Suspension-type helicopter

Abstract

The invention discloses a suspension-type helicopter which comprises a helicopter body. The helicopter body comprises a rack and at least two duct rotor wing components arranged on the rack. Each duct rotor wing component comprises a connecting shaft which is connected to the ends of the rack and can rotate around the horizontal axis, duct rotor wing motors which are arranged at the outer ends of the connecting shaft, rotor wings which are connected with the duct rotor wing motors and duct shells which are arranged outside the rotor wings. The rack is further provided with an operating hanging bin and a flying control module. The rack is further provided with at least two air sac fixing frames, and each air sac fixing frame is provided with an air sac. The air sacs inside the air sac fixing frames are fixed on the same horizontal plane by the air sac fixing frames. The air sacs are filled with gas, wherein the specific gravity of the gas is lower than that of the air. The suspension-type helicopter integrates the advantages of a common unmanned helicopter and the advantages of an airship and has the advantages of being large in load capacity, high in maneuverability and flexibility, high in security, simple in structure, strong in stability and the like when being used for farmland operations.

Description

technical field [0001] The invention relates to an aircraft, in particular to a suspended helicopter aircraft. Background technique [0002] Agricultural aircraft have high efficiency in aviation operations. For example, in wheat field weeding operations, the efficiency of aerial spraying is 5 to 7 times higher than that of ground machinery, which is equivalent to 200 to 250 times that of manual spraying. The effect of disease and insect pest control is good; it is not limited by the growth of crops, especially when the ridges are not clear after the crops grow to the closed row, aerial operations can solve the problem that it is difficult for ground machinery to work in the field in the late stage of crop growth. Compared with field operations, aircraft aviation operations also have the characteristics of lower operating costs, no rut marks and no damage to crops. [0003] At present, the aircraft used for agricultural aviation operations mainly include manned large fixed-...

AI Technical Summary

Problems solved by technology

[0005] However, unmanned miniature fixed-wing aircraft, single-rotor helicopters, and non-coaxial multi-rotor helicopters are still expensive and dangerous for ordinary agricultural workers, and high-speed rotors may hurt workers Or crops, improper operation is easy to "crash" or "explode the plane", which not only causes heavy losses to the plane itself, but also brings serious damage to the equipment on the plane and ground crops, and also brings safety threats to ground operators. Therefore, the safety of its use is one of the key issues restricting its rapid development.

In addition, the small payload of the aircraft and the short operating life are two other key issues restricting its rapid development

[0006] The price of airship is relatively moderate, the operation safety is relatively higher, and it is easy to maintain and has a large payload. However, the traditional airship structure has problems such as poor wind resistance, slow operation speed, and poor flexibility.

Especially in aerial photography and remote sensing operations, because aerial photography has high requirements on the stability of the airframe, the traditional airship structure generally adopts the traditional single airbag streamlined structure, the facade of the airship body is relatively high, and the mounted remote sensing information The relative center of gravity of the acquisition equipment is relatively low. This insufficiently compact structure greatly affects the stability of aerial work, especially in weather conditions with natural wind interference. Shaking is very obvious
