Problems solved by technology
However, the gun vibration problem caused by the airborne guns of some fighter jets after firing shells will cause a certain degree of damage to some parts of the aircraft structure, and sometimes even lead to structural damage or equipment failure.
In the past, the vibration reduction methods mostly focused on the mechanical vibration caused by the recoil after firing the shell, but there were few solutions to the impact of the high-speed airflow on the muzzle on the surrounding structure.

The invention belongs to the field of aviation structure protection and relates to a vibration damping device capable of weakening the aircraft gun muzzle energy impact. The vibration damping device comprises a main body structure (1), a connecting structure (2), a movable structure (3) and a reset elastic structure (4). The main body structure (1) is of an integral structure and comprises three sections. The connecting structure (2) is two metal rings made from memory alloy, and the two metal rings are arranged on a gun barrel (21) in a sleeving mode. The movable structure (3) is a cylinder arranged in the third section of the main body structure (1) in a sleeved mode. One end of the reset elastic structure (4) is connected with the movable structure, and the other end of the reset elastic structure is connected with the inner wall of the main body structure (1). The reset elastic structure is used for pulling the movable structure back to the original position. The vibration damping device is capable of weakening the high-speed gas impact energy after an aircraft gun shell is separated from a bore and reducing the damage of the impact energy to the gun muzzle surrounding structure.
Description
technical field [0001] The invention belongs to the field of aviation structure protection, and relates to a damping device for weakening the energy impact of the muzzle of an aircraft gun. Background technique [0002] Aircraft guns are of positive significance in supporting ground operations. They can be used for attacking or defending targets in the air or on the ground. They are an indispensable and important weapon for modern combat aircraft. However, the gun vibration problem caused by the airborne guns of some fighter jets after firing shells will cause a certain degree of damage to some structures of the aircraft, and sometimes even lead to structural damage or equipment failure. In the past, the vibration reduction methods mostly focused on the mechanical vibration problem caused by the recoil force generated after firing the shell, but there were few solutions to the impact problem of the high-speed muzzle airflow on the surrounding structure.
