Aerial vehicle structure

Abstract

An air vehicle structure comprises a framework structure and a skin connected with the framework structure, wherein at least one of the framework structure and the skin is made of plate metal; the plate metal comprises a first panel, a second panel as well as a plurality of hollow tubes arranged between the first panel and the second panel, and brazing layers are arranged between the hollow tubesand the first panel as well as between the hollow tubes and the second panel; a turning edge is arranged at at least one end of the hollow tubes. The aerial vehicle structure has the advantages of being small in self-weight, high in strength, stable in structure, high in impact resistance, capable of insulating sound and reducing noise, resistant to high temperature, corrosion and vibration, longin service life, capable of being carried and spliced and the like.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an air vehicle structure. Background technique [0002] .Most of the existing air vehicle shells are made of titanium alloy, aluminum-lithium alloy and other materials through stamping and forming to form various structures of the vehicle. The aircraft made of these materials mainly have the following defects: First, most of them are solid The structure is heavy; second, once damaged, it is not easy to repair; third, the performance of vibration isolation and noise reduction is poor; fourth, the insulation effect is poor. [0003] At present, there are also shell structures made of honeycomb panels. The honeycomb panels include upper and lower panels and honeycomb cores, thereby improving lightweight. However, the honeycomb core is connected into one body through multiple honeycomb structures, and the upper and lower ends of the honeycomb core are in line contact with the upper and lower...

[0002] .Most of the existing air vehicle shells are made of titanium alloy, aluminum-lithium alloy and other materials through stamping and forming to form various structures of the vehicle. The aircraft made of these materials mainly have the following defects: First, most of them are solid The structure is heavy; second, once damaged, it is not easy to repair; third, the performance of vibration isolation and noise reduction is poor; fourth, the thermal insulation effect is poor

However, the honeycomb core is connected into one body through multiple honeycomb structures, and the upper and lower ends of the honeycomb core are in line contact with the upper and lower panels. During the welding process, the welding process between the honeycomb core and the upper and lower panels will be weak, and gaps or voids will easily occur. , resulting in unstable overall structure, low strength, poor impact resistance, etc.

In addition, the honeycomb core can only be connected into one body. As long as one part of the connection is not firm, it will easily affect other parts over time, thereby reducing the stability of the overall structure, thereby reducing the strength and service life.
