Abstract

The invention provides a fuselage butt joint structure connected with an aircraft vertical fin. The fuselage butt joint structure comprises a structure main body and a plurality of joints, wherein the structure main body is provided with a plurality of reinforcing ribs; the plurality of joints are installed on the front side and the rear side of the structure main body back to back in pairs; two ends of each joint are respectively provided with the reinforcing ribs; the reinforcing ribs of the joints are connected to the reinforcing ribs of the structure main body through fastening elements; the aircraft vertical fin is installed on the joints through fastening elements. The fuselage butt joint structure provided by the invention has favorable fatigue property, maintenance property, technology property and economical property.

Description

technical field [0001] The invention relates to the field of fuselage structure design, in particular to a fuselage docking structure connected to an aircraft vertical tail and an aircraft comprising the fuselage docking structure. Background technique [0002] In the design of aircraft structure, we should strive to achieve the overall integrity of the structure. However, due to the needs and limitations of structural design, technology, use and maintenance, etc., a design and technology separation surface must be arranged between the fuselage and the vertical tail. The connection design of these parts is very important. become an essential key link. [0003] The connection area of ​​the aircraft is a part of the structure that is prone to damage. Therefore, a well-designed fuselage and vertical tail docking structure will improve the load-carrying efficiency. Structural design also needs to consider maintainability, manufacturability and economy. [0004] The traditional...
