Embodiment Construction

[0060] In order to describe the content of the present invention in more detail, the specific embodiments will be introduced in detail with reference to the accompanying drawings.

[0061] The upper beam of a helicopter body of the present invention, such as figure 1 shown, figure 1 It is a schematic diagram of the upper frame structure of a helicopter body of the present invention. The upper beam 3 includes a U-shaped member composed of a bridging part 15 and two straight rod parts 14, and the two straight rod parts 14 are close to the bridging part 15. One end is bent or bent in the same direction at the same position to form the bent structure 16 . The upper beam 3 is made of bent aluminum pipes, and the bridging part 15 and the two straight rod parts 14 can be a one-piece structure, or can be a separate structure assembled together by socketing or other methods when the body is large.

[0062] The two straight rod parts 14 are bent or bent downward at the position close ...

Abstract

The invention discloses an upper beam, a helicopter airframe adopting the upper beam and a helicopter. The upper beam is a U-shaped component formed by two straight rod parts which are parallel to each other and a bridge joint part for connecting one ends of the two straight rod parts. The airframe is of a damping structure formed by mutual connection of an upper frame and a tripod through an engine assembly and a damper, the upper frame is of a rigid structure formed by the upper beam, a front beam, an upper bearing beam, supporting rods and a tail pipe through two pairs of middle beams with five connecting supporting arms, and three of the supporting rods are connected with three of the middle beams. A gearbox is positioned on the upper bearing beam. The airframe has the beneficial effects of being simple in structure, easy to manufacture, cost-saving, light in weight, good in rigidity, excellent in damping performance, easy for disassembling, assembling and maintenance, and the like.

Description

technical field [0001] The invention relates to an upper beam of an unmanned helicopter, an aircraft model helicopter or a manned helicopter, and also relates to a helicopter body and a helicopter using the upper beam. Background technique [0002] As the central support mechanism of the helicopter, the helicopter body is responsible for supporting and fixing components such as the engine, and has the function of fixing and connecting them together, and plays the role of bearing and force transmission. Therefore, the design of its entire body structure makes it sufficiently rigid for an unmanned helicopter. [0003] At present, most of the body structures of the unmanned helicopters, model helicopters or manned helicopters commonly used in the prior art adopt the side plate structure, and a few adopt the elbow structure and the skeleton structure. Among them, the side plate structure uses two side plates as the main frame of the fuselage to maintain its rigidity, so that th...
