Description

Technical Field

[0001] The invention belongs to the technical field of aircraft external hanging, and relates to a quick-detachable aircraft aircraft gun pod support device. Background Art

[0002] External aircraft cannons are widely used because they are detachable and have little impact on the internal structure and space of the aircraft. However, during flight, the aerodynamic force generated by the external aircraft cannon pod, the gravity of the cannon itself, the recoil generated during shooting, and the vibration load of the cannon put forward higher requirements on the aircraft structure connected to the cannon pod, especially the front joint of the cannon.

[0003] Patent 201710569290.5 relates to an aircraft gun pod support structure, which includes a gun pod body, a threaded bushing, a nut, and a plug. The installation is relatively complicated, the structure does not directly transmit loads, and the connection and fixing form with the gun pod is unclear.

[0004] Patent 201420696604.X relates to a pod lifting lug with a lock, which is connected to the aircraft's lateral main load-bearing frame through a threaded bushing. The directional recoil force generated by the aircraft gun is very limited and is only suitable for the connection interface of external devices that generate a small load. Summary of the invention
