1 Method and apparatus for reducing erosion of inner wall of cylinder JP7815499 1999-03-23 JP2000274997A 2000-10-06 TANAKA TOKUJI; OKUNAGA ICHIRO
PROBLEM TO BE SOLVED: To reduce particularly a burning erosion of an erosion of an inner wall of a cylinder and to prolong a lifetime of the cylinder by injecting a fluid from a rapid missile into the cylinder and cooling the wall of the cylinder. SOLUTION: When a gun propellant M is burned, a large combustion gas pressure is generated. In a dynamic environment during burning of the propellant M, a pressure P1 of a point a is higher than a pressure P2 of a point b. Thus, a cover 13 is slid leftward, and a grease is injected from a nozzle port 14 toward an inner wall 1a. The grease is vaporized by receiving a high heat of the combustion gas. The gas is cooled particularly near the wall by its latent heat. Even if the grease is burned by an influence of the gas of the propellant, a temperature of the generated gas is lower than the temperature of the gas of the propellant. A burning erosion caused particularly by the high temperature of the erosion is remarkably reduced by these effects. Accordingly, a lifetime of the cylinder is prolonged, and a hitting accuracy of a high speed missile is improved. COPYRIGHT: (C)2000,JPO
2 WEAPON SYSTEM EP06795016.2 2006-10-27 EP1941227A1 2008-07-09 WEBB, Michael, John
A weapon system (10) comprises: a barrel (12) for accommodating a projectile (14) in a breech end portion (16); a muzzle end portion (18) and a breech (20). The weapon system further comprises means for purging the barrel comprising a coanda slot (22); a σoanda profile (24) provided downstream of the coanda slot; a source of pressurised gas (26); a duct (28) which connects the source of pressurised gas to the coanda slot (22) so that pressurised gas can be selectively supplied to the coanda slot (22) and along the coanda profile (24) thereby entraining air in the barrel (12) and exhausting debris and/or fumes through the muzzle end portion (18) after firing of a projectile (14); and a valve (30) for controlling flow of gas through the duct (28).

4 Method and apparatus for removing residue in chamber of gun JP17214495 1995-07-07 JPH0926294A 1997-01-28 YOSHIOKA TAKESHI
PROBLEM TO BE SOLVED: To improve the working environment for removing residues in a gun by supplying gas from the breech of the gun. SOLUTION: Gas supply means 10 is disposed at the breech 1a of a gun 1 such that it is inserted removably into a powder chamber 1c. The gas supply means 10 includes an injection part 12 having an injection hole 11, a valve 15, a heat storage unit 13 for storing gas, and a compressor 14. When a residue 3 is left behind in the chamber 1c after a bullet 2 is shot, the injection part 12 of the gas supply means 10 is inserted into the chamber 1c to open the valve 15. Thereupon, gas in the pressure storage unit 13 is injected from the injection hole 11 so that the residue 3 is blown off to a gun outlet 1d side and is removed, and hence the next shooting bullet 2 and gun powder are loaded. Since the residue is removed by the gas, there is no humidity in the chamber when the next gun powder is loaded. Thus, the gun powder is completely prevented from becoming wet so that the shooting interval is reduced and the number of shootings per unit time is more increased than the prior art.

PURPOSE: A method for reducing the sagging of a gun barrel and device for putting into practice such a method is provided to reduce the droop in a gun barrel , caused by a temperature difference between the under side and upper side after firing a number of rounds. CONSTITUTION: To reduce the droop in a gun barrel(1), caused by a temperature difference between the under side(9) and upper side(10) after firing a number of rounds, a gas at a given temperature is fed into the barrel after each round. The gas flow through the bore(7') prevents convection gas flows and temperature differences within the barrel. The gas, of compressed air or nitrogen, can be fed into the barrel from the breech or through a gas extraction unit at the barrel.

Mit der erfindungsgemässen Kühlvorrichtung kann die Lebensdauer von Waffenrohren hochkadenter Rohrwaffen erhöht werden. Zu diesem Zweck wird durch Aufziehen eines Hydraulikkolbens (13) Kühlmittel (7) aus einem Reservoir (6) in einen Druckzylinder (10) gefördert, wobei die Zuleitung (14) zum Waffenrohr (1) geschlossen ist. Danach wird durch Druckumkehr der Hydraulikkolben (13) in die entgegengesetzte Richtung bewegt und das Kühlmittel (7) im Druckzylinder (10) unter einen bestimmten Betriebsdruck gesetzt. Vor dem Auslösen eines Feuerstosses wird die Zuleitung (14) geöffnet, so dass das Kühlmittel über die Zuleitung (14) und die Düse (16) zum Waffenrohr (1) strömen kann. Das Kühlmittel (7) wird jeweils durch den bei der Schussabgabe entstehenden Gasdruck zurückgedrückt und nach dem Absinken des Gasdruckes auf den Betriebsdruck wieder in das Waffenrohr (1) eingespritzt.

17 GUN BARREL COOLER US15236391 2016-08-12 US20170045322A1 2017-02-16 Walter J. Fiedorowicz
A gun barrel cooler for cooling a firearm, such as an automatic, semi-automatic, bolt action or lever action rifle that includes a centrifugal fan blower with an intake to which ambient barrel coolant air is discharged from the blower where the air flows through a conduit that preferably is a flexible hose, through a coupling used to couple the hose to a barrel coolant discharge nozzle, and out the nozzle into the barrel of the gun desired to be cooled. The nozzle is three dimensionally shaped to substantially conform to the firing chamber of the gun to provide better sealing during cooling. A preferred nozzle is an empty cartridge case of substantially the same caliber as the gun to be cooled that is removably attached to the coupler thereby enabling cartridge cases of different calibers to be used to cool guns of different calibers.
18 COOLING DEVICE FOR COOLING COMBUSTION GASES FROM RECOILLESS ANTI-TANK WEAPONS US13811036 2010-07-22 US20130160427A1 2013-06-27 Lars Nilsson
The present invention relates to a cooling device (2) for cooling combustion gases from a rocket motor (1) in an antitank weapon. The cooling device (2) comprises a coolant reservoir (3, 21) containing a coolant (4). The coolant reservoir (3, 21) is arranged such that the coolant (4) is transferred from the coolant reservoir (3, 21) to the combustion gases in the gas outlets (6) of the rocket motor (1) in response to a pressure increase in the rocket motor (1). The coolant reservoir (3, 21) constitutes an integral part of the rocket motor (1) and is connected to the combustion chamber (7) by at least two gas inlets (8) for pressurization of the coolant (4). The coolant reservoir is furthermore connected to the rocket motor nozzle (9) by at least two coolant outlets (10) for transfer of coolant (4) from the coolant reservoir (3, 21) to the rocket motor nozzle (9).

20 Lubricating apparatus for a threaded rifle breech US11505212 2006-08-15 US07793455B1 2010-09-14 Mark C. Laney
A nozzle for lubricating an internally threaded rifle breech. The nozzle has a body containing a bore, with an inlet end adapted to receive a supply of lubricant. The body has an opposed end portion having a cylindrical wall and an enclosed free end. The cylindrical wall has a number of lubricant exit apertures. The body may be L-shaped, and the inlet may be threaded for connection to a lubricant container. The cylindrical wall of the end portion may have an external diameter less than an adjacent portion diameter, so that a shoulder is formed to limit insertion depth. A cap may be provided to cover the exit apertures so that the body may remain attached to the lubricant container.
