This quick-release aircraft gun pod support device is installed in conjunction with the gun base, thereby achieving the connection and fixation of the externally mounted gun to the aircraft body.

Description

Technical Field

[0001] This invention belongs to the field of aircraft external attachment technology and relates to a quick-release aircraft gun pod support device. Background Technology

[0002] Externally mounted cannons are widely used due to their detachability and minimal impact on the internal structure and space of the aircraft. However, during flight, the aerodynamic forces generated by the externally mounted cannon pod, the weight of the cannon itself, the recoil generated during firing, and the vibration load of the cannon place high demands on the airframe structure connected to the cannon pod, especially the cannon's front joint.

[0003] 201710569290.5 relates to an aircraft gun pod support structure, which includes a gun base, a threaded bushing, a nut, and a plug. The installation is relatively complex, the load transfer is not direct, and the connection and fixing method with the gun pod is not clear.

[0004] 201420696604.X relates to a locking pod lug, which is connected to the aircraft's transverse main load-bearing frame via a threaded bushing. It has very limited capacity to withstand the directional recoil force generated by the cannon and is only suitable for connecting interfaces of external load-bearing devices with small loads. Summary of the Invention

[0005] Purpose of the invention

[0006] To address the issues of cumbersome assembly and indirect load transfer in aircraft gun pod supports, a simple, quick-release aircraft gun pod support device was invented that facilitates the installation and disassembly of the gun pod.

[0007] Technical solution

[0008] A quick-release aircraft gun pod support device includes a gun pod support, a chuck, and an end cap. The gun pod support is positioned and fixed to the aircraft structure by a locator. The gun pod support has mounting holes for the gun base, and the mounting holes have inner flanges. The number of inner flanges is the same as the number of outer flanges on the gun base. The chuck body is a circular ring structure. The outer ring has two symmetrically distributed chuck bosses, and the inner ring has symmetrically distributed chuck grooves. The chuck bosses and chuck grooves are located at the same position on the circular ring structure.

[0009] After the gun base passes through the gun pod support, it rotates 90° until the lower surface of the outer flange of the gun base is in contact with the upper surface of the inner flange of the gun pod support hole, ensuring maximum contact surface. The chuck is installed on the gun pod support, ensuring that the two chuck bosses of the chuck are located in the support grooves on the gun pod support, and the two outer lugs of the gun base are located in the chuck grooves of the chuck. The end cap is installed on the chuck, and the internal thread on the end cap is screwed into the external thread on the gun base.

[0010] Furthermore, it also includes a fuse that passes through the end cap and the gun mount to secure the end cap and the gun mount in place.

[0011] Furthermore, the gun pod support is made of aluminum alloy.

[0012] Furthermore, the chuck is made of 30CrMnSiA.

[0013] Furthermore, the end cap is made of 30CrMnSiA.

[0014] Furthermore, the support groove is specifically a blind groove.

[0015] Furthermore, the inner flange of the hole is rounded.

[0016] The beneficial effects of this application are as follows:

[0017] The quick-release aircraft gun pod support device of the present invention comprises three parts: a gun pod support 1, a chuck 2, and an end cap 3, which realizes the installation and fixation of the gun pod. Figure 1 As shown, the aircraft gun pod support 1 is integrated with the aircraft structure, meeting the strength requirements for the gun pod and gun firing.

[0018] This invention discloses a quick-release aircraft gun pod support device. The support and aircraft structure are designed as an integral unit: the front and rear ends of the gun pod support 1 are bolted to the aircraft fuselage frame; longitudinal beams with corner box bottoms on both sides of the support participate in the overall stress distribution of the aircraft; the inner diameter of the hole in the middle of the gun pod support is designed with two built-in slots for Y-axis positioning with the gun pod; the inner diameter of the hole is designed with two rectangular annular grooves; the two lugs of the chuck 2 mate with the grooves of the support; the inner grooves mate with the built-in connector of the gun pod, restricting the rotation between the gun pod and the support; the end cap 3 has internal threads, serving as the threaded connection for the gun pod connector, restricting the Y-axis movement of the chuck; and the end cap 3 has multiple safety holes on its end face.
