Abstract
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
The invention belongs to aeronautic structure protection field, relate to a kind of vibration absorber weakening gun gun muzzle energy impact.
Background technology
Gun has positive effect in support ground attack, and object of attack to aerial target, on a surface target, can can be used for attack, and can be used for defence, is the indispensable important weapon of modern operation aircraft.But the big gun problem of shaking that produces after firing shells of part fighter plane Study on Airborne Gun causes damage to a certain degree can to aircraft portions structure, sometimes even can cause structural deterioration or equipment fault.The mechanical oscillation problem that the recoil produced after vibration damping mode is in the past conceived to fire shells more causes, and to gun muzzle high velocity air to the shock problem of surrounding structure seldom solution.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and leave high-speed gas impact energy after bore for weakening gun shell, reduce the damage that it causes gun muzzle surrounding structure.
Technical scheme of the present invention is: a kind of vibration absorber for weakening gun gun muzzle energy impact, is characterized by: described device comprises agent structure 1, syndeton 2, bascule 3, Flexible Reset structure 4;
Described agent structure 1 is an overall structure, comprises three sections: first paragraph is a cylinder, its internal diameter attack with syndeton with the use of screw thread 23, be enclosed within outside gun muzzle gun tube 21; Second segment is the cylinder of truncated cone, and its large end is connected with the 3rd section, and its small end is connected with first paragraph; The barrel of described second segment has the hole 25 of inclination, for release portion high-speed gas; 3rd section is a cylinder, and its inwall is connected with Flexible Reset structure 4 one end;
Two beckets that described syndeton 2 is made for memorial alloy, be enclosed within gun tube 21 respectively, becket is fixed on gun muzzle by self-deformation, becket is attacked with agent structure with the use of screw thread;
Described bascule 3 is a cylinder being enclosed within agent structure 1 the 3rd section, and its internal diameter is greater than gun muzzle external diameter, and inside it, barrel is provided with some depressions 28, for when air-flow passes through, plays inhibition, absorbs the energy of air-flow; Flexible Reset structure 4 one end is connected with bascule, and the other end is connected with the inwall of agent structure, for bascule is retracted origin-location.
Further, described Flexible Reset structure 4 can be spring.
The invention has the beneficial effects as follows: damping device of the present invention can weaken gun shell and leave high-speed gas impact energy after bore, reduces the damage that it causes gun muzzle surrounding structure.
