A shell-bearing unmanned helicopter fuselage structure

Abstract

The invention discloses a fuselage structure of an unmanned helicopter with a bearing shell. A fuselage is divided into a fuselage main body structure (2), an upper opening cover A (1), an upper opening cover B (3), a tail beam (5), a lower opening cover A (6), a lower opening cover B (8), a landing gear (7), a horizontal plate (9), a reinforcing framework A (10), a reinforcing framework B (11) and a vertical tail wing (4), wherein the landing gear (7) is fixedly connected with the fuselage main body structure (2); the vertical tail wing (4) is fixedly connected with the tail beam (5) and the fuselage main body structure (2); the upper opening cover and the lower opening cover are detachably connected with the fuselage main body structure (2); the upper opening cover A (1) is an engine chamber; the upper opening cover B (3) is an electronic device chamber; the lower opening cover A (6) and the lower opening cover B (8) are load chambers. By virtue of the fuselage structure of the unmanned helicopter with the bearing shell, the problems of the conventional unmanned helicopter that the structural mass is large, the skin easily loses stability and the joint of the skin is not sealed tightly of the fuselage structure can be solved.

Description

technical field [0001] The invention relates to an unmanned helicopter fuselage structure bearing a shell force, relates to the component design of a small unmanned helicopter, and belongs to the technical field of aviation vehicle design. Background technique [0002] Unmanned helicopters are generally used for military tasks such as aerial targets, battlefield reconnaissance, damage assessment, and target guidance. They can also be used for non-military tasks such as flight tests and aerial surveying and mapping. Compared with fixed-wing aircraft, unmanned helicopters have functions such as hovering and vertical take-off and landing, and can perform tasks more flexibly. Due to the many parts of the unmanned helicopter, the position of each part needs to comprehensively consider the center of gravity of the whole machine, use requirements, installation interference and so on. And because the unmanned helicopter has a limited load, the overall structure design of the whole ...
