Front-mounted spray pipe type magneto-rheological recoil reducing device used for multi-bullet series fire cannon

Abstract

The invention discloses a front-mounted spray pipe type magneto-rheological recoil reducing device used for a multi-bullet series fire cannon. The device is composed of a cannon body pipe, a front-mounted spray pipe, a magneto-rheological opening and closing device, an electric stepping mechanism and an electronic controller. A gas guide hole is formed between the front-mounted spray pipe and thebody pipe, and therefore high-pressure gunpowder gas on the rear portions of moving bullets is discharged from the spray pipe in advance. Meanwhile, through the magneto-rheological opening and closingdevice, the opening time and the opening degree of the gas guide hole during continuous launching of different bullets are controlled. By means of the device, the recoil during multi-bullet series ultrahigh radio-frequency launching is effectively reduced, warhead resistance before later-launched bullet launching is reduced, the launching efficiency is improved, and consistency of internal trajectory initial speeds of ultrahigh radio-frequency launching of the multiple bullets is guaranteed. The device can be used for recoil reducing of conventional cannons.

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...

AI Technical Summary

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
