Description

Technical Field

[0001] The utility model belongs to the technical field of aviation structures and relates to a novel antenna installation structure on the top of an aircraft carrying external attachments. Background Art

[0002] In order to meet the installation requirements of large equipment, special aircraft often use external attachments as installation structures, such as balance beam structures, dome structures, shield structures, etc. For example, a large external attachment platform is set on the back of a certain type of aircraft, and antenna equipment is installed on the top of the external attachment. Usually, in order to avoid the external attachment blocking the antenna on the back of the fuselage, the antenna in this area is arranged on the top of the external attachment. However, the height of the external attachment is relatively high from the ground, and the disassembly and maintenance of the antenna on the top are very difficult. The installation structure that takes into account the convenience of antenna disassembly and maintenance is the key difficulty in the design of the antenna installation structure on the top of the external attachment.

[0023] Combined with the attached drawings, a novel antenna installation structure for the top of an aircraft carrying external objects involved in the utility model is described in detail:

[0024] See attached Figure 1-5The utility model specifically designs an aircraft external attachment top radome mounting structure, wherein a large opening is arranged at the top of an external attachment 2 at the upper end of a fuselage 1, and a radome is installed at the large opening to form a closed space; a top antenna mounting platform 4 is arranged across the large opening, and a top antenna 6 is installed on the antenna mounting platform 4. A large opening 5 is arranged at the top of the external attachment 2, which can be used to arrange the top antenna on the one hand, and can also provide a passage for ground crew 7 to maintain the antenna inside the external attachment on the other hand. The antenna debugging and inspection work can be completed from the inside of the external attachment without removing the radome 3.

[0025] For the specific design structure, see the attached Figure 2 , 4 The antenna mounting platform 4 provides installation support for the top antenna 6. A maintenance opening 10 is provided on the antenna platform. The maintenance opening is located at the antenna cable connector and the motor installation location. Ground crew can quickly complete cable replacement and motor maintenance through the maintenance opening without disassembling the antenna.

[0026] In an implementation case of a specific design, the antenna mounting platform 4 of the mounting structure is installed with the external attachment skeleton 8 through a detachable connection, and a mounting bracket connecting hole 11 is designed on the mounting platform. When the top antenna 6 needs to be removed for maintenance, the mounting bracket 12 is fixed to the mounting platform 4 through the bracket connecting hole on the mounting platform, and the top antenna 6 is removed together with the mounting platform, and is placed at a suitable working height inside the external attachment through the mounting bracket. At this time, the antenna platform can also serve as an operating table for antenna maintenance, which is convenient for ground crew maintenance; when the maintenance work is completed, the antenna can be lifted to the antenna installation height together with the mounting platform through the mounting bracket and re-fixed and connected; in terms of design structure, in order to more flexibly adjust the height of the antenna mounting platform 4, a slide rail is provided on the external attachment skeleton 8, and the antenna mounting platform 4 is arranged on the slide rail. The height of the antenna mounting platform 4 can be quickly adjusted through the lifting mechanism on the mounting bracket 12.

[0027] The following design elements were mainly considered during the specific design of the present invention.

[0028] 1) When designing the antenna maintenance channel on the top of the aircraft carrying external loads, a large opening structure is set on the top of the external load to meet the space requirements for the maintenance of the top antenna inside the external load, and at the same time provide a channel for ground staff to inspect and debug the antenna and related equipment inside the external load, improving the inconvenience of traditional external maintenance solutions that require the use of large lifting equipment and the removal of the antenna cover before hoisting the antenna to the ground for maintenance;

[0029] 2) When designing the antenna installation platform structure, the daily maintenance needs of the antenna are taken into consideration. Maintenance openings are set on the antenna installation platform at the cable connector and motor installation location, so that ground staff can quickly complete cable replacement and motor maintenance through the maintenance openings without disassembling the antenna;

[0030] 3) The antenna installation platform is configured as a completely detachable structure, and a mounting bracket installation interface is provided on the antenna installation platform. When the antenna needs to be removed for maintenance, the antenna is removed together with the installation platform and placed at a suitable working height inside the external attachment through the installation bracket. At this time, the antenna platform can also serve as an operating table for antenna maintenance, which is convenient for ground crew members to maintain. When the maintenance work is completed, the antenna and the installation platform can be lifted to the antenna installation height through the installation bracket and re-fixed and connected.
