Problems solved by technology

It must be returned to the factory for maintenance, and the vertical tail structure must be maintained at the same time, which is time-consuming and laborious
[0003] In particular, unlike the fixed-wing aircraft's horizontal tail, the helicopter's horizontal tail is relativ

Embodiment Construction

[0016] The present invention will be described in further detail below.

[0017] see figure 1 , the connecting device of the helicopter horizontal tail of the present invention has a fuselage connecting joint 1, one side of the fuselage connecting joint 1 is connected on the rear fuselage structure using a bolt combination 5, and the top of the other side is provided with double fork lugs for connecting with the horizontal tail , the double fork lug is connected with the mounting hole reserved on the main beam of the flat tail with the connecting bolt 2, the connecting nut 3, and the adjusting gasket 4. In this way, the plug and play of the flat tail can be realized, errors caused by complex assembly can be avoided, the installation and positioning are accurate, and the connection form is simple.

[0018] A triangular support structure is formed between the roots of the double-fork lugs of the fuselage connection joint to maximize the strength.

[0019] The triangular suppor...

Abstract

The invention belongs to the technology of a horizontal tail of a helicopter, in particular to a horizontal tail connection device for the helicopter. The horizontal tail connection device is provided with a fuselage connection joint, one side of the fuselage connection joint is combined and connected to a rear fuselage structure through a bolt, and double fork ears used for being connected with the horizontal tail are arranged at the top of the other side of the fuselage connection joint. The double fork ears are connected with mounting holes preformed in a girder of the horizontal tail through connecting bolts, connecting nuts and adjusting gaskets. The connection device capable of quickly dismounting and mounting the horizontal tail of the helicopter can dismount the horizontal tail only by manually dismounting the bolts without a large tool and is convenient to maintain the horizontal tail of the helicopter.

Description

technical field [0001] The invention belongs to the helicopter horizontal tail technology, in particular to a helicopter horizontal tail connecting device. Background technique [0002] The helicopter's horizontal tail is generally installed on the tail in a horizontal state. It is a horizontal stabilizer and plays a role in pitch stabilization. At present, most helicopters adopt the method of installing the flat tail on the tail boom, and reserve the hole position of the flat tail airfoil by the tail boom, and then fix the flat tail by installing a bolt on both sides. This installation method is very difficult to manufacture when reserving the hole position of the flat tail airfoil, and once installed, it is almost impossible to disassemble it, and it must be returned to the factory for repair, and the manufacturing and maintenance costs are high. Alternatively, the flat tail can be divided into two parts and riveted on both sides of the vertical tail respectively. In thi...
