The invention provides a large-load transportation unmanned aerial vehicle based on ducted fans. The large-load transportation unmanned aerial vehicle comprises a fuselage, a left wing, a right wing, a V-shaped empennage, main ducts arranged on the front portion and the rear portion of the fuselage and an auxiliary duct arranged at the fusion position of the left wing body and the right wing body. The fuselage is of a lifting body structure, the belly of the fuselage is flat, the back of the fuselage is in a plano-convex shape, the lower portion of the front end of a first main duct of the fuselage is designed to be an arc-shaped inwards-concave molded surface, and the rear end of the first main duct is tangent to the lower edge of the first main duct. The main ducted fan and the auxiliary ducted fan are horizontally arranged in the aircraft body duct, and the upper ends and the lower ends of the main ducted fan and the auxiliary ducted fan are provided with grids matched with the aerodynamic shape of the unmanned aerial vehicle. According to the unmanned aerial vehicle, the structural layout of a traditional fixed-wing unmanned aerial vehicle is improved, the lifting body fuselage is adopted for providing aerodynamic lifting force, and the requirements for vertical take-off and landing, rapid cruise and large load are met in combination with the ducted fans.

    本发明提供了一种基于涵道风扇的大载重运输无人机,包括机身、左右机翼、V型尾翼,布置于机身前后的主涵道,布置于左右翼身融合处的辅助涵道;所述机身采用升力体结构,所述机身腹部为扁平状、背部为平凸式外形,所述机身第一主涵道前端下部设计成弧形内凹型面,后端与第一主涵道下边相切;主涵道风扇、辅助涵道风扇均水平布置在机体涵道内,所述主涵道、辅助涵道上下两端设有与无人机气动外形匹配的格栅。该无人机对传统固定翼无人机结构布局进行改进,采用升力体机身提供气动升力,结合涵道风扇,满足垂直起降、快速巡航和大载重需求。
