Description

Technical Field

[0001] This invention relates to an installation structure for mounting a domestically produced satellite phone on an aircraft, and also to an installation method using the installation structure. Background Technology

[0002] As civil aviation safety requirements continue to rise, installing satellite phones on commercial airliners provides crew members with an important emergency ground communication method. Currently, the technology for installing satellite phones on aircraft is controlled by foreign manufacturers, and using foreign phones carries uncontrollable risks such as leaked conversation content and remote shutdown of the phones. Therefore, retrofitting the cockpit with domestically produced satellite phones has significant safety implications.

[0003] Currently, satellite phones are typically used by pilots, so they need to be installed in the aircraft cockpit. However, the cockpit, as the core area of ​​flight control, has extremely limited internal space and is already densely packed with various flight instruments, control systems, and communication equipment. Under these circumstances, the installation of new phones must not only meet relevant airworthiness regulations, but also be convenient for pilots to access, without affecting the pilot's operating space and line of sight, and without hindering the normal use and maintenance of existing equipment. Therefore, the installation of new phones is quite challenging. Summary of the Invention

[0004] The first objective of this invention is to provide an installation structure for mounting domestically produced satellite phones on aircraft that is simple in structure, robust and reliable, and easy to use and maintain.

[0005] The first objective of this invention is achieved through the following technical measures: an installation structure for mounting a domestically produced satellite phone on an aircraft, characterized in that it includes a storage cabinet located behind the co-pilot's seat in the cockpit, a phone, and a mounting bracket for mounting the phone. The storage cabinet is an existing storage cabinet in the cockpit with the door assembly and fixing straps removed. A mounting base for mounting the door assembly and fixing straps is provided on the right side wall panel of the storage cabinet. A first mounting hole is added to the rear wall panel of the storage cabinet, and the phone socket is installed in the first mounting hole. A second mounting hole is added to the right side wall panel of the storage cabinet, and a support plate nut is installed on the back of the second mounting hole. The mounting bracket is fixed to the right side wall panel by the support plate nut and the mounting base.

[0006] This invention features a simple, robust, and reliable structure, making it convenient for pilots to use and mechanics to maintain. It also meets the requirements for stable and reliable operation of the radio under conditions of vibration, impact, and temperature changes. Furthermore, this invention makes full use of the limited space in the cockpit, utilizing the original mounting base based on the characteristics of its storage cabinet structure, reducing modifications to the original aircraft parts. Moreover, it has undergone rigorous strength verification to ensure that the installation structure meets the strength requirements of relevant regulations.

[0007] The mounting bracket of the present invention is folded plate shaped, consisting of a central groove and folded edges on both sides of the groove. The bottom surface of the groove is provided with reserved holes for the telephone plug and cable to pass through. One side of the folded edge is connected to the right wall panel through a mounting base for mounting the cabinet door assembly, and the other side of the folded edge is connected to the right wall panel through a mounting base for mounting the fixing strap and a support nut. The internal space of the groove serves as the routing space for the telephone cable.

[0008] The second objective of this invention is to provide an installation method for the aforementioned installation structure for mounting domestically produced satellite phones on an aircraft.

[0009] The second objective of this invention is achieved through the following technical measures: an installation method for the aforementioned installation structure for mounting domestically produced satellite phones on an aircraft, characterized by comprising the following steps:

[0010] S1. Remove the cabinet door assembly and fixing straps of the storage compartment behind the co-pilot in the cockpit. A mounting base for installing the cabinet door assembly and fixing straps is left on the right side panel of the storage compartment.

[0011] S2. Drill a first mounting hole on the back panel of the locker and a second mounting hole on the right side panel of the locker.

[0012] S3. Install the telephone socket on the first mounting hole, and install the bracket nut on the back of the second mounting hole;

[0013] S4. Grind the electrical contact surface at the corresponding position on the right side panel of the mounting bracket and the locker;

[0014] S5. Pass the phone plug and cable through the reserved hole of the mounting bracket, then fix the phone on the mounting bracket, and measure the resistance value X between the phone and the mounting bracket.

[0015] S6. Using the mounting base and tray nut, install the mounting bracket with the telephone onto the right side panel, and measure the resistance value Y between the mounting bracket and the right side panel.

[0016] S7. When the sum of resistance values ​​X and Y meets the requirements, store the telephone cable in the storage cabinet and install the telephone plug into the telephone socket to complete the installation of the domestic satellite telephone.

[0017] In step S2 of the present invention, burrs are removed from the first mounting hole and the second mounting hole, and a chemical conversion coating is applied.

[0018] Compared with the prior art, the present invention has the following significant effects:

[0019] (1) This invention utilizes the storage cabinet behind the co-pilot's seat, which was originally used to store the flight logbook. The cabinet door assembly and fixing straps are removed, and a mounting bracket is added to the right side panel of the storage cabinet using the mounting base and fasteners of the cabinet door hinges, thereby providing a mounting position for the telephone. The installation structure of this invention meets the requirements of relevant airworthiness regulations, has sufficient static strength, and also meets the conditions for the telephone to work stably and reliably in environments with vibration, impact, and temperature changes. It makes full use of the very limited physical space in the aircraft cockpit, making it convenient for the pilot to access the telephone without affecting the pilot's operating space and line of sight. Therefore, this invention is a simple, stable, reliable, easy-to-use and maintain installation solution.

[0020] (2) The installation of the back cable of the telephone in this invention is limited by a minimum bending radius, while the installation bracket with an "Ω" shaped cross section in this invention can leave appropriate cable routing space on its back. Attached Figure Description
