    years MILITARY GUNS CATALOGUE Zastava arms Serbia www.zastava-arms.rs Long tradition Zastava arms is the cradle of Serbian industry. In 1851 a decision was made to move the Gun Foundry from Belgrade to Kragujevac and in 1853 first cannon barrels were cast. This ended the efforts of the Principality of Serbia to have its own production of arms and equipment. Gun Foundry in Kragujevac, the center of the Principality of Serbia, quickly developed in material and spiritual way. The Gun Foundry had first steam engines, first electric light, first technical school, first quality system and at the World Fair in Paris, in 1889, the Gun Foundry won several medals. Before the Second World War, the factory was a real industrial giant, with almost twelve thousand employees and ten thousand machines. After the war, the factory started the production of rifle M48, and today Zastava arms produces modern arms and military equipment. Years of experience in the field of development of products, technology and capacities created conditions for the transfer of technology to other countries. As we use CATIA software to design our products, we can quickly respond to the demands of the market. Strategic decision of Zastava arms is a good position of our product in global world market and cooperation with arms manufacturers in the world. By applying Quality Management System (QMS) Zastava arms constantly endeavors to improve the quality of products and all processes. QMS (SRPS ISO 9001:2008 and SORS 9000/05) was re-certified in 2010. Permanent investment in education of staff and purchase of state-of-the-art computer equipment and technology results in placement of new products that follow trends in the world market.

The following component part numbers comprise the compilation report: ADP012452 thru ADP012488 UNCLASSIFIED A FIRE OUT OF BATTERY TANK GUN: THEORY AND SIMULATION E. Kathe and R. Gast' U.S. Army Benit Labs TACOM-ARDEC, Watervliet Arsenal, NY 12189 As part of the Army's Army After Next effort, a radical departure for tank gun recoil was undertaken at TACOM-ARDEC's Benet Laboratories to engineer a soft recoil tank gun. Such a leap in technology may be required to enable a lightweight future combat system to withstand the recoil imparted by a large caliber gun; especially during fire on the move. Although soft recoil is not new to smaller caliber guns and howitzers, implementation for a large caliber tank gun is unprecedented. The theoretical foundations of this recoil management technology will be presented in this paper. Experimental test results of 105mm fire out of battery tank gun demonstrator will be presented in a seperate paper within these proceedings. INTRODUCTION The extreme lethality goals of the future combat system (FCS) program require innovative armament solutions to circumvent traditional engineering barriers.

  • Detail Study of Bullet Being Fired from Gun
    Detail study of bullet being fired from gun DETAIL STUDY OF BULLET BEING FIRED FROM GUN Recoil of a Gun When a bullet is fired from a gun, the gases produced in the barrel exert a tremendous force on the bullet (action force). As a result, the bullet moves forward with a great velocity called the muzzle velocity. The bullet at the same time exerts an equal force on the gun in the opposite direction (reaction force). Due to this the gun moves backwards. This backward motion of the gun is called the recoil of the gun. The velocity with which the gun moves backwards is called the recoil velocity. Recoil of Gun Let 'M' be the mass of the gun and m that of the bullet. Before firing both are at rest. After firing let 'V' be the velocity of the gun and 'v' that of the bullet. By law of conservation of linear momentum, Initial momentum of gun and bullet = final momentum of gun and bullet. The initial momentum of the gun and the bullet is equal to zero since they are initially at rest. Final momentum after firing = M*V + m*v = 0 [The negative sign indicates that the gun is recoiling] Long recoil operation Key for recoil operation diagrams. Block diagram of long recoil operation cycle. Long recoil operation is found primarily in shotguns, particularly ones based on John Browning Auto-5 action. In a long recoil action, the barrel and bolt remain locked together during recoil, compressing the recoil spring or springs. Following this rearward movement, the bolt locks to the rear and the barrel is forced forward by the spring.

The article follows the historical genesis of the development of the use of submachine guns as specific types of small arms. Access to , N. et al, Submachine guns in the arm recent literature represented a major problem; consequently, data from ć the Internet was largely used. Submachine guns are one of the most evi effective and efficient types of infantry weapons of foreign armed forces so č a more versatile look at the effects of their use is purposeful as well as the Kova need for innovation and investing in our own resources.
