| 41 | Gun barrel and method of forming | US11115929 | 2005-04-27 | US07721478B2 | 2010-05-25 | James C. Withers; Lori A. Bracamonte; Roger S. Storm; Sion M. Pickard; Raouf O. Loutfy |
| A fabrication technique is described for producing lighter weight and improved wear and erosion resistant gun barrels. The barrels are produced in an unconventional manner from the inside bore to the outside diameter of the barrel and combine a refractory metal, metal alloy, or ceramic composite inner liner with a metal matrix composite (MMC) or titanium or other suitable high strength, lightweight metal or metal alloy outer shell. A unique aspect of the invention is that there is a compositional gradation from the liner at the inside bore to the overwrap which extends to the outside diameter of the barrel. A process is also described to produce barrels with a refractory metal liner with improved wear and erosion resistance by depositing the refractory metal on the ID of a pre-fabricated barrel. | ||||||

| The invention provides a barrel for a gun having a portion comprising a substantially transparent material. The barrel can be made of any substantially transparent material including a polycarbonate or glass, such as tempered glass. The barrel is coated with a substantially transparent material to add hardness, which provides scratch resistance, and prevent deterioration of the substantially transparent material. A barrel assembly is constructed by attaching the barrel to a gun housing, also called a barrel cage, comprised of a stiff material, for example metal such as aluminum. In another aspect of the invention, an expansion chamber is provided having a housing with a portion comprising a substantially transparent material, such as a polycarbonate or glass, such as, tempered glass. The housing is coated with a substantially transparent material to reduce scratching and absorption of pressurized gas into the transparent material. The housing is partially enclosed within a cage to provide additional protection and stiffness to the expansion chamber. | ||||||

| A gun barrel for a gun has an elongated tube with an axial bore extending completely through the tube from the breech end to the muzzle end. The tube and the contact surface in the axial bore, which contains propellant gasses behind the projectile and engages the projectile while guiding it toward the target, are made of Nitinol having a transition temperature lower than the lowest ambient temperature at which a gun with the barrel is designed to be operated, or of a Nitinol formulation consisting essentially of 60% nickel and 40% titanium. A first sleeve may be mechanically coupled to the barrel tube by shape memory contraction thereon to prestress the barrel tube in compression. The first sleeve may be made of a Nitinol composition having a Martensite state and an Austenite state existing naturally on opposite sides of a transition temperature lower than the designed normal lower ambient temperature in which the gun operates, whereby the sleeve composition remains in the Austenite state during operation of the gun and provides substantial compressive preloading of the tube during operation. A second sleeve of a Nitinol composition having a transition temperature higher than the designed normal operating temperature of the gun is encased within the first sleeve, whereby the second sleeve composition remains in the Martensite state during normal operation of the gun and provides substantial damping of vibrations and whipping of the gun barrel in operation. | ||||||

| The method for producing tubes for heavy guns employs a heat-treatable steel, consisting in wt.-% of 0.20 to 0.50% carbon, max. 1.0% silicon, max. 1.0% manganese, max. 0.03% phosphorus, max. 0.03% sulfur, max. 0.1% aluminum, max. 4% nickel, max. 2% chromium, max. 1% molybdenum, max. 0.5% vanadium, and the remainder of iron and the customary impurities. Forgings of open-smelted cast ingots are pre-worked on a lathe on the outside. The solid blanks obtained in this way are hardened and tempered, only subsequently drilled and then finished. | ||||||

| 46 | Projectile-launcher actuated by induction | US662516 | 1991-02-28 | US5088381A | 1992-02-18 | Etienne Lamarque; Jacques Rabuel, deceased; Jean Sikora |
| In a projectile-launcher actuated by induction, the guidance tubes are made of austenitic, stainless steel with high resistivity, transparent to the induction phenomenon. This makes it possible to obtain optimal mechanical strength while at the same time deriving the benefit of the advantages of actuation by induction between an inducation coil wound on each tube and an armature winding wound on the projectile. The disclosed device can be applied to all types of ground or airborne rocket-launchers. | ||||||

| The invention is directed to the construction of weapon barrels from a steel core and at least one metal-matrix material sleeve, forming a composite metal-metal-matrix barrel which are applicable in rifles, shotguns, cannons, and mortars. Due to the properties of the metal-matrix materials (e.g. higher specific strength, higher specific heat capacity and lower density), the composite barrels can exhibit a higher rate of fire, reduced weight, improved accuracy, or a combination of any of these properties. Disclosed are various exemplary embodiments of such barrels with improved performance, properties of the metal-matrix materials necessary to allow these improvements as well as methods to produce the same. | ||||||
