Embodiment approach

[0015] The multi-purpose plug-in device is mainly composed of the following two parts:

[0016] The main bearing box section 1 is composed of front beam 2, rear beam 3, 1# rib assembly 4, 2# rib assembly 5, 3# rib assembly 6, 4# rib assembly 7, 5# rib assembly 8, 6# rib assembly 9, 7# Rib 10, upper skin assembly 11, lower skin assembly 12, fuselage connection joint 13, and sealing rubber pad 16 form an integral structure through riveted connections, and the front beam 2 and rear beam 3 adopt an angled layout , the angle is 16 degrees, the front beam 2 and the rear beam 3 are integral machined beam structures, the upper and lower surfaces of the front beam 2 and the rear beam 3 are fitted with the upper skin assembly 11 and the lower skin assembly 12, and the front beam 2 Two columnar nuts 17 are arranged in the middle of the front beam 2, two columnar nuts 18 are arranged at the end of the front beam 2, two columnar nuts 19 are arranged at the middle of the rear beam 3, and tw...

Embodiment 1

[0019] The multi-purpose hanging device of the present invention is mainly composed of two parts, the main load-bearing box section and the detachable front and rear edge fairings. The main load-bearing box section is mainly composed of the front beam, the rear beam and the inter-beam rib assembly, as well as the upper and lower skin assemblies through riveted connections, and the detachable fairings at the front and rear edges are connected to the main body of the box section through screw connections. , and finally the external device is connected to the helicopter body through a butt joint located on the outer surface of the upper and lower skins by screwing.

Abstract

The invention belongs to the technical field of structural designs of helicopters, and relates to a multi-purpose plug-in device for a helicopter. The multi-purpose plug-in device for the helicopter provided by the invention is fixed at the left side and right side of the helicopter through bolts, so that simplicity and convenience in dismounting and strong interchange property can be realized; two mount points are arranged at the single side, so that the mount capacity of the helicopter is greatly improved; the multi-purpose plug-in device has a specific structural manner, so that not only can good rigidity be realized, but also the entire aerodynamic performances of the helicopter can be improved, the structural weight of a helicopter body is reduced, and the advantages of convenience in dismounting, benefits on interchange and maintenance and the like can be realized. The multi-purpose plug-in device for the helicopter provided by the invention uses an interchange design manner, is in a double-beam type structure manner, and forms a sealed box section with upper and lower skin assemblies and a beam rib assembly, so that the entire structure has the advantages of direct transmission, light weight, large rigidity and the like; the mount capacity is improved, and four hooks can be mounted on the left side and the right side; the multi-purpose plug-in device for the helicopter uses the interchange design and is beneficial to maintain; and the aerodynamic performance of the helicopter can be improved.

Description

technical field [0001] The invention belongs to the technical field of helicopter structure design, and relates to a multipurpose external device for helicopters. Background technique [0002] The current design of the mounting and hanging platform on the helicopter is mainly based on the curved beam structure. Although it can meet the requirements of use, the helicopter mounting and hanging platform has the disadvantages of heavy weight and weak loading capacity. Contents of the invention [0003] The purpose of the present invention is to propose a multi-purpose external device for a helicopter that strengthens the loading capacity of the helicopter, improves the aerodynamic performance of the helicopter and reduces the weight of the overall mechanism of the helicopter. [0004] The technical solution of the present invention is that the external hanging device includes a main load-bearing box section, a front edge fairing and a rear edge fairing, and the main load-beari...
