Problems solved by technology

Although there are a variety of recoil reduction devices for conventional artillery, none of them can meet the requirements of consistent initial velocity of internal ballistics when multiple bombs are launched in series with ultra-high radio frequency. Therefore, a new recoil reduction method is needed to meet the above requirements

Embodiment Construction

[0012] The structure of the present invention is to install a front nozzle on the barrel of the multi-bomb serial launch artillery, the opening and closing time and opening degree of the nozzle are controlled by the opening and closing structure, and the opening and closing structure is controlled by the electronic control platform according to computer parameters . Before the projectile is launched, the opening and closing structure is in a closed state to ensure the airtightness in the chamber; when the projectile runs to the preset time, the opening and closing mechanism is opened under the control of the electronic control platform, and the air guide hole connects the front nozzle to the gun body. The tube is connected, and the high-pressure gas in the cavity is ejected through the air guide hole; when the projectile leaves the muzzle, the opening and closing mechanism is closed under the control of the electronic control platform, the air guide hole is closed, and the proj...

Abstract

The invention discloses a front-nozzle type magneto-rheological recoil reduction device for a multi-bomb serial launching artillery, which consists of a gun barrel, a front-end nozzle, a magneto-rheological opening and closing device, an electric stepping mechanism, an electronic Controller composition. There is an air guide hole between the front nozzle and the barrel, so that the high-pressure gunpowder gas at the rear of the moving projectile is discharged from the nozzle in advance; at the same time, the opening time and opening time of the air guide hole when different projectiles are continuously fired are controlled by the magnetorheological opening and closing device. Spend. The invention effectively reduces the recoil when multi-projectiles are launched in series with ultra-high radio frequency, reduces the resistance of the warheads before launching the rear projectiles, improves the firing frequency, and ensures the consistency of the internal ballistic initial velocity of multiple projectiles launched by ultra-high radio frequency. The present invention can also be used for conventional artillery to reduce recoil.

Description

technical field [0001] The invention relates to the technical field of multi-bomb tandem artillery launch, in particular to a front nozzle type magneto-rheological recoil reduction device for multi-bomb tandem artillery. Background technique [0002] Ultra-high radio frequency weapons (also known as metal storm weapons) are a new concept weapon. Although conventional propellant is used, its structural design and launch principle are fundamentally different from conventional artillery. It has no bomb feeding mechanism, recoil device and A series of moving parts such as the shell ejection mechanism, leaving the launch barrel, conventional ammunition and electronic circuits, use the multi-bomb series stacking technology and electronic ignition technology to continuously launch the projectiles from the barrel through electronic pulse ignition to achieve The effective control of the firing sequence of each ammunition and the firing time interval has the characteristics of high ra...
