Coaxial double-propeller and propulsion type tail rotor logistics transportation unmanned helicopter

Abstract

The invention discloses a coaxial double-propeller and propulsion type tail rotor logistics transportation unmanned helicopter. The unmanned aerial vehicle structurally comprises a vehicle body, an undercarriage, a logistics placement bin, wings and rotors, undercarriage is arranged on fuselage, two undercarriages are arranged, the symmetrical structure is mounted at the bottom of the body; the method has the beneficial effects that the method is simple; a balance weight cavity is formed in the bottom of the accommodating frame. The height and the angle of the unmanned helicopter are changed in the flying process. The weight difference between the left side and the right side of the spacing layer is filled by utilizing counterweight water in the counterweight cavity; implementing parallelism of spacer layers, the gravity center height of the spacing layer is always unchanged; in addition, the rubber layers are installed in the small interlayers on the spacer layers, so that the objectsare fixed, the friction force between the objects and the small interlayers is increased, the objects are not prone to displacement, and the integrity of the logistics objects and the safety of logistics transportation are guaranteed.

Description

technical field [0001] The invention relates to the field of intelligent modern logistics, in particular to an unmanned helicopter for logistics transportation with coaxial double propellers and a propelling tail rotor. Background technique [0002] The carrying capacity of passenger aircraft is limited. In order to facilitate the transportation of goods and save time, the transportation of goods by controlling unmanned helicopters makes the logistics transportation more convenient and time-sensitive. Therefore, the further development of unmanned helicopters in logistics transportation It is necessary to improve the research and development. The current unmanned helicopter with coaxial twin propellers and propelling tail propeller has the following defects: [0003] The existing coaxial twin propellers plus propelling tail rotor logistics transport unmanned helicopter pulls the lower main propeller through the server to change its tilt direction, so as to realize the left a...

AI Technical Summary

Problems solved by technology

[0003] The existing coaxial twin propellers plus propelling tail rotor logistics transport unmanned helicopter pulls the lower main propeller through the server to change its tilt direction, so as to realize the left and right lateral movement of the helicopter. During the flight, the flight height and angle When the change occurs, the overall height of the center of gravity of the goods in the warehouse will change accordingly, affecting the normal flight control of the unmanned helicopter and posing a safety hazard
