Abstract

The rapid connecting structure comprises a horizontal empennage butt joint beam, a vertical empennage box-shaped reinforcing piece, a stop flange and a stop piece, the horizontal empennage butt joint beam is a composite material round pipe, penetrates through a horizontal empennage rib web plate and is fixed to the rib web plate through the stop flange, the front end of the horizontal empennage butt joint beam is exposed out of a horizontal empennage, and the stop piece is fixed to the horizontal empennage box-shaped reinforcing piece. The front end of the horizontal empennage butt-joint beam is inserted into a butt-joint hole preset in the vertical empennage box-shaped reinforcing piece, the vertical empennage box-shaped reinforcing piece is of a composite laminated plate structure with a C-shaped section and is located at the end of a vertical empennage, and a stop hole is formed in the front end of the horizontal empennage butt-joint beam. In addition, the front end of the horizontal tail butt-joint beam is limited in an abdominal cavity on one side of the vertical tail box-shaped reinforcing piece through a retainer.

Description

technical field [0001] This application relates to the design of unmanned aerial vehicles, and is a connection structure and connection method for realizing the rapid assembly and disassembly of the horizontal tail on the vertical tail on the unmanned aerial vehicle. Background technique [0002] At present, the connection form of the horizontal tail and the vertical tail of the high-level tail unmanned aircraft is usually: a single ear joint is arranged on the horizontal tail beam, and a double ear joint is arranged on the vertical tail. In order to ensure the reliability of the connection, the connection between the joint and the beam Bolt connection is used. During assembly, in order to ensure the disassembly of the horizontal tail, the single ear joint of the horizontal tail and the double ear joint of the vertical tail are connected by bolts. However, this connection method has a large number of parts, heavy weight, complex assembly process, low assembly efficiency, lon...
