Abstract
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
The invention belongs to aeronautic structure protection field, is related to a kind of vibration absorber of decrease gun gun muzzle energy impact.
Background technology
Gun has positive effect in ground attack is supported, and object of attack can be to aerial target, can appearance over the ground
Mark, can be used for attack, can be used to defend, and be the indispensable important weapon of modern operation aircraft.But part fighter plane is airborne
The big gun problem of shaking that gun is produced after firing shells can cause a certain degree of damage to aircraft portions structure, even can lead sometimes
Cause structural deterioration or equipment fault.Being conceived to machinery caused by the recoil institute produced after firing shells conventional vibration damping mode more
Vibration problem, and the little solution of shock problem to gun muzzle high velocity air to surrounding structure.
The content of the invention
The technical problem to be solved is：One kind is provided and leaves high-speed gas after bore for weakening gun shell
Impact energy, reduces its damage caused to gun muzzle surrounding structure.
The technical scheme is that：A kind of vibration absorber for weakening gun gun muzzle energy impact, it is characterized by：Institute
The vibration absorber stated includes agent structure 1, attachment structure 2, bascule 3, Flexible Reset structure 4；
The agent structure 1 is an overall structure, including three sections：First paragraph is a cylinder, and its internal diameter is tapped with and is connected knot
The screw thread 23 that structure is used cooperatively, is enclosed within the gun muzzle outside gun tube 21；Second segment is the cylinder of truncated cone, its big end and the 3rd section of phase
Even, its small end is connected with first paragraph；Inclined hole 25 is provided with the barrel of the second segment, for discharging part high-speed gas；
3rd section is a cylinder, and its inwall is connected with the one end of Flexible Reset structure 4；
The attachment structure 2 is two beckets made by memorial alloy, is respectively fitted on gun tube 21, and becket is by certainly
Body deformation is in itself fixed on becket on the gun tube at gun muzzle, and the screw thread used cooperatively with agent structure is tapped with becket；
The bascule 3 is a cylinder being enclosed within the 3rd section of agent structure 1, and its internal diameter is more than gun muzzle external diameter, in it
Side tube-wall is provided with some depressions 28, for when air-flow passes through, playing inhibition, absorbs the energy of air-flow；Flexible Reset is tied
The one end of structure 4 is connected with bascule, and the other end is connected with the inwall of agent structure, for bascule to be retracted into origin-location.
Further, the 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 punching after bore
Energy is hit, its damage caused to gun muzzle surrounding structure is reduced.
Description of the drawings

Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, a kind of vibration absorber for weakening gun gun muzzle energy impact, described vibration absorber includes
Agent structure 1 shown in Fig. 2, attachment structure 2, bascule 3, Flexible Reset structure 4；
The agent structure 1 is an overall structure, including three sections：First paragraph is a cylinder, and its internal diameter is tapped with and is connected knot
The screw thread 23 that structure is used cooperatively, is enclosed within outside the gun muzzle outside gun tube 21, as shown in Fig. 2 being threaded connection, is anchored on attachment structure
On；Second segment is the cylinder of truncated cone, and its big end is connected with the 3rd section, and its small end is connected with first paragraph；The cylinder of the second segment
Inclined hole 25 is provided with wall, axially bored line is at an acute angle with the big extreme direction of agent structure axis, for discharging part high-speed gas；The
Three sections is a cylinder, and its inwall is connected with the one end of Flexible Reset structure 4；
The attachment structure 2 is two beckets made by memorial alloy, is respectively fitted on gun tube 21, and becket is by certainly
Body deformation is in itself fixed on becket on the gun tube 21 at gun muzzle, and the spiral shell used cooperatively with agent structure is tapped with becket
Stricture of vagina, is threaded connection and vibration-proof structure is fixed on gun muzzle；
The bascule 3 is a cylinder being enclosed within the 3rd section of agent structure 1, and its internal diameter is more than gun muzzle external diameter, in it
Side tube-wall is provided with some depressions 28, for when air-flow passes through, playing inhibition, absorbs the energy of air-flow；Flexible Reset is tied
The one end of structure 4 is connected with bascule, and the other end is connected with the inwall of agent structure, for bascule to be retracted into origin-location.
The Flexible Reset structure 4 is spring.
By said process, this device weakens gun shell and leaves high-speed gas impact energy after bore, reduces it to big gun
The damage that mouth surrounding structure is caused.
