Description

Technical Field

[0001] The utility model belongs to the field of aircraft lubricating oil systems and relates to a lubricating oil radiator installation structure used for aircraft lubricating oil systems. Background Art

[0002] Aircraft oil radiator is an important part of the oil cooling system in aircraft engines. Its main function is to absorb and dissipate the heat in the oil, ensuring that the oil runs within the appropriate temperature range to ensure the normal operation and performance of the engine. It plays an important role in ensuring the normal operation and performance of the engine.

[0003] The working principle of the lubricating oil radiator is mainly to use ram air or external cooling medium (such as fuel) to cool the lubricating oil. In turbojet engines, a fuel-lubricating oil heat exchanger is generally used to transfer the heat of the lubricating oil to the fuel, prevent the water in the fuel from freezing, and control the temperature of the lubricating oil. In turboshaft or turboprop engines, an air-lubricating oil radiator is used to cool the lubricating oil through ram air or external air.

[0004] During the operation of the aircraft, the oil radiator needs to be cleaned and maintained regularly to ensure its heat dissipation performance is good. If the radiator is blocked or the heat dissipation performance is reduced, the oil temperature will be too high, which will affect the performance and life of the engine.

[0005] In the past, when operating and maintaining the oil radiator of the aircraft oil system, it was necessary to first dismantle / install the lower hull of the nacelle when dismantling / installing the oil radiator, which was time-consuming and economically expensive, and its maintainability could not meet user requirements. Utility Model Content

[0006] The purpose of the utility model is to overcome the disadvantage of the above-mentioned prior art that when disassembling / installing the lubricating oil radiator, it is necessary to disassemble / install the hull under the nacelle first, and to provide a lubricating oil radiator installation structure for an aircraft lubricating oil system, thereby saving the maintenance time and maintenance cost of the lubricating oil radiator and improving the maintainability of the aircraft.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A lubricating oil radiator mounting structure for an aircraft lubricating oil system comprises two parallel mounting rails;

[0009] Two mounting rails are fixed on the nacelle, and mounting supports are respectively arranged at the bottom of both sides of the lubricating oil radiator. The distance between the two mounting supports is equal to the distance between the two mounting rails. The two mounting supports are respectively slidably connected to the two mounting rails, and the mounting supports and the mounting rails are connected by fasteners.

[0010] Preferably, an oil inlet and an oil outlet are provided on the side of the oil radiator, and the oil inlet and the oil outlet are connected to the inside of the oil radiator and the oil system of the aircraft.

[0011] Furthermore, the lubricating oil inlet and the lubricating oil outlet are located on the same side of the lubricating oil radiator.

[0012] Preferably, the two mounting rails are respectively arranged on both sides of the rear part of the lower hull of the nacelle.

[0013] Preferably, the mounting support and the mounting rail are connected using three fasteners.

[0014] Furthermore, the fasteners are screws and nuts.

[0015] Furthermore, the mounting support and the mounting rail are both provided with through holes corresponding to three positions.

[0016] Preferably, a mounting handle is provided on the lubricating oil radiator.

[0017] Furthermore, a mounting handle is respectively provided on both sides of the lubricating oil radiator.

[0018] Preferably, the lubricating oil radiator is a rectangular parallelepiped structure.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model can save the maintenance time and maintenance cost of the oil radiator and improve the maintainability of the aircraft by providing a set of mounting rails. When the oil radiator is disassembled for maintenance, after providing the disassembly space of the oil radiator, an operator can quickly withdraw the oil radiator from the front to the back, thereby completing the disassembly of the oil radiator. Similarly, when the oil radiator is installed, an operator can push the oil radiator from the back to the front; the oil radiator is fixed on the mounting rails to avoid displacement, and the force received is transmitted to the nacelle through the mounting rails.

[0021] Furthermore, the lubricating oil inlet and the lubricating oil outlet are located on the same side of the lubricating oil radiator, which facilitates the connection of pipelines and avoids the problem of pipelines being intertwined and easily entangled.

[0022] Furthermore, three fasteners are used to connect the mounting support and the mounting rail, thereby improving the mounting strength and preventing the mounting support and the mounting rail from being separated due to vibration during flight of the aircraft.

[0023] Furthermore, an installation handle is provided on the lubricating oil radiator to facilitate workers to install and disassemble the lubricating oil radiator.

[0024] Furthermore, a mounting handle is provided on each side of the lubricating oil radiator, so that the forces on both sides are balanced when the lubricating oil radiator is disassembled and installed, thereby preventing the lubricating oil radiator from tilting to one side and getting stuck on the mounting guide rail.

[0033] like Figure 1 As shown, the lubricating oil radiator installation structure for an aircraft lubricating oil system described in the utility model includes a mounting guide rail 3.

[0034] The oil radiator 1 is a rectangular parallelepiped structure, with an oil inlet 7 and an oil outlet 8 provided on the side. The oil inlet 7 and the oil outlet 8 are used to connect the inside of the oil radiator 1 and the oil system of the aircraft. The oil inlet 7 and the oil outlet 8 are located on the same side of the oil radiator 1 to facilitate the connection of the oil pipeline and avoid the problem of the oil pipeline being intertwined and easily entangled.

[0035] The mounting rail 3 is fixed at the rear of the nacelle 2, specifically, one mounting rail 3 is fixedly arranged on each side of the rear of the lower hull of the nacelle 2, and the two mounting rails 3 are arranged in parallel, with a spacing equal to the width of both sides of the lubricating oil radiator 1. By sliding the lubricating oil radiator 1 on the mounting rail 3 for installation or removal, the removal / installation of the lower hull of the nacelle is avoided, thereby saving time and economic costs.

[0036] Mounting supports 6 are respectively provided at the bottom of both sides of the lubricating oil radiator 1. The distance between the two mounting supports 6 is equal to the distance between the two mounting rails 3. The two mounting supports 6 are respectively slidably connected to the two mounting rails 3, so as to be used for sliding installation or removal of the lubricating oil radiator 1 on the mounting rails 3.

[0037] After the two mounting brackets 6 are connected to the two mounting rails 3, three fasteners 4 are used for fixed connection, and the lubricating oil radiator 1 is fixed on the mounting rails 3 to avoid displacement, and the received force is transmitted to the nacelle 2 through the mounting rails 3. The three fasteners 4 are used to connect the mounting bracket 6 and the mounting rail 3, which improves the installation strength relative to one fastener 4, and prevents the single fastener 4 from loosening due to vibration during flight of the aircraft, thereby causing the mounting bracket 6 and the mounting rail 3 to separate.

[0038] In another embodiment of the present application, the fastener 4 is a screw and a nut, and three through holes corresponding to the positions are provided on the mounting bracket 6 and the mounting rail 3. After the lubricating oil radiator 1 is inserted into the mounting rail 3, when it needs to be fixed, the mounting bracket 6 and the mounting rail 3 are connected by screws and nuts. When the lubricating oil radiator 1 needs to be removed, the screws and nuts can be removed to pull the lubricating oil radiator 1 out of the mounting rail 3.

[0039] The lubricating oil radiator 1 is provided with an installation handle 5, which makes it convenient for workers to install and disassemble the lubricating oil radiator 1; however, since the lubricating oil radiator 1 is heavy and inconvenient to move, when installing and disassembling, if force is applied from only one side to slide on the installation guide rail 3, the lubricating oil radiator 1 is easy to tilt, thereby getting stuck on the installation guide rail 3, affecting the operation. Therefore, in this embodiment, an installation handle 5 is respectively provided on both sides of the lubricating oil radiator 1, the purpose of which is to balance the forces on both sides when the lubricating oil radiator 1 is disassembled and installed, so as to avoid the lubricating oil radiator 1 tilting to one side and getting stuck on the installation guide rail 3.

[0040] In another embodiment of the present application, when installing the oil radiator 1, the oil radiator 1 can be pushed into the mounting rail 3 through the mounting bracket 6 along the installation direction, and the oil radiator 1 can be fixed on the mounting rail 3 through the fastener 4. When disassembling the oil radiator 1, the fastener 4 is removed, and the oil radiator 1 can be pushed out of the mounting rail 3 along the disassembly direction to remove the oil radiator 1.

[0041] At the same time, two installation handles 5 are provided on the lubricating oil radiator 1 to facilitate workers to install and disassemble the lubricating oil radiator 1.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] It should be understood that the above description is for illustration and not for limitation.
