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 aircraft structure protection field and relates to a vibration reduction device for weakening the energy impact of an aerial gun muzzle. The vibration reduction device comprises a main body structure (1), a connection structure (2), a flexible structure (3) and a reset elastic structure (4); the main body structure (1) is an integral structure and comprises three sections; the connection structure (2) comprises two metal rings which are formed by memory alloy and sleeve a gun barrel (21); the flexible structure (3) is a cylinder, wherein the third section of the main body structure (1) sleeves the cylinder; one end of the reset elastic structure (4) is connected with the flexible structure and the other end of the reset elastic structure (4) is connected with the inner wall of the main body structure so as to pull the flexible structure back to the original position. According to the vibration reduction device for weakening the energy impact of the aerial gun muzzle, the impact energy of the high speed gas after an aerial gun shell leaves a gun bore can be weaken and the damage of the impact energy to the structure around the gun muzzle can be reduced.
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.
