技术采用喷雾喷洒方式至少可以节约50%的农药使用量，节约90%的用水量，这将很大程度的降低资源成本。

Small unmanned helicopter operation with low height, low drift, but hovering and without special landing airport, downdraughts rotor helps to increase the flow of fog penetrating crop, control effect, remote operation, spraying operation personnel to avoid the risk of exposure to pesticides, improve the advantages of spraying safety. In addition, the electric unmanned helicopter spraying technology adopts spray spraying method, at least 50% of the pesticide consumption can be saved, and 90% of the water consumption is saved, which will greatly reduce the resource cost.
