Description

Technical Field

[0001] This utility model relates to the field of aviation equipment technology, and in particular to a bracket for mounting satellite communication equipment on a helicopter. Background Technology

[0002] The Bell 412EP is a medium-sized twin-engine multi-purpose helicopter developed by Bell Helicopter Corporation, a modernized upgrade of the classic Bell 212 / UH-1 "Huey" series. The helicopter features a dual-engine design, allowing safe flight even in the event of a single engine failure, and offers long maintenance intervals, making it suitable for high-frequency operations. Its four-bladed composite main rotor provides high lift efficiency, making it suitable for high-altitude and high-temperature environments (such as mountains and deserts). The four-bladed rotor system also provides smoother hovering performance, ideal for precision operations (such as power line inspection and sling load operations). The flexible cabin can be quickly converted into configurations for medical evacuation (EMS), cargo transport, VIP transportation, etc., making it popular among small and medium-sized general aviation companies.

[0003] However, the existing Bell 412EP helicopter was not designed with a platform for installing satellite communication equipment. As a result, when adding satellite communication equipment, there is a lack of readily available fixed points on the fuselage, which requires additional drilling or modification, affecting the overall structural strength. Summary of the Invention

[0004] The purpose of this utility model is to provide a bracket for installing satellite communication equipment on a helicopter, which solves the problem that the existing Bell 412EP helicopter does not have a reserved installation platform for satellite communication equipment in its design, which leads to the need for additional holes or modifications when installing satellite communication equipment due to the lack of ready-made fixing points on the fuselage, thus affecting the overall structural strength.

[0005] To achieve the above objectives, this utility model provides a bracket for mounting satellite communication equipment on a helicopter. The bracket includes an airborne antenna assembly, a pod assembly, and a cabinet assembly. The airborne antenna assembly consists of an airborne antenna body and an antenna bracket. The airborne antenna is mounted on the top of the antenna bracket and located above the left cabin door of the cockpit. The pod assembly is mounted below the left front landing gear footrest of the helicopter. The cabinet assembly is mounted on the front seat connector next to the left passenger cabin door of the helicopter. The antenna support includes a mounting frame, a top cover, an antenna mounting plate, a flange support, a strut, and a bottom support. The mounting frame consists of a front crossbeam, a middle crossbeam, and a rear crossbeam arranged in parallel.
