Problems solved by technology
[0003] At present, domestic ultra-light helicopters are still in the initial stage of development, because of the structural design problems of the fuselage, resulting in bottlenecks such as high cost, insufficient stability, and low matching between the fuselage and load equipment, which have always restricted the development of ultra-light helicopters. widely used
The frames of traditional ultra-light helicopters are mostly plate structures. The plate structure has the following problems. The frame of the plate structure is heavy in weight, and the structure of the plate structure is relatively complicated and takes up a large space, which cannot meet the needs of ultra-light helicopters. Liter aircraft in terms of weight and space requirements
[0004] Patent CN201310454463.0 discloses a new type of electric unmanned helicopter with tubular structure. Its structure adopts a four-tube fuselage structure (1), that is, the main frame is composed of four circular pipes, and the fixed buckle is used to connect with the unmanned helicopter. The transmission part of the helicopter, the tail part, the gimbal and the tripod are connected. Although the patent CN201310454463.0 discloses a tubular helicopter, there is no tubular manned helicopter in the field of manned ultralight helicopters. Coverage of the rack of the helicopter

The invention provides a tubular ultra-light helicopter frame, and relates to the technical field of ultra-light helicopter frames. The purpose of the invention is to provide a tubular plane frame with the advantages of light weight, high stability and space saving. The frame comprises a bottom support (1-5, 1-6 and 1-2), a middle support (2-1, 2-2, 2-3 and 2-4) and a top support (3-1, 3-2, 3-3 and 3-4) which are arranged from bottom to top and are composed of tubes; the bottom support (1-5, 1-6 and 1-2) is provided with lower supporting beams (4) made of tubes and connected with the middle support (2-1, 2-2, 2-3 and 2-4); the middle support (2-1, 2-2, 2-3 and 2-4) is provided with middle supporting beams (5-1, 5-2-1, 5-2-2 and 5-3) made of tubes and connected with the top support (3-1, 3-2, 3-3 and 3-4); and the top support (3-1, 3-2, 3-3 and 3-4) is provided with top supporting beams (6-1, 6-2 and 6-3) made of tubes and used for supporting a gravity supporting plate (7).
Description
technical field [0001] The invention relates to the field of ultralight helicopters, and provides a tube-type ultralight helicopter frame. Background technique [0002] With the research on the application of ultra-light helicopters in various industries, people have found that unmanned helicopters play an increasingly significant role in all aspects of social production and life. The use of modern high-tech machinery and equipment can not only improve work efficiency and quality, but also reduce operating costs. [0003] At present, domestic ultra-light helicopters are still in the initial stage of development, because of the structural design problems of the fuselage, resulting in bottlenecks such as high cost, insufficient stability, and low matching between the fuselage and load equipment, which have always restricted the development of ultra-light helicopters. widely used. The frame of traditional ultra-light helicopters is mostly plate structure, and the plate stru...
