Description
Technical Field
The invention belongs to the technical field of artillery design, and particularly relates to a combined balance body structure meeting the requirement of stable internal trajectory and an assembling method thereof.
Background
The balance gun is a product produced by the rapid rise of the national defense industry in recent times, and is mainly characterized by large caliber, high initial speed, large kinetic energy and small recoil. Compared with artillery, the balance artillery has much larger charge, length and quality of a barrel and a fixing and supporting device; therefore, the balance cannon is more heavy than the cannon and is inconvenient to transport; but its power is also greater than that of a gun.
The balance gun offsets the backward impact force generated by the shot launching by adding a balance body into the rear end opening of the gun body, thereby reducing the recoil force of the gun body. The gunpowder in the body tube burns and applies work to the projectile and the balance body at the same time, so that the momentum of the projectile and the momentum of the balance body are equal and opposite; the balance mass also has a high kinetic energy and is vulnerable to damage after ejection. In most guns, the high kinetic energy of the shot when it is fired can improve the power of the shot; the balance body is used as a 'bullet' which can be repeatedly used, and the high kinetic energy can cause the self damage. Rather than being a "consumable" projectile, the reuse of the balance can greatly reduce expenditure and speed up the testing process. The processing difficulty of the object is determined by the size and the shape, although the shape of the balance body is more regular, the weight and the volume are larger (the mass of the balance body can reach 2 tons or more), and the whole block is difficult to process and form. The damage to the whole balancing body is generally serious, and the repair process is complex and difficult; even the whole body can only be replaced when the device is unable to be repaired and recovered. In addition, the test working conditions of the balance guns can be different, corresponding balance bodies have different masses in order to meet the requirement of no recoil, and the type of the integral balance body matched with each balance gun is limited. In summary, other methods are needed to optimize the design of the balance body. Both ends of the barrel of the balance gun are provided with the 'emitters', and the ignition device and the ignition mode of the balance gun also need to be redesigned so as to ensure the convenience and stability of ignition and the air-tightness of an ignition channel.
