Description

Air exhaust type expansion wave artillery

Technical Field

The utility model belongs to weaponry development field, concretely relates to bleeder inflation ripples gun.

Background

When the artillery is launched, the artillery barrel bears the high pressure of gunpowder gas and throws out the shot at a high speed. In recent years, an expansion wave artillery is actively researched at home and abroad. The principle is as follows: the rear end of the gun tail is provided with a spray pipe, when the projectile moves to a certain position in the barrel bore, the breech is opened, so that the propellant gas in the bore is sprayed out from the spray pipe at the rear end of the barrel, and the pressure in the propellant chamber is reduced along with the propellant gas. Because a certain time is required for transmitting the pressure drop to the bottom of the projectile (the transmission speed is the same as the transmission speed of sound waves and is called as an expansion wave), the time for opening the breech bolt is accurately controlled, so that the projectile is not influenced by the pressure drop, and the pressure in the chamber is reduced. The expansion wave artillery can greatly reduce the bore pressure of the artillery, but a flame injection area is formed at the rear part during shooting, so that the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

Furthermore, the number of the exhaust holes is 4-6, and the exhaust holes are uniformly distributed on the same section of the barrel.

Furthermore, the air inlet hole is positioned behind the air outlet hole.

Further, the controller is connected with a gun power supply through a cable.

Further, the controller is a PLC, a singlechip or a PC

The beneficial effects of the utility model reside in that: the utility model provides a new-type gun transmission principle has the advantage of inflation ripples gun-can reduce barrel thorax pressure under the prerequisite that does not influence the pellet initial velocity, has overcome inflation ripples gun flame to rear spun shortcoming, can bleed after the pellet goes out the thorax simultaneously.

Detailed Description

As shown in fig. 1, an air extracting type expanding wave artillery comprises a barrel, a cradle 1 arranged at the rear part of the barrel, a breech 2 at the tail end of the barrel, and a breech bolt 3 arranged in the breech 2; the barrel comprises a guide section 4, an air exhaust section 5 and an emergent section 6; the guide section 4 is connected with the cradle 1 (the cradle is cylindrical), so that the barrel can move back and forth; the inner cavities of the guide section 4, the air exhaust section 5 and the emergent section 6 are all truncated cone-shaped cavities and are in smooth transition (forming a barrel inner cavity). The projectile is guided by the guiding section to enter the air exhaust section and is ejected out of the barrel through the exit section.

An air storage cylinder 15 is sleeved outside the air extraction section 5, an air inlet 7 and an air outlet 8 which are communicated with the air storage cylinder 15 and the air extraction section 5 are arranged at the tail part of the air extraction section 5, the air inlet 7 is arranged along the radial direction of the barrel, and the air outlet 8 is obliquely arranged towards the front end of the barrel; an air inlet valve 9 is arranged on the air inlet hole 7, and an exhaust valve 10 is arranged on the exhaust hole 8; the intake valve 9 and the exhaust valve 10 are connected to a controller 12 via a cable 11.

The number of the air inlet holes 7 is 4-6, and the air inlet holes are evenly distributed on the same cross section of the barrel. The exhaust holes 8 are 4-6 and are uniformly distributed on the same section of the barrel. The air inlet 7 is positioned behind the air outlet 8.

The controller 12 is connected to a gun power supply 13 through a cable 11. The controller 12 is a PLC, a single chip microcomputer or a PC.

The working principle is as follows: after the shell is fired, gunpowder is burnt, the gunpowder gas pushes the shot to move forwards, at a certain moment when the shot moves in the bore, the controller closes the exhaust valve, opens the air inlet valve, gunpowder gas in the barrel bore enters the gas storage cylinder, and the pressure in the bore is reduced. The controller controls the opening time of the inlet valve so that the decrease in the pressure in the chamber does not affect the movement of the projectile. After the projectile 14 flies out of the muzzle, the controller closes the air inlet valve and opens the exhaust valve, because the pressure in the air storage cylinder is higher than the pressure in the bore, the gas in the air storage cylinder flows out at high speed along the exhaust hole, and because the direction of the airflow inclines towards the muzzle, the gunpowder gas at the part of the powder chamber is taken out of the barrel, so that the purpose of air exhaust is achieved.

This bleeder inflation wave gun combines inflation wave gun and air exhaust device's principle together, can effectively reduce the thorax and press, avoids gunpowder gas to spout from barrel rear, reaches the purpose of bleeding simultaneously, provides a new thinking for the gun transmission.
