The wind-sand-resistant ducted unmanned aerial vehicle comprises a main body bracket, a ducted shell, a propeller mechanism, an undercarriage mechanism and a load control module, the main body support is in a cross shape, the duct shell is located outside the main body support, four propeller mechanism installation grooves are formed by the duct shell and the main body support, and one propeller mechanism is installed in each groove. A set of undercarriage mechanism is arranged below each set of propeller mechanism; and the load control module is arranged below the main body bracket. The wind-sand-preventing unmanned aerial vehicle is especially designed for coping with severe working conditions such as wind-sand weather, a first wind-sand-preventing barrier is formed through the streamline duct shell, gravel carried by strong wind is prevented from impacting internal components of the unmanned aerial vehicle, ordered wind currents are formed in the duct shell, larger lift force can be obtained when the power of the propellers is not changed, and flight is more stable; the blades are reinforced by the composite material to form a second sand-proof barrier, so that the fracture resistance of the blades is improved, and the air crash risk of the unmanned aerial vehicle is reduced; by adding a buffer design to the undercarriage, the landing safety of the unmanned aerial vehicle on the gravel ground is improved.
一种抗风沙涵道无人机,包括主体支架、涵道外壳、螺旋桨机构、起落架机构及负载控制模块;主体支架为十字形,涵道外壳位于主体支架外部,二者形成四处螺旋桨机构安装槽,每一处槽内均安装有一套螺旋桨机构;每一套螺旋桨机构下方均设有一套起落架机构;负载控制模块设于主体支架下方。本发明特别为应对风沙天气等恶劣工况而设计,通过流线型涵道外壳形成第一道防风沙屏障,避免大风裹挟的砂石撞击无人机内部构件,涵道外壳内部形成有序风流,在螺旋桨功率不变时可获取更大升力,飞行更加平稳;通过复合材料强化桨叶形成第二道防风沙屏障,提高桨叶抗断裂能力,降低无人机坠机风险;通过对起落架增加缓冲设计,提高无人机在砂石地面的降落安全性。
