摘要： A muzzleloading firearm has a barrel with a bore on a bore axis, and the barrel has a muzzle end and a breech end. A frame is connected to the barrel, and has a breech face. The frame moves between an open position in which the breech face is away from the breech end of the barrel, and a closed position in which the breech face abuts the breech end of the barrel. A breech plug is removably attached to the barrel. The breech plug including a seal element closely received by the bore. The seal element may be a set of piston rings that are received in a circumferential groove about a forward end of the plug, or may be a cup at the forward end, with a forward rim that flares under pressure to provide a gas seal.

摘要： A long-distance blast banger including a cartridge loaded with a blast banger made up from plastic material. The blast banger encompasses a sound explosives cup and a delay cup. The sound explosives cup is loaded with a sound explosives agent having components including perchloryl potassium, magnesium powder and aluminum powder. A sufficient sound value is acquired through appropriate compacting of the sound explosives cup, and therefrom realizes uniform shattering of the cup into small fragments that are insufficient to cause injury. Furthermore, at least two helical grooves extending from a bottom to a top of the cartridge are defined on an inner wall thereof, and ear attachments are configured on a base of an outer wall of the blast banger so as to correspond with the helical grooves, thereby engendering a spinning stability effect during flight time of the blast banger, reducing wind resistance, and thus increasing flight range.

摘要： Rifling for the barrel of a firearm includes a first gain twist region for increasing the rotational velocity of a bullet as it travels from the breech towards the muzzle end of the barrel, and a second region in which the rifling is of a constant twist so that the bullet exits the muzzle end of the barrel at a constant rotational velocity. The bore defined in the barrel is tapered in a direction from the breech end to the muzzle end so that the diameter of the muzzle opening of the barrel is less than the diameter of the breech opening. The angle of the rifling is variable with the rate of the gain twist of the rifling. The gain twist of the rifling in the barrel is formed by a button, preferably having a sinusoidal shaped periphery, which is pulled through the barrel during the manufacturing process. The smooth periphery of the button prevents shredding of the barrel when the button is twisted at different speeds to provide the variable gain twist of the rifling in different sections of the barrel. In a further aspect of the invention, an apparatus is provided for selectively varying the rotational speed of the button to form the desired gain twist of the rifling during manufacture of the barrel.
摘要翻译： 用于枪械枪的步枪包括第一增益扭转区域，用于当子弹从后枪朝向枪管的枪口端行进时增加子弹的旋转速度，以及第二区域，其中膛线具有恒定的扭转，使得 子弹以恒定的旋转速度离开枪管的枪口端。 在筒体中限定的孔在从后膛端到枪口端的方向上是锥形的，使得枪管的枪口开口的直径小于枪口的直径。 膛线的角度随着膛线的增益扭曲率而变化。 枪管中的膛线的增益扭曲由优选地具有正弦形周边的按钮形成，该按钮在制造过程中被拉过枪管。 当按钮以不同的速度扭转时，按钮的平滑周边防止料筒的破碎，从而在筒的不同部分提供膛线的可变增益扭曲。 在本发明的另一方面，提供了一种装置，用于选择性地改变按钮的旋转速度，以在筒的制造过程中形成期望的膛线增益扭矩。

摘要： The present invention relates to a gun tube having a spin curve with a variable spin angle as well as a rifling force R(x) over the path of the projectile (x) through the gun tube when a projectile is fired, as well as a predetermined caliber d, projectile mass m.sub.G, mass moment of inertia J about the longitudinal axis of the projectile, gas pressure force P(x) on the projectile bottom and projectile velocity v(x). In order to realize, within the framework of manufacturing tolerances, an accurate spin curve corresponding to diverse desired characteristics of the rifling force, it is provided that the rifling force R(x) is determined according toR(x)=R.sub.max R.sub.n (x)where R.sub.max is the maximum rifling force value which is a function of a predetermined final spin angle .beta..sub.E and R.sub.n (x) is a predetermined, standardized rifling force curve with a defined onset of spinning, a defined initial spin angle and a defined spin profile, with the development of the spin on the caliber diameter being determined from the following differential equation: ##EQU1## and from R.sub.max for a given final spin angle .beta..sub.E.

摘要： The disclosure relates to a method of producing rifled, non-metallic barrels of composite material in the form of a fiber-reinforced thermosetting matrix for rocket and grenade launcher ordnance, and barrels produced in accordance therewith. The characterizing feature of the present invention is that this results in barrels with the same fiber content in both the lands of the barrel rifling and in its rifling grooves which has been realized in that a porous fluffy mat with a high capacity to absorb the matrix material is employed in the rifled portion of the barrel.

摘要： The invention discloses a gun barrel with a novel pattern of a rifling curve. The latter proceeds at start of motion from the parabolic curve y=A+Bx+Cx.sup.2 and is supplemented with a constant D, to which is added a freely selectable exponent =d. Due to the freely selected exponent as parameter the ridge force maximum can be displaced at almost equal level between the start of motion and the barrel mouth. At the barrel mouth the ridge force drops to a minimum.

摘要： A rifled gunbarrel has stepped relief narrowing width of lands on the sides which normally transmit torque to projectiles, the narrowing extending about one projectile length to the muzzle for isolating the influence of torsional relaxation of gunbarrel, which is normally a trajectory-perturbing factor on projectile emergence, while continuing radial contact for projectile guidance along the gunbarrel axis as the gunbarrel unwinds.
