Problems solved by technology

The traditional single-rotor UAV, due to the long rotor length, occupies a large area when rotating at high speed, and poses a greater security threat to ground personnel and objects during take-off and landing. However, multi-axis UAVs currently only use Limited battery power leads to short flight time and small load, which cannot meet the requirements of flight time and load at the same time, and has poor safety. Neither of these two types of drones can meet the requirements of air logistics carriers in cities, remote areas, and mountainous areas.

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with accompanying drawing, please refer to Figure 1 to Figure 6 .

[0028] like figure 1 and figure 2 As shown, a logistics unmanned helicopter includes a fuselage 1 and a rotor arranged on the fuselage 1. The fuselage 1 is a cross-shaped structure, and four fuselage frames 2 are fixed on the cross-shaped structure to support the fuselage 1. Starting from the central position of the fuselage 1, a central coaxial counter-rotating dual-rotor 3 is installed, powered by an oil-powered engine 4, and four electric quadrotors 5 that provide attitude adjustment capabilities are installed at the four ends of the cross-shaped structure. The four electric quadrotors 5 are respectively powered by four brushless motors 6 , and the cargo frame 7 with a rectified shape is suspended under the fuselage through the cargo frame 8 . like Figure 4a to Figure 4c As shown, the logistics cargo frame is a cent...

Abstract

The invention belongs to the technical field of aviation, relates to an unmanned aerial vehicle, and in particular relates to an unmanned logistics helicopter. The unmanned logistics helicopter comprises a body and rotor wings arranged on the body, wherein the body is of a cross-shaped structure; four body frames are fixed on the cross-shaped structure to support the body; central coaxial opposite-rotating double rotors are mounted at the central position of the body and are powered by an oil drive engine; four electric quad-rotor-wing supplying posture adjusting capacities are mounted at four tail ends of the cross-shaped structure and are powered by four brushless motors respectively; a cargo frame with a rectification shape is hung below the body through a cargo frame bracket. The unmanned logistics helicopter has the advantages of high endurance, safety, energy utilization and convenience in ground control, and can be put into use as an unmanned logistics aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of aviation, and relates to an unmanned aerial vehicle, in particular to an unmanned logistics helicopter. Background technique [0002] As the pace of urban life continues to accelerate and the requirements for logistics efficiency continue to increase, traditional ground vehicle transportation can no longer meet the needs of fast and real-time express delivery, and UAV air logistics has emerged as the times require. In remote areas and mountainous terrain, especially in scenic spots such as Mount Tai, the mountain roads are rugged, and human transportation of goods is time-consuming, laborious, and inefficient. Relying on logistics drones will greatly improve the efficiency of goods distribution and reduce labor costs. The traditional single-rotor UAV, due to the long rotor length, occupies a large area when rotating at high speed, and poses a greater security threat to ground personnel and objects during ...
