Duct airship helicopter

Abstract

The invention discloses a duct airship helicopter which comprises a helicopter body and a working nacelle, wherein the helicopter body comprises a stander and a plurality of rotor wing arms which are positioned along the radial direction outwards by taking the stander as a center; a rotor wing and a rotor wing motor are arranged at the tail end of each rotor wing arm; the rotor wings are upward; an upper air bag and a lower air bag are arranged above and below the helicopter body respectively; the upper air bag comprises air bag bodies equal to the rotor wings; a circular hole for accommodating the corresponding rotor wing is formed in the center of each air bag body; the middle of the upper air bag is provided with an upper connection seat connected with the stander; the center of the upper part of the lower air bag is provided with a lower connection seat connected with the helicopter body; the lower air bag expands around by taking the lower connection seat as a center; and gas with the specific gravity lower than that of air is filled in the upper air bag and the lower air bag. The duct airship helicopter integrates the advantages of a conventional unmanned helicopter and a conventional airship and has the advantages of high load, high maneuverability, high safety and the like when working in a farmland.

Description

technical field [0001] The invention relates to an aircraft, in particular to a ducted airship helicopter. 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-wing...

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.
