Tail wing connection structure suitable for small-sized unmanned plane with tailboom

Abstract

The invention discloses a tail wing connecting structure suitable for a small-sized unmanned plane with a tail support. An even tail and the tail support, and a vertical tail and the tail support of the small-sized unmanned plane are connected by positioning pins and sealed by sealing compounds, so that the even tail, the vertical tail and the tail support form an integral structure; one end of each positioning pin is inserted into a horizontal tail wing or a vertical tail wing, and adhered by the sealing compounds; and after the positioning pin and the tail wing are connected integrally, theother end of the positioning pin is inserted into the tail support to function as positioning. The connecting mode is quite convenient to assemble and disassemble the plane; and the connecting structure not only simplifies technical structure, lowers cost and improves production efficiency, but also effectively reduces weight of the plane and improves safety and reliability of the plane.

Description

technical field [0001] The invention relates to the field of aviation manufacturing, in particular to an empennage connection structure applied to a small unmanned aerial vehicle with a tail support. Background technique [0002] UAVs with tail supports (usually double tail supports) are a large category of UAVs. The advantages are that the tail support structure is light in weight, small in size and simple in structure compared with the fuselage structure. The double tail support structure can Free up the space at the rear of the fuselage to install the engine. In order to ensure that there is enough space for the propeller to rotate, most of the UAVs that use push-back piston engines currently adopt a double-tail support structure design. [0003] The tail of the double tail support UAV is usually composed of two tail supports, two vertical tail fins and a horizontal tail fin; for the convenience of decomposing and packing, these five parts are usually made into detachabl...

AI Technical Summary

Problems solved by technology

[0004] 1. In terms of aerodynamics, processing technology and beautiful appearance, the tail braces are usually designed as cylinders or cones, while the end faces of the flat tail and the vertical tail are usually flat, and there is a surface connection transition between the flat and the arc surface. question

[0005] 2. There are at least four "live connections" between the five components mentioned above, and the structural design and electrical interface design of these connections will increase the weight and production cost of the entire tail

[0006] 3. The increase in active connections will increase the complexity, which will reduce the safety and reliability of the aircraft

[0007] 4. There are too many detachable parts, which greatly reduces the rapid deployment and recovery capabilities of the aircraft
